  • Whey vs. Plant Protein for Muscle Growth: Which Wins?

    Whether you’re new to resistance training or a seasoned lifter, you’ve probably asked yourself this question: Should I go with whey or plant-based protein to build muscle? With so many options lining the shelves, it can be hard to know which one truly delivers when it comes to gains.

    In this post, I’ll break down the differences between whey and plant-based protein using the latest research, and help you decide which one fits your goals best. Plus, I’ll link a few good options you can check out for yourself.

    Whey Protein: Fast, Complete, and Proven

    Whey protein comes from milk and is widely regarded as the “gold standard” for muscle growth. It’s a complete protein, meaning it contains all nine essential amino acids, and it’s particularly rich in leucine one of the most important amino acids for triggering muscle protein synthesis (Tang et al., 2009).

    Because it’s rapidly digested and absorbed, whey is ideal for post-workout recovery. Numerous studies have shown that whey protein is highly effective for increasing muscle mass when combined with resistance training (Phillips et al., 2009).

    Pros:

    • High in leucine

    • Fast digestion

    • Strong evidence base

    • Often more affordable per gram of protein

    Cons:

    • Contains dairy—may cause issues for those with lactose intolerance

    • Not suitable for vegans

    Plant-Based Protein: Cleaner, Greener, and Surprisingly Effective

    Plant proteins are derived from peas, rice, soy, hemp, and other plant sources. On their own, some of these can be lower in certain essential amino acids, but when blended (like pea + rice), they can provide a complete protein profile.

    Recent research (Monteyne et al., 2023) has shown that when plant-based proteins are matched for leucine content, they can stimulate muscle protein synthesis just as effectively as whey.

    A systematic review by Mariotti and Gardner (2024) further supports this, concluding that plant-based proteins, when consumed in sufficient quantities and combinations, can support muscle gains comparable to animal-based proteins.

    Pros:

    • Suitable for vegans and those with dairy intolerance

    • Lower environmental impact

    • Often easier to digest for sensitive stomachs

    Cons:

    • Usually requires slightly more to match leucine levels

    • Some products can be gritty or chalky in texture

    How Do They Compare?

    When it comes to building muscle, both whey and plant-based proteins can do the job but they differ in a few key ways:

    • Amino Acid Profile:

    Whey protein naturally contains all nine essential amino acids, with a high leucine content that makes it especially effective for stimulating muscle growth. Most plant-based proteins, unless blended (like pea and rice), may lack one or more essential amino acids. However, many modern formulas are now fortified or combined to offer a complete profile.

    • Digestion Speed:

    Whey is rapidly digested, making it a great option for post-workout recovery. Plant proteins tend to digest more slowly, which can be beneficial for sustained satiety, though not quite as ideal immediately after training.

    • Muscle-Building Evidence:

    Whey is backed by decades of research supporting its role in increasing lean muscle mass. Plant proteins are catching up, with newer studies showing that, when properly formulated and consumed in adequate amounts, they can support similar gains.

    • Diet Compatibility:

    Whey comes from milk, so it’s not suitable for vegans or those with lactose intolerance. Plant-based proteins, on the other hand, are dairy-free, vegan-friendly, and often easier on the stomach.

    • Sustainability:

    Plant proteins generally have a lower environmental impact, making them a more sustainable choice for those who are eco-conscious.

    In short: Whey is a reliable, fast-acting option with a robust track record. Plant protein is a solid alternative especially when blended and thoughtfully formulated with added benefits for dietary inclusivity and sustainability

    Top Picks

    Whey Protein:

    • Optimum Nutrition Gold Standard Whey

    Plant-Based Protein:

    • Optimum Nutrition Gold Standard 100% Plant

    So… Which One Wins?

    Honestly? It depends on your lifestyle, preferences, and dietary needs.

    • If you’re not vegan and want fast absorption with a strong evidence base, whey is a fantastic option.

    • If you follow a plant-based diet or want a more eco-conscious choice, plant protein especially in blended or fortified forms is a powerful alternative.

    The key to building muscle isn’t just what protein you use, but how consistently you train, recover, and eat to support your goals

  • The Foundations of Performance Nutrition: Why Timing, Type, and Total Matter

    When it comes to enhancing performance whether in sport, exercise, or day-to-day energy demands nutrition is far more than just “eating healthy.” It’s a science-driven approach that focuses on fuelling the body in a strategic way to optimise energy, recovery, strength, and endurance. At the core of performance nutrition lies three crucial pillars: timing, type, and total intake. When these elements are aligned, they create a powerful framework to support physical performance and recovery. Let’s break each of these down.

    1. Timing: When You Eat Matters

    Nutrient timing is all about when you eat in relation to training or activity. Eating the right foods at the right times can enhance energy availability, reduce fatigue, and accelerate recovery.

    Pre-training: Fuel up with a mix of carbohydrates and a small amount of protein 1–3 hours before exercise to ensure glycogen stores are topped up and muscles are primed. During training: For longer sessions (especially over 60–90 minutes), intra-workout nutrition like simple carbs and fluids can help maintain energy and hydration. Post-training: Recovery nutrition is vital. Consuming carbs and protein within 30–60 minutes post-exercise helps replenish glycogen stores and kickstarts muscle repair.

