Frequently Asked Questions

The protein requirements for active individuals are substantially higher than the general population recommendation of 0.8g per kilogram of body weight. For those engaged in resistance training, endurance activities, or combined workouts, research supports intake between 1.6 to 2.2 grams per kilogram of body weight daily. For example, an 80kg athlete would require approximately 128–176g of protein per day, distributed across multiple meals. This elevated intake supports muscle protein synthesis, recovery, and adaptation to training stress. However, the exact requirement depends on training type (strength vs. endurance), age, sex, and overall energy balance. Our nutritional guidance emphasises quality protein sources, optimal timing, and distribution across the day to maximise the anabolic response to training.

Nutrient timing significantly impacts performance and recovery. Pre-exercise nutrition should be consumed 1–3 hours before activity, consisting of easily digestible carbohydrates with moderate protein and minimal fat and fibre to avoid gastrointestinal discomfort. Examples include oatmeal with banana, toast with jam, or a sports drink. For training lasting longer than 60 minutes, consuming carbohydrates during exercise (30–60g per hour) helps maintain blood glucose and delays fatigue. Post-exercise nutrition is equally crucial: within 30–120 minutes after training, consuming protein (20–40g) with carbohydrates (0.8–1.2g per kg body weight) stimulates muscle protein synthesis and replenishes glycogen stores. A simple post-workout meal might be Greek yoghurt with berries, a protein smoothie, or chicken with rice. The exact timing depends on individual tolerance, training intensity, and overall daily nutrition plan.

Carbohydrates are the primary fuel source for high-intensity exercise and endurance activities. The best choices include whole grains (brown rice, oats, wholemeal bread), legumes (lentils, beans, chickpeas), fruits (apples, bananas, berries), and starchy vegetables (sweet potatoes, quinoa). These foods provide sustained energy, fibre, and essential micronutrients. For immediate pre-workout energy, simpler carbohydrates like white rice, white bread, or sports drinks may be more appropriate to ensure rapid absorption. During intense training or competition, rapidly absorbed carbohydrates (sports gels, drinks, or dried fruit) become important. The quality and quantity should match the training phase: higher complex carbohydrates during general training, and strategic intake of simpler carbs around intense sessions. Individualising carbohydrate intake based on training load, duration, and personal tolerance is central to our nutritional recommendations.

Hydration is absolutely fundamental to athletic performance, thermoregulation, and safety. Even mild dehydration—losing just 2% of body weight in fluids—impairs cognitive function, reduces strength and endurance, and increases perceived effort. Active individuals should drink water consistently throughout the day, not just during exercise. For sessions lasting less than 60 minutes, plain water is typically sufficient. For longer or intense activities, sports drinks containing 6–8% carbohydrates and electrolytes (sodium, potassium) help maintain blood glucose, delay fatigue, and promote fluid retention. A practical hydration strategy involves drinking 400–800ml of fluid 2–3 hours before exercise, 200–300ml 15–20 minutes before starting, and 150–250ml every 15–20 minutes during activity, adjusting based on individual sweat rate and environmental conditions. Post-exercise rehydration should exceed fluid losses by about 50% to account for ongoing sweat and urine production. Our nutrition guidance emphasises individualised hydration plans based on sport, climate, and personal physiology.

Whole foods should always form the foundation of an athlete's nutrition. A well-planned diet that meets energy, protein, and micronutrient needs can support excellent performance without supplements. However, supplements can be beneficial in specific situations: when dietary needs cannot be met through food alone, when convenience is essential (post-workout protein shake), or when targeting specific adaptations (creatine for strength athletes). Evidence-supported supplements for active people include whey protein powder (convenience and cost-effectiveness), creatine monohydrate (for strength and power), beta-alanine (for high-intensity endurance), and caffeine (for endurance performance and alertness). Vitamin and mineral supplements may be warranted if deficiencies exist, such as iron supplementation for female athletes with low stores. Before adding any supplement, it is crucial to assess whether your current diet truly falls short and to verify the product's safety and quality. At Dietexpertpath, we emphasise food-first approaches, recommending supplements only when they address genuine nutritional gaps or performance goals supported by research.

Active individuals seeking to manage body weight must carefully balance energy intake with expenditure whilst maintaining performance and recovery. Excessive calorie restriction whilst training intensely can impair muscle maintenance, reduce training quality, compromise immune function, and slow recovery. A moderate calorie deficit of 300–500 calories below maintenance, combined with adequate protein (1.6–2.2g/kg) and maintained carbohydrate intake, supports gradual fat loss whilst preserving lean mass and performance. It is essential to monitor training intensity and wellbeing: if energy crashes or injury frequency increases, calorie reduction has likely been too aggressive. Conversely, those aiming to build muscle and strength require a modest calorie surplus (250–500 calories above maintenance) with sufficient protein and carbohydrates to support adaptation and recovery. The timing of meals, distribution of macronutrients across the day, and individual metabolic factors all influence outcomes. Our editorial approach emphasises sustainable, performance-supporting nutrition strategies rather than extreme restriction, recognising that the best nutrition plan is one an athlete can maintain long-term whilst continuing to thrive in their sport.

