Frequently Asked Questions

The ideal macronutrient ratio for active individuals typically ranges from 40-50% carbohydrates, 25-35% protein, and 20-30% fats. However, this varies based on your specific activity type—endurance athletes may benefit from higher carbohydrate intake (50-60%), while strength trainers often thrive with increased protein (1.2-2.0g per kilogramme of body weight). The key is experimenting within these ranges to find what supports your energy levels, recovery, and performance goals. Individual factors like metabolism, training intensity, and body composition also play crucial roles in determining your optimal ratio.

Hydration needs depend on exercise duration, intensity, temperature, and individual sweat rate. A general guideline is to drink 400-800ml of fluid per hour of moderate to vigorous exercise. Start drinking early—don't wait until you feel thirsty, as thirst is often a delayed indicator of dehydration. For activities lasting under 60 minutes, water alone is sufficient. For longer sessions, consider beverages containing carbohydrates (6-8% solution) and electrolytes to maintain performance and aid absorption. Weigh yourself before and after exercise; a 2% loss indicates you need increased fluid intake.

Timing and composition of pre-workout meals depend on your workout intensity and duration. For substantial meals (400-600 calories), eat 3-4 hours before exercise. For moderate meals (200-300 calories), 2-3 hours is ideal. Light snacks (100-200 calories) work well 30-60 minutes before activity. Focus on easily digestible carbohydrates and moderate protein, with minimal fat and fibre to avoid digestive discomfort. Examples include: oatmeal with banana and honey (3 hours before), a rice cake with jam (1-2 hours before), or an energy bar 30 minutes prior. Listen to your body—some people perform better fasted, while others need fuel.

Post-workout nutrition is critical for recovery and adaptation. Within 30-60 minutes after exercise, aim to consume a combination of carbohydrates and protein to replenish glycogen stores and support muscle repair. A ratio of 3:1 or 4:1 (carbs to protein) is often recommended. For example, chocolate milk, a turkey sandwich, or Greek yoghurt with berries and granola all work well. This window of opportunity helps your body transition from a catabolic (breakdown) to an anabolic (building) state. Proper post-workout nutrition also reduces muscle soreness, improves recovery, and enhances adaptations to training stimulus.

Active individuals have elevated micronutrient needs due to increased metabolism and losses through sweat. Key micronutrients include: Iron (oxygen transport and energy production), Magnesium (muscle function and recovery), Calcium (bone health), Zinc (immune function and protein synthesis), and B vitamins (energy metabolism). Vitamin D is particularly important for bone health and immune function, especially in the UK where sun exposure is limited. Antioxidant vitamins C and E help manage exercise-induced oxidative stress. Rather than relying solely on supplements, prioritise whole foods—leafy greens, nuts, seeds, lean meats, and colourful vegetables provide these nutrients in bioavailable forms.

Different activities require tailored nutritional approaches. For endurance activities (running, cycling, swimming lasting over 90 minutes), prioritise carbohydrate loading 2-3 days before and fuel during the event with simple carbs. For strength training, ensure adequate protein intake (1.6-2.2g per kg body weight daily) distributed across meals, with moderate carbs to support intense sessions. HIIT workouts benefit from a balanced approach with good carbohydrate availability pre-workout and protein post-workout. For team sports, maintain consistent fuelling before and after, with electrolyte replacement during longer matches. Understanding your specific activity's energy system—aerobic, anaerobic, or mixed—helps optimise your nutrition strategy.

Absolutely. Many elite athletes thrive on plant-based diets when properly planned. The key is ensuring adequate protein intake from diverse sources—legumes, tofu, tempeh, seitan, nuts, seeds, and whole grains. Plant-based proteins are often lower in some amino acids, so combining different sources throughout the day ensures complete amino acid profiles. Pay special attention to iron (use vitamin C with plant sources to enhance absorption), vitamin B12 (supplement or fortified foods), omega-3 fatty acids (flaxseeds, chia seeds, walnuts), and zinc. Plan meals thoughtfully to meet caloric and micronutrient needs, and consider working with a sports nutritionist familiar with plant-based nutrition to optimise your approach.

Nutrition plays a significant role in injury prevention by supporting connective tissue strength, bone density, and immune function. Adequate protein ensures muscle and tendon repair and adaptation. Sufficient carbohydrates maintain glycogen levels, which impacts muscle coordination and injury risk. Minerals like calcium, magnesium, and phosphorus are essential for bone integrity. Antioxidants from fruits and vegetables help manage inflammation from training stress. Omega-3 fatty acids support joint health and reduce excessive inflammation. Proper hydration maintains disc and cartilage function. Additionally, maintaining energy availability (not under-fuelling chronically) supports hormonal balance essential for bone and muscle health. Consider nutrition as preventive medicine alongside your training programme.

Training periodisation requires corresponding nutritional adjustments. During high-intensity or high-volume phases, increase total energy intake and carbohydrate availability to support training demands and recovery. In lower-intensity phases, slightly reduce calories if body composition management is a goal, but maintain micronutrient density. Pre-competition phases may warrant specific carbohydrate loading strategies for endurance events. Off-season periods offer opportunities to refine body composition and address micronutrient gaps. Seasonal variations in food availability (summer produce versus winter storage foods) naturally offer different nutrient profiles—embrace local, seasonal foods for nutritional variety and sustainability. Listen to your body and adjust based on energy levels, recovery quality, and performance metrics.

Most active individuals can meet their nutritional needs through whole foods alone. However, supplements can be useful in specific situations: protein powder for convenience when meeting daily targets through food is impractical, creatine monohydrate for strength and power athletes (well-researched and safe), vitamin D in countries with limited sun exposure, and potentially iron or B12 for those with documented deficiencies or on restrictive diets. Sports drinks containing carbs and electrolytes are beneficial during prolonged exercise. Before considering any supplement, evaluate whether you've optimised whole-food nutrition first. Quality matters—choose products tested for purity and accurately labelled. When in doubt, consult evidence-based resources or nutrition professionals rather than marketing claims.

Balancing performance with body composition changes requires a nuanced approach. Underfuelling for extended periods impairs performance, recovery, and health. If pursuing body composition changes, do so gradually—a modest caloric deficit (300-500 kcal daily) allows continued training quality and muscle preservation. Prioritise protein intake throughout a deficit to preserve muscle mass. Include strength training to signal the body to maintain muscle tissue. Monitor how you feel—persistent fatigue, weakened performance, or mood changes suggest inadequate energy availability. For muscle gain, a modest caloric surplus (300-500 kcal daily) combined with consistent resistance training and adequate protein supports growth without excessive fat gain. Remember that performance improvements and sustainable body composition changes take time—patience and consistency matter more than extreme approaches.

Common mistakes include: under-fuelling (not eating enough to support training load), inconsistent protein intake (sporadic rather than distributed across meals), neglecting micronutrients in pursuit of macros, poor hydration timing, over-relying on supplements instead of whole foods, and ignoring individual variation (following generic plans without personalisation). Many athletes also skip pre-workout fuelling when needed, fail to refuel adequately post-workout, and don't adjust nutrition when training volume changes. Additionally, perfectionism around nutrition can become counterproductive—aiming for 80% consistency with sustainable, enjoyable food choices beats 100% compliance with restrictive approaches. Individual tolerance to different foods, timing preferences, and digestive capacity vary greatly, so experimentation based on your own experience matters more than rigid protocols.