    Ignoring nutrient timing can lead to under-fuelling, sluggish sessions, and prolonged recovery.

    2. Type: What You Eat Matters

    All calories are not created equal especially when it comes to performance. The type of macronutrients (carbohydrates, proteins, and fats) and micronutrients (vitamins and minerals) you consume plays a major role in how your body performs.

    Carbohydrates are the body’s preferred source of energy during high-intensity activity. Think whole grains, fruits, starchy veg, and sports-specific fuel like energy gels when needed. Protein is essential for muscle repair, growth, and overall recovery. Aim for lean protein sources like poultry, eggs, dairy, legumes, and plant-based alternatives. Fats, while often overlooked, are key for long-lasting energy and hormone function especially in endurance athletes. Prioritise healthy fats like avocado, nuts, seeds, and oily fish. Hydration and electrolytes are just as important as food without them, energy and focus can quickly drop.

    Matching the type of food to your activity and goals helps the body perform efficiently and recover faster.

    3. Total: How Much You Eat Matters

    Even with perfect timing and the right types of food, performance can still suffer if you’re under-fuelling or over-fuelling. Your total intake the quantity of calories and nutrients needs to align with your energy output and individual goals.

    Under-eating can lead to low energy availability, poor recovery, fatigue, and increased injury risk. Over-eating may cause sluggishness, weight gain, and reduced performance in sports that require speed or agility. Individual needs vary depending on training intensity, frequency, body composition goals, and metabolic rate there’s no one-size-fits-all.

    Working with a nutritionist or using tracking tools can help athletes find the sweet spot that meets their specific energy demands.

    Final Thoughts: The Big Picture

    Performance nutrition isn’t just about what you eat it’s a strategic combination of when, what, and how much you eat. These three pillars timing, type, and total are the backbone of effective fuelling for performance. Whether you’re training for a marathon, lifting heavy in the gym, or simply looking to feel more energised and focused in your daily life, getting these fundamentals right is essential.

    By fine-tuning these elements, you’re not just eating you’re fuelling with purpose.

  • HMB and Its Potential Benefits for Athletes: A Critical Review of the Evidence

    Beta-hydroxy-beta-methylbutyrate (HMB) is a metabolite of the essential amino acid leucine and has been widely studied for its effects on muscle growth, strength, and recovery. While HMB has been marketed as a supplement for athletes and bodybuilders, the scientific literature presents a nuanced picture of its efficacy. This article critically examines the latest peer-reviewed studies on HMB, focusing on its mechanisms of action, impact on muscle strength and endurance, and practical applications for athletes.

    Mechanisms of Action

    HMB’s purported benefits stem from its ability to:

    1. Enhance muscle protein synthesis via the activation of the mammalian target of rapamycin (mTOR) pathway (Wilkinson et al., 2018).
    2. Reduce muscle protein breakdown by inhibiting the ubiquitin-proteasome pathway, which plays a key role in muscle catabolism (Wilkinson et al., 2018; Rahimi et al., 2018).
    3. Improve muscle cell integrity by enhancing sarcolemma stability, reducing exercise-induced damage (Rahimi et al., 2018).

    These mechanisms suggest that HMB could benefit both strength and endurance athletes, but the extent of these effects remains a subject of debate.

    HMB and Muscle Strength: Trained vs. Untrained Athletes

    Untrained or Beginner Athletes

    Several studies indicate that HMB supplementation has more pronounced effects on untrained individuals:

    • A meta-analysis by Rahimi et al. (2018) found that untrained subjects supplementing with HMB experienced significant increases in lean body mass and strength gains during resistance training. This aligns with earlier studies, such as Nissen et al. (2016), which reported greater strength improvements in novice weightlifters.
    • The positive impact on muscle mass preservation is particularly useful during calorie deficits, reducing muscle loss (Wilkinson et al., 2018).

    Trained Athletes and Strength Gains

    Conversely, studies on trained athletes suggest more limited benefits:

    • Rahimi et al. (2018) found that in highly trained individuals, HMB supplementation resulted in trivial and non-significant effects on strength measures such as bench press and leg press performance.
    • These findings are consistent with Wilson et al. (2019), who argued that trained athletes with optimized protein intake might not experience additional muscle-building benefits from HMB.

    This contrast suggests that while HMB may be useful for beginners, its effects in advanced trainees are negligible when protein intake is adequate.

    HMB and Endurance Performance

    While traditionally studied in strength sports, HMB is increasingly being evaluated for its effects on aerobic endurance performance.

    • Fernández-Landa et al. (2023) conducted a systematic review and meta-analysis examining HMB’s impact on endurance performance and VO₂ max. Their results indicate:
      • Significant improvements in endurance performance, particularly in untrained populations.
      • Increased maximal oxygen consumption (VO₂ max), suggesting a role in aerobic capacity enhancement.
      • Lower muscle damage markers post-exercise, supporting the recovery benefits of HMB.

    These findings align with earlier work by Wilson et al. (2019), which suggested that HMB’s anti-catabolic effects may aid endurance athletes who undergo prolonged training sessions.