Beyond the major macronutrients, active individuals have elevated requirements for several micronutrients essential for energy production, oxygen transport, immune function, and muscle repair. Iron is critical for oxygen delivery to working muscles; female athletes and endurance athletes face heightened deficiency risk. Calcium and vitamin D support bone health, particularly important for athletes engaged in high-impact activities and those restricting calories. B vitamins (B6, B12, folate) facilitate energy metabolism and muscle protein synthesis. Magnesium supports muscle function and recovery; athletes often show lower levels due to increased urinary losses. Zinc plays a role in immune function and protein synthesis, and losses increase with intense training. Antioxidant micronutrients like vitamins C and E, selenium, and polyphenols help manage exercise-induced oxidative stress and inflammation. Sodium and potassium, lost through sweat, are critical for hydration and neuromuscular function. Rather than attempting isolated supplementation for each micronutrient, consuming a variety of whole foods—lean proteins, whole grains, colourful fruits and vegetables, nuts, seeds, and dairy or fortified alternatives—naturally provides the micronutrient density that active people require. Regular dietary assessment can identify specific deficiencies warranting targeted support.

Strength training and endurance training present distinct nutritional demands and adaptations. Strength athletes prioritise muscle protein synthesis and hypertrophy, requiring higher total protein intake (2.0–2.2g/kg), adequate energy for training intensity, and moderate to high carbohydrates to fuel explosive movements and maintain training volume. Energy timing around resistance sessions is important for maximising the anabolic window. Endurance athletes, conversely, depend heavily on carbohydrate availability to fuel prolonged activity, typically requiring 6–10g of carbohydrates per kilogram of body weight daily depending on training volume. Protein needs are still elevated (1.6–2.0g/kg) for muscle repair between sessions and prevention of excessive muscle breakdown. Endurance athletes often prioritise race fuelling strategies—learning to consume carbohydrates and fluids during lengthy efforts—and managing body weight for performance advantages. Combined training (concurrent strength and endurance) requires careful periodisation and nutrition planning to support adaptations to both modalities without excessive fatigue. Recovery nutrition, sleep, and overall energy balance are universally important, but the specific macronutrient ratios and meal timing strategies differ meaningfully between these training types. Understanding these distinctions allows for more precise and effective nutritional support of your individual training goals.

Rest days are crucial for recovery, adaptation, and injury prevention, and nutrition on these days should support these processes rather than mirror training days. Total energy intake should be somewhat reduced compared to heavy training days, as the daily energy expenditure is lower without structured exercise. However, protein intake should remain consistently elevated (1.6–2.2g/kg) to support ongoing muscle protein synthesis and tissue repair from previous training sessions. Carbohydrate intake can be moderately reduced, as the body's glycogen demand is lower without intense activity, though adequate amounts still support cognitive function and general wellbeing. Focus on nutrient-dense, whole foods: lean proteins, colourful vegetables and fruits, whole grains, healthy fats, and legumes. Rest days offer excellent opportunities to prepare nutritious meals, meal-prep for the coming training week, and experiment with new recipes from our collection. Hydration remains important, and gentle movement like walking or easy stretching can be incorporated. Sleep quality often improves with lower caffeine and better overall nutrition, so timing lighter meals earlier in the evening may be beneficial. The mental and physical recovery on rest days is as essential to long-term performance as the training itself, and appropriate nutrition facilitates this restoration.

Sleep is one of the most powerful recovery tools available to athletes, and nutrition plays a significant supporting role. Quality sleep depends partly on circadian rhythm regulation, which is influenced by melatonin production and light exposure, and certain foods can help support this. Tryptophan-rich foods (turkey, chicken, eggs, cheese, nuts, seeds) support serotonin and melatonin synthesis. Magnesium, abundant in leafy greens, nuts, seeds, and whole grains, promotes relaxation and sleep quality. Complex carbohydrates consumed a few hours before bed can increase tryptophan availability to the brain, supporting better sleep onset. Conversely, avoid large, heavy meals close to bedtime—allow 2–3 hours of digestion time. Limit caffeine after early afternoon, as sensitivity varies individually but can significantly disrupt sleep architecture. Alcohol might seem to aid sleep initiation, but it impairs sleep quality and recovery, particularly for athletes. Consistent meal timing, including a regular dinner schedule, helps synchronise circadian rhythm and supports hormonal balance. Adequate daytime hydration—whilst limiting fluids immediately before bed—supports both sleep quality and overnight recovery processes. Creating a consistent evening nutrition routine, perhaps with a light herbal tea or warm milk, can signal to your body that sleep is approaching, complementing other sleep hygiene practices.