    HMB and Recovery: The Anti-Catabolic Effect

    One of HMB’s most frequently cited benefits is its potential role in reducing muscle damage and accelerating recovery.

    • Reduced Muscle Soreness:
      • Wilkinson et al. (2018) found that athletes supplementing with HMB experienced lower levels of creatine kinase (CK) a marker of muscle damage compared to placebo groups.
      • This aligns with Rahimi et al. (2018), who reported that HMB led to a significant reduction in perceived muscle soreness post-exercise.
    • Faster Recovery:
      • Fernández-Landa et al. (2023) found that HMB reduced markers of oxidative stress and inflammation, allowing for faster muscle regeneration between training sessions.
      • This supports findings by Wilson et al. (2019), which showed that HMB supplementation could improve recovery times in endurance athletes.

    Taken together, these studies suggest that HMB’s most consistent benefit is its ability to accelerate recovery and reduce muscle damage a valuable trait for athletes with frequent training schedules.

    HMB and Hormonal Responses

    Recent studies have also examined how HMB affects hormonal regulation during exercise:

    • Cortisol Reduction: Fernández-Landa et al. (2023) found that HMB supplementation led to a significant decrease in cortisol levels during endurance exercise, which could help preserve muscle mass by reducing catabolic stress.
    • Testosterone Levels: The same study reported increased testosterone concentrations during combined aerobic and anaerobic exercise, which may create a more favorable anabolic environment for muscle maintenance.

    These hormonal effects support the findings of Wilson et al. (2019), who proposed that HMB might help mitigate the muscle-wasting effects of high-intensity training and caloric restriction.

    Dosage, Safety, and Practical Considerations

    Recommended Dosage

    • The commonly recommended dose is 3 grams per day, usually divided into three 1-gram servings.
    • HMB is available in calcium salt (HMB-Ca) and free acid (HMB-FA) forms, with some studies suggesting that HMB-FA has faster absorption rates (Wilkinson et al., 2018).

    Safety and Long-Term Use

    • Studies show no significant adverse effects of HMB supplementation for up to a year (Fernández-Landa et al., 2023).
    • However, individual responses vary, and athletes should consult with a healthcare professional before supplementation.

    Conclusion: Is HMB Worth It for Athletes?

    Who Benefits Most from HMB?

    ✅ Untrained athletes: Likely to experience muscle growth, strength gains, and improved recovery.
    ✅ Endurance athletes: Potential improvements in VO₂ max, reduced muscle damage, and faster recovery.
    ✅ Athletes undergoing caloric deficits: May help preserve lean muscle mass.

    Who May Not Benefit?

    ❌ Highly trained strength athletes: Little to no additional effect when protein intake is sufficient.
    ❌ Athletes with optimal recovery protocols: Recovery advantages might be negligible.

    Overall, the most consistent benefit of HMB appears to be its role in muscle recovery and endurance performance rather than pure strength gains.

    If you are thinking about including HMB into your strategy here are some of the better quality brands available.

  • Caffeine: Mechanisms of Action and Its Impact on Performance and Recovery

    Introduction

    Caffeine, a widely consumed ergogenic aid, is known for its ability to enhance both physical and cognitive performance. Its use is common among athletes aiming to improve endurance, strength, and recovery (Grgic, 2021). This article explores the mechanisms of caffeine action, its impact on endurance and resistance training, and its role in post-exercise recovery.

    Mechanisms of Action

    Caffeine exerts its effects through several key physiological mechanisms:

    Adenosine Receptor Antagonism:

    Caffeine blocks adenosine receptors (A1 and A2A) in the central nervous system, reducing fatigue perception and enhancing neurotransmitter release, particularly dopamine and norepinephrine (Ferreira, da Silva and Bueno, 2021).

    Calcium Mobilization:

    Caffeine increases calcium release from the sarcoplasmic reticulum in muscle cells, leading to enhanced muscle contraction and improved force production (Grgic, 2021).

    Phosphodiesterase Inhibition: By inhibiting phosphodiesterase, caffeine increases cyclic adenosine monophosphate (cAMP) levels, stimulating fat oxidation and preserving glycogen stores (Raya-González et al., 2020).

    Impact on Endurance Performance

    Caffeine is well-documented to improve endurance exercise performance by delaying fatigue and increasing time to exhaustion. Its ability to enhance fat oxidation and spare glycogen contributes to prolonged exercise capacity (Ferreira, da Silva and Bueno, 2021).

    Impact on Resistance Training

    Caffeine also has notable effects on resistance training:

    Muscular Strength:

    Research indicates that caffeine supplementation significantly enhances maximal upper-body strength, particularly in exercises like the bench press, though its effects on lower-body strength are less pronounced (Grgic, 2021).

    Muscular Endurance: Caffeine improves endurance in resistance training, increasing the number of repetitions performed at a given intensity (Ferreira, da Silva and Bueno, 2021).

    Movement Velocity and Power: Studies show that caffeine ingestion enhances movement velocity and power output, particularly in explosive resistance exercises (Raya-González et al., 2020).

    Impact on Recovery

    Caffeine’s influence on recovery is multifaceted:

    Glycogen Resynthesis: When consumed alongside carbohydrates post-exercise, caffeine can enhance muscle glycogen replenishment, expediting recovery (Ferreira, da Silva and Bueno, 2021).

    Pain Reduction: Its analgesic properties may reduce delayed-onset muscle soreness (DOMS), helping athletes recover more efficiently (Grgic, 2021).

    Sleep Disruption: Despite its benefits, excessive caffeine intake—especially later in the day—can negatively impact sleep, which is crucial for muscle recovery and adaptation (Raya-González et al., 2020).

    Conclusion

    Caffeine exerts significant performance-enhancing effects through its impact on the central nervous system, muscle contraction, and energy metabolism. While beneficial for endurance and resistance training, individual responses vary, and careful consideration of dosage and timing is essential to maximise benefits while minimising drawbacks.

  • How the body reacts to Glucose/Glycogen availability

    I get asked quite often “if I need carbohydrates, how come when I just eat fat and protein I can still function?”

    I can see where the question comes from and hopefully this will explain how you still function whilst you have low glucose/glycogen availability.

    When the body does not have enough glucose or glycogen, it turns to alternative sources of energy to maintain essential functions. Here’s how it adapts:

    1. Gluconeogenesis (Converting Non-Carbohydrates to Glucose)

    The body can produce glucose from non-carbohydrate sources through a process called gluconeogenesis, primarily in the liver (and to a lesser extent, the kidneys). The key substrates for gluconeogenesis include:

    • Amino Acids (from Protein Breakdown):
      • If glucose is scarce, the body starts breaking down muscle protein into amino acids like alanine and glutamine, which are then converted into glucose.
      • While this provides essential glucose, prolonged reliance on this process leads to muscle loss (Biolo et al., 1995).
    • Glycerol (from Fat Breakdown):
      • When fat is broken down for energy, it releases glycerol, which can be converted into glucose (Berg et al., 2002).
      • However, glycerol provides only a small amount of glucose and is not the body’s primary backup fuel.
    • Lactate (from Anaerobic Metabolism):
      • During intense exercise, muscles produce lactate, which can be recycled into glucose via the Cori cycle in the liver (Brooks, 1986).

    2. Ketogenesis (Using Fats for Energy)

    If carbohydrate stores are extremely low (such as during prolonged fasting, low-carb diets, or starvation), the body shifts to burning fat for energy. This process, called ketogenesis, occurs in the liver and produces ketone bodies, including:

    • Beta-hydroxybutyrate (BHB)
    • Acetoacetate
    • Acetone

    Ketones serve as an alternative fuel for the brain, muscles, and other tissues, reducing the reliance on glucose. This adaptation is the basis of ketogenic diets.

    3. Fat Oxidation (Using Fatty Acids for Energy)

    Most tissues (except the brain and red blood cells) can use fatty acids directly for energy through beta-oxidation in the mitochondria. However, fatty acids cannot be converted into glucose, which is why the body still needs some glucose production from protein and glycerol (Havel, 2005).

    Conclusion: The Body’s Adaptation to Low Glucose

    • Short-term (hours to a day) → Uses glycogen stores.
    • Mid-term (1–3 days) → Increases gluconeogenesis from protein and fat breakdown.
    • Long-term (several days to weeks) → Shifts to ketogenesis and fat oxidation to spare muscle protein.

    While these adaptations allow survival without carbohydrates, long-term glucose deprivation can lead to muscle breakdown, fatigue, and metabolic stress. Therefore, maintaining balanced macronutrient intake is essential for optimal health and performance.

    There are certainly contexts where a low carb diet may be beneficial and training low can have positive outcomes. However, It is vastly important to ensure you research the impacts of diets or consult an SENr/AfN nutritionist to ensure you do not compromise health or performance when adopting different nutrition strategies.

  • Turmeric in Exercise Recovery: What does science suggest

    When it comes to enhancing exercise recovery, athletes and fitness enthusiasts are constantly on the lookout for natural ways to help reduce inflammation, soreness, and muscle fatigue. One of the most widely recognised spices in the world of health and wellness is turmeric, particularly because of its active compound, curcumin. But can this golden spice really help with recovery after exercise?

    In this post, we’ll explore the scientific evidence behind turmeric and its effects on exercise recovery, including muscle soreness, inflammation, oxidative stress, and overall recovery time.

    What Is Turmeric?

    Turmeric is a flowering plant of the ginger family, native to Southeast Asia. It has been used for centuries in traditional medicine, particularly in Ayurvedic and Chinese medicine, for its anti-inflammatory and antioxidant properties. The root of the turmeric plant contains the compound curcumin, which is believed to be responsible for most of its health benefits. Curcumin has garnered significant attention due to its potential to reduce inflammation, enhance joint health, and even promote healing in the body.

    The Role of Inflammation in Exercise Recovery

    Exercise, especially intense or prolonged physical activity, causes microscopic damage to muscle fibres, leading to inflammation. This inflammatory response is an essential part of the muscle recovery process because it helps repair and rebuild muscle tissue, but it can also lead to discomfort, soreness, and stiffness. While inflammation is a necessary response to exercise, excessive inflammation can impair recovery and lead to conditions like delayed onset muscle soreness (DOMS).

    Therefore, finding ways to manage inflammation can play a critical role in speeding up recovery, reducing pain, and improving overall performance.

    How Turmeric Affects Exercise Recovery

    1. Reducing Inflammation and Muscle Soreness

    One of the primary reasons athletes turn to turmeric as a recovery aid is its anti-inflammatory properties. Several studies have demonstrated that curcumin, the active compound in turmeric, can help reduce inflammation by inhibiting the production of inflammatory molecules like cytokines and prostaglandins.

    Jain et al. (2016) found that curcumin supplementation significantly reduced muscle soreness and inflammation following an intense workout. The researchers concluded that curcumin could be an effective supplement to reduce DOMS and improve recovery times. Similarly, a study by McFarlin et al. (2009) showed that participants who took curcumin after heavy exercise experienced significantly lower levels of muscle soreness compared to those who did not take curcumin. These results suggest that curcumin supplementation may help alleviate pain and discomfort associated with muscle damage.

    2. Reducing Oxidative Stress

    Exercise, especially high-intensity training, can lead to an increase in oxidative stress, which occurs when there’s an imbalance between free radicals and antioxidants in the body. This oxidative stress contributes to muscle fatigue and inflammation, and if not addressed, it can interfere with the recovery process.

    Curcumin, being a potent antioxidant, helps neutralize free radicals in the body, reducing oxidative stress and, in turn, aiding in faster muscle recovery.

    A study published by Smith et al. (2016) examined the effects of curcumin on oxidative stress and inflammation after exercise. The study found that curcumin supplementation significantly reduced markers of oxidative stress and inflammation in athletes, suggesting it could play a role in promoting post-exercise recovery.

    3. Promoting Joint Health and Reducing Pain

    Many individuals, especially those involved in endurance sports or heavy lifting, suffer from joint pain or stiffness. The anti-inflammatory properties of curcumin extend beyond muscles to joints, where it has been shown to alleviate pain and improve joint function.

    A study in the Journal of Medicinal Food by Mishra et al. (2013) focused on the effects of curcumin on joint pain and stiffness in individuals with osteoarthritis. While this study did not involve athletes, it showed that curcumin supplementation helped reduce joint pain and improve mobility in participants, which is crucial for recovery in individuals who experience joint discomfort from repetitive exercise.

    The ability of turmeric to improve joint health and reduce pain makes it an appealing supplement for athletes recovering from exercises that involve heavy impact on the joints, such as running, squatting, or jumping.

    4. Speeding Up Muscle Recovery

    In addition to reducing inflammation and oxidative stress, curcumin may also enhance the overall muscle recovery process. A study published by Jain et al. (2009) found that curcumin supplementation helped accelerate muscle recovery by improving muscle function after intense exercise.

    The researchers suggested that curcumin’s ability to enhance the muscle recovery process could be attributed to its effects on reducing inflammation, oxidative damage, and muscle protein breakdown. Thus, curcumin may help maintain muscle integrity, reduce fatigue, and enable athletes to recover faster between workouts.

    How to Incorporate Turmeric into Your Recovery Routine

    Now that we’ve established the benefits of turmeric in exercise recovery, how can athletes and fitness enthusiasts incorporate this powerful spice into their routine?

    Here are a few ways to use turmeric for post-exercise recovery:

    • Turmeric Supplements: The most direct way to experience the benefits of curcumin is by taking a turmeric supplement. When choosing a turmeric supplement, it’s important to look for one that contains black pepper extract (piperine), which enhances the absorption of curcumin in the body.
    • Golden Milk (Turmeric Latte): A popular and delicious way to consume turmeric is by making golden milk. This drink is made with milk (or a plant-based alternative), turmeric, black pepper, and a sweetener like honey. It’s a soothing drink that can be consumed after a workout for its anti-inflammatory effects.
    • Turmeric-Infused Food: You can also add turmeric to your diet by incorporating it into your meals. Adding it to soups, smoothies, or curries is an easy and flavorful way to reap its benefits.
    • Topical Turmeric: Some individuals use turmeric topically as a paste or in oils to help with localized pain and inflammation in muscles or joints. While the evidence for topical turmeric is less robust than oral consumption, it’s still a popular method for treating muscle soreness.

    Dosage and Considerations

    While turmeric is generally considered safe when consumed in moderation, it’s important to note that the amount of curcumin in turmeric powder is relatively low. Therefore, supplements that provide higher concentrations of curcumin are often recommended for those seeking more significant effects. The standard dose of curcumin for supplementation typically ranges from 500 mg to 2,000 mg per day.

    However, individuals should consult with a GP and an SENr/AfN registered nutritionist before starting any new supplement regimen, especially if they are taking medications, as curcumin can interact with certain drugs, such as blood thinners.

    Final Thoughts

    Turmeric, and specifically its active compound curcumin, shows great promise in supporting exercise recovery through its anti-inflammatory, antioxidant, and muscle-repairing properties. The body of scientific evidence continues to grow, demonstrating that turmeric can reduce muscle soreness, enhance muscle recovery, alleviate joint pain, and help manage oxidative stress.

    Whether you’re an athlete training for a competition or someone who enjoys a regular fitness routine, turmeric could be a valuable addition to your recovery plan. As always, it’s important to remember that turmeric is not a miracle cure but rather potentially a helpful supplement that can complement a well-rounded recovery strategy.

  • Understand HMB, Benefits, Mechanisms and Safety

    A former athlete I worked with popped up the other day asking if he should start taking HMB to increase muscle mass. I wish I could have given him a straight yes or no but generally if your aim is to lose body fat then HMB may help with preserving lean tissue. However, research is far from definitive in support of its efficacy.

    Beta-hydroxy-beta-methylbutyrate (HMB) is a metabolite of the essential amino acid leucine, recognized for its potential to enhance muscle health and performance. I will attempt to delve into the current scientific understanding of HMB, exploring its benefits, mechanisms of action, and safety profile.

    Benefits of HMB Supplementation

    1. Muscle Mass and Strength Enhancement

    Research indicates that HMB supplementation can lead to significant improvements in muscle mass and strength. An umbrella review of meta-analyses by Bideshki et al. (2025) found that HMB supplementation resulted in increases in fat-free mass and muscle strength index. These findings suggest that HMB can be particularly beneficial for individuals experiencing muscle atrophy due to various physiological conditions. 

    2. Attenuation of Muscle Loss in Clinical Conditions

    Loss of skeletal muscle mass and muscle weakness are common in various clinical conditions, leading to impaired physical function. A systematic review and meta-analysis by Rowlands et al. (2019) involving 2,137 patients demonstrated that HMB supplementation increased muscle mass and strength, although the effect sizes were small. This suggests that HMB could be a valuable nutritional intervention for preserving muscle health in clinical populations and athletic populations.

    3. Reduction of Exercise-Induced Muscle Damage

    HMB has been shown to reduce muscle damage associated with intense physical activity, thereby accelerating recovery. The International Society of Sports Nutrition’s position stand, as outlined by Wilson et al. (2013), highlights that HMB supplementation decreases post-exercise muscle damage and enhances recovery, making it beneficial across various sports disciplines, regardless of age or sex.  

    Mechanisms of Action

    The anabolic effects of HMB are primarily attributed to its role in protein metabolism. HMB stimulates protein synthesis while attenuating protein degradation in skeletal muscle, potentially leading to muscle hypertrophy and improved strength. Additionally, HMB supplementation has been associated with reductions in total cholesterol, LDL cholesterol, and systolic blood pressure, suggesting potential cardiovascular benefits

    Safety and Dosage

    HMB supplementation is generally considered safe for consumption. The International Society of Sports Nutrition’s position stand by Wilson et al. (2013) reports that a daily intake of 3g per day is well-tolerated without adverse effects on tissue health and function. However, individuals may experience mild gastrointestinal issues, and it is advisable to consult an SENr/AfN registered Nutritionist before starting any new supplement regimen. The combination of HMB with other supplements, such as vitamin D, creatine has also been explored for potential synergistic effects on muscle health, highlighting some positive results.

    Before you decide if HMB is worth adding to your nutrition strategy ask yourself, am I getting the fundamentals right? I.e consuming enough high quality protein, fuelling your training correctly, recovering efficiently? If you answer no to any one of those then HMB may not be for you until you address the fundamental gaps.

    Conclusion

    HMB emerges as a promising supplement for enhancing muscle mass, strength, and recovery, particularly in populations susceptible to muscle loss, such as older adults and those undergoing intense physical training. Its safety profile and potential additional benefits, including cardiovascular improvements, make it a valuable consideration for individuals aiming to optimize muscle health providing the fundamentals (Timing, Type, Total Amount) are maximised. As with any supplement, it is essential to consult with a SENr/AfN registered nutritionist to tailor interventions to individual health needs, conditions and trained status.

  • The Importance of Nutrition for Game Day Minus One: A Football Player’s Key to Peak Performance

    As the big game approaches, football players are focused on refining their skills, finalizing tactics, and psyching themselves up for the win. However, one key aspect that can often be overlooked is nutrition—specifically, how players fuel themselves in the day leading up to the game. Nutrition on “game day minus one” (the day before the match) plays a crucial role in ensuring that athletes are physically prepared to perform at their peak. This blog post will explore why nutrition on the day before the game matters and provide evidence-based strategies for soccer players to optimise their energy, hydration, and recovery.

    Why Nutrition on Game Day Minus One Matters

    The human body operates as a finely tuned machine, and much like any machine, it requires the right fuel to function at its best. The day before a soccer match, players are looking to maximise glycogen stores (the body’s stored form of carbohydrate), maintain hydration levels, and promote recovery from previous training sessions.

    Here’s why nutrition on the day before the match is crucial:

    1. Glycogen Storage for Endurance Glycogen, the primary source of energy for athletes during high-intensity exercise, is stored in the muscles and liver. Football, with its high intensity, requires significant energy expenditure, especially during sprints, changes in direction, and bursts of activity. Ensuring that the body has sufficient glycogen stores is essential for endurance, focus, and strength on the field. Research suggests that carbohydrate loading, or increasing carbohydrate intake in the 24-48 hours prior to an event, enhances performance in endurance sports like soccer (Jeukendrup & Killer, 2010). On game day minus one, athletes should aim to consume complex carbohydrates like whole grains, pasta, rice, and potatoes, which provide a slow and sustained release of energy.
    2. Hydration for Optimal Performance Hydration is another pivotal factor in maximising performance. Dehydration can lead to decreased physical performance, reduced cognitive function, and an increased risk of injury. Studies show that even mild dehydration can impair performance, especially in sports that involve aerobic activity and intermittent sprints, such as soccer (Maughan & Shirreffs, 2010). On the day before the game, players should focus on staying hydrated throughout the day. A good rule of thumb is to drink water consistently throughout the day, starting early in the morning and continuing until evening. For some athletes, electrolyte-enhanced beverages may be beneficial, especially if training sessions leading up to the game have been intense.
    3. Promoting Recovery and Reducing Inflammation The training sessions leading up to the game can leave muscles fatigued and inflamed. Proper nutrition supports muscle recovery and minimises inflammation, helping players feel fresh and strong on match day. Protein, in particular, is essential for muscle repair, and it should be consumed at regular intervals throughout the day. A balanced intake of protein and fats is key for recovery. Sources of high-quality protein include whey, chicken, turkey, lean beef, fish, eggs, and plant-based options like tofu and lentils. Omega-3 fatty acids, found in fatty fish (like salmon), flaxseeds, and walnuts, are particularly beneficial for reducing inflammation (Mickleborough et al., 2011).
    4. Mental Focus and Cognitive Function A player’s mental clarity and focus are just as important as their physical condition when it comes to performing well on game day. The foods consumed the day before can influence cognitive function, decision-making speed, and focus. Foods rich in antioxidants, such as berries, spinach, and nuts, are helpful for reducing oxidative stress and maintaining mental sharpness (McLeay et al., 2013). Additionally, vitamin B-rich foods, such as whole grains and leafy vegetables, play a key role in the nervous system’s function.

    Practical Tips for Nutrition on Game Day Minus One

    Breakfast: A balanced breakfast should focus on providing carbohydrates, moderate protein, and a small amount of healthy fats. An example could be oatmeal topped with fruit, nuts, and a scoop of protein powder or Greek yogurt.

    Lunch: This meal should aim to increase glycogen stores further. A whole grain sandwich or wrap with lean protein (chicken or turkey), vegetables, and a side of fruit or a whole grain salad is a great option.

    Dinner: The final meal of the day should still prioritize carbohydrates, but with a slight emphasis on protein to aid recovery. A plate of whole grain pasta with lean protein (such as chicken) and a tomato-based sauce, alongside a large serving of vegetables, would provide a good balance.

    Snacks: Snacks throughout the day should be light but effective. A small bowl of mixed nuts, a banana with almond butter, or whole-grain crackers with cheese can maintain energy levels.

    Hydration: Drink plenty of water throughout the day. A good target is 3-4 liters for an average adult male, adjusting based on the player’s size, activity level, and environmental conditions.

    Foods to Avoid on Game Day Minus One

    While focusing on nutrition, it is just as important to avoid foods that may hinder performance. Players should steer clear of foods high in refined sugars or overly fatty foods, as they can cause blood sugar fluctuations and sluggishness. Additionally, heavy, rich foods (like greasy fast food) may lead to discomfort or gastrointestinal issues on match day.

    Conclusion

    Nutrition on game day minus one is a powerful tool that can directly influence a soccer player’s performance. By focusing on proper glycogen storage, hydration, recovery, and cognitive function, athletes can ensure that they are ready to perform at their best when the whistle blows. With the right strategies and meal planning, football players can fuel their bodies for success and give themselves the best possible chance of performing to their best.

  • Contraceptives and Weight Gain in Women: What Does the Science Say?

    Introduction

    The relationship between contraceptive use and weight gain has been a topic of debate for decades. Many women report weight changes after starting hormonal contraceptives, but is there scientific evidence to support this? This blog post reviews the current literature on how different types of contraceptives may influence body weight and composition.

    Types of Contraceptives and Their Potential Impact on Weight

    1. Combined Oral Contraceptives (COCs)

    COCs contain both estrogen and progestin and are one of the most commonly used contraceptive methods. Early versions of the pill contained high doses of estrogen, which were linked to water retention and weight gain (Lopez et al., 2016). However, modern low-dose formulations appear to have minimal effects on weight. A Cochrane review analyzing 49 trials found no significant evidence that COCs cause clinically meaningful weight gain (Lopez et al., 2016).

    2. Progestin-Only Pills (POPs)

    Progestin-only pills (also called the “mini-pill”) are sometimes preferred for women who cannot take estrogen. Limited evidence suggests that POPs do not significantly contribute to weight gain. However, some studies report increased appetite as a side effect, which could indirectly influence weight (Berenson et al., 2009).

    3. Injectable Contraceptives (Depo-Provera)

    Depot medroxyprogesterone acetate (DMPA), commonly known as Depo-Provera, has the strongest link to weight gain. Studies show that women using DMPA for a year or longer tend to gain an average of 2–3 kg, with some individuals experiencing even greater increases (Berenson et al., 2009). This weight gain is likely due to increased appetite and fat accumulation rather than water retention.

    4. Hormonal Implants and IUDs

    Implants (e.g., Nexplanon) and hormonal intrauterine devices (IUDs) release progestin over an extended period. Some research indicates that implants may lead to modest weight gain, whereas hormonal IUDs generally do not cause significant changes (Modesto et al., 2015). However, individual responses vary.

    5. Non-Hormonal Contraceptives

    Barrier methods (e.g., condoms, diaphragms) and copper IUDs do not influence hormones and therefore do not contribute to weight changes.

    Potential Mechanisms Behind Contraceptive-Related Weight Gain

    Several theories explain why some women experience weight gain while using hormonal contraceptives:

    • Increased appetite: Some progestins can stimulate appetite, leading to higher caloric intake.
    • Fluid retention: Estrogen can cause mild water retention, but this is typically temporary.
    • Changes in metabolism: Some evidence suggests that contraceptives might slightly alter metabolism and fat distribution.

    Individual Variability and Lifestyle Factors

    It’s important to recognize that weight gain while using contraceptives is not universal. Lifestyle factors, including diet, exercise, and genetics, play a significant role in weight changes. Some women may gain weight due to life-stage factors rather than the contraceptive itself.

    Conclusion

    The belief that all contraceptives cause weight gain is a common misconception. While some methods, particularly DMPA injections, have been linked to increased weight, others (such as COCs and IUDs) show minimal or no significant effects in most women. Women concerned about weight changes should discuss contraceptive options with their healthcare provider to find a method that best suits their needs.

  • Tart Cherry….a game changer for athletes?

    I thought about this after being asked if tart cherry is worth it….in my opinion based on the research available i think it certainly has a place in the athletic world. However, I think the context and the correct protocol are vital……A single dose post training may not be enough. Hopefully after reading this you may be best equipped to include tart cherry into your nutrition strategy.

    Tart Cherry for Performance and Recovery: A Science-Backed Approach?

    Athletes and fitness enthusiasts are constantly seeking natural ways to enhance performance and accelerate recovery. One food that has gained attention in recent years is tart cherry (Prunus cerasus). Rich in antioxidants, polyphenols, and anthocyanins, tart cherry has been studied for its potential benefits in muscle recovery, inflammation reduction, and overall exercise performance. This post explores the science behind tart cherry supplementation and its implications for athletic performance and recovery.

    The Science Behind Tart Cherry

    Tart cherries, particularly Montmorency cherries, contain high levels of anthocyanins, which possess potent anti-inflammatory and antioxidant properties (Bell et al., 2014). These bioactive compounds help mitigate oxidative stress and muscle damage caused by intense exercise. The consumption of tart cherry juice or supplements has been linked to reductions in markers of muscle damage, such as creatine kinase (CK) and lactate dehydrogenase (LDH), following strenuous exercise (Connolly et al., 2006).

    Performance Enhancement

    Research suggests that tart cherry supplementation can enhance endurance performance. A study by Levers et al. (2016) found that athletes who consumed tart cherry powder experienced improved aerobic endurance, reduced muscle soreness, and increased time to exhaustion compared to a placebo group. The potential mechanisms include improved blood flow, reduced oxidative stress, and enhanced mitochondrial function.

    Additionally, tart cherry has been shown to reduce muscle pain and soreness after high-intensity exercise. In a study by Howatson et al. (2010), marathon runners who consumed tart cherry juice experienced significantly less post-race muscle pain compared to those who did not. This suggests that tart cherry may support better performance by minimizing exercise-induced muscle damage and inflammation.

    Accelerated Recovery and Reduced Inflammation

    One of the key benefits of tart cherry for athletes is its ability to speed up muscle recovery. A study by Bowtell et al. (2011) demonstrated that tart cherry supplementation reduced muscle strength loss and improved recovery in well-trained individuals. The anti-inflammatory properties of tart cherry are particularly beneficial in reducing delayed onset muscle soreness (DOMS) and facilitating a quicker return to training.

    Moreover, tart cherry has been shown to positively influence sleep quality, which is crucial for recovery. The natural melatonin content in tart cherries may help regulate sleep cycles and improve overall sleep duration and quality (Losso et al., 2018).

    How to Incorporate Tart Cherry Into Your Routine

    For athletes and active individuals looking to incorporate tart cherry into their regimen, research suggests the following guidelines:

    • Tart Cherry Juice: Consuming 8–12 ounces (240–355 mL) of tart cherry juice twice daily for 4–7 days before and after intense exercise can optimize recovery benefits (Howatson et al., 2010).
    • Tart Cherry Capsules/Powder: Taking 480 mg of tart cherry extract or powder daily has been found to provide similar benefits (Levers et al., 2016).
    • Whole Cherries: Eating fresh or dried tart cherries can also provide a natural source of beneficial compounds, although juice and extracts may offer more concentrated effects.

    Conclusion

    Tart cherry supplementation is a promising natural strategy for improving athletic performance, reducing muscle soreness, and accelerating recovery. The antioxidant and anti-inflammatory properties of tart cherries have been well-documented in scientific literature, making them an excellent addition to an athlete’s nutrition plan. Whether consumed as juice, powder, or whole fruit, tart cherry offers a range of benefits that can support endurance, strength, and overall recovery.
