Frequently Asked Questions

Nutrition for active individuals requires a strategic approach that supports both training intensity and recovery. The foundation includes consuming adequate protein (1.2–2.0 grams per kilogram of body weight daily) to support muscle repair and development. Carbohydrates remain essential for energy, particularly around training windows, and should comprise 45–65% of total calorie intake depending on activity level.

Healthy fats are equally important, supporting hormone production and reducing inflammation. Focus on timing your meals appropriately—consuming carbohydrates and protein within 30–60 minutes after exercise optimises recovery. Hydration is non-negotiable; drink enough fluids throughout the day and during exercise to maintain performance and prevent fatigue.

Individual needs vary based on your specific sport, training frequency, body composition goals, and personal preferences. Working with the right nutritional resources helps you create a personalised approach that fits your lifestyle.

Protein requirements depend on your activity level, training goals, and body weight. For sedentary adults, the recommended dietary allowance is 0.8 grams per kilogram of body weight. However, those engaged in regular exercise benefit from higher intake.

Endurance athletes typically need 1.2–1.4 grams per kilogram, while strength and power athletes benefit from 1.6–2.0 grams per kilogram daily. If you weigh 70 kilograms and train with weights, you'd aim for approximately 112–140 grams of protein daily, spread across meals.

Distribute protein intake throughout the day—consuming 20–40 grams per meal optimises muscle protein synthesis. Quality sources include lean meats, fish, eggs, dairy, legumes, nuts, and seeds. Plant-based athletes can meet their needs through varied combinations of legumes, whole grains, nuts, and seeds.

Your exact needs may vary, so consider adjusting based on your progress, energy levels, and how your body responds to training.

Pre-workout nutrition should be consumed 1–3 hours before exercise and focus on easily digestible carbohydrates with moderate protein. Examples include toast with almond butter, a banana with yoghurt, oatmeal with berries, or rice cakes with honey. This provides energy without causing digestive discomfort.

Post-workout nutrition is crucial for recovery. Within 30–60 minutes after training, consume a combination of carbohydrates and protein to replenish glycogen stores and begin muscle repair. Good options include a protein smoothie with fruit, chicken with rice and vegetables, Greek yoghurt with granola, or a turkey sandwich on whole grain bread.

The exact timing matters less for longer-term progress than overall daily nutrition, but this window optimises immediate recovery. Hydration is equally important—drink fluids containing electrolytes if your session lasted over 60 minutes or was particularly intense.

Pay attention to how different foods make you feel during exercise. Some athletes thrive with a meal 2 hours before training, while others prefer just a small snack 30 minutes beforehand.

Hydration is absolutely critical for performance, safety, and recovery. Even mild dehydration (2% loss of body weight) reduces exercise capacity, increases perceived effort, and impairs thermoregulation. Losing more than 3% of body weight through sweat significantly compromises performance and health.

Drink fluids consistently throughout the day, not just during exercise. A practical guideline is to drink enough that your urine remains pale yellow. During exercise lasting less than 60 minutes, water alone is sufficient. For longer sessions, especially in warm conditions, beverages containing carbohydrates (6–8%) and electrolytes (sodium) enhance fluid absorption and maintain performance.

Drink approximately 400–800 millilitres (14–27 fluid ounces) of fluid every hour of intense exercise, adjusted for individual sweat rate, environmental conditions, and sport-specific factors. After exercise, drink approximately 150% of fluid lost over 4–6 hours to fully rehydrate, as some fluid is lost through sweat and urine.

Individual hydration needs vary significantly based on genetics, fitness level, acclimatisation, and environmental conditions. Monitor your weight before and after training to estimate sweat rate and adjust fluid intake accordingly.

Nutrition is one pillar of athletic success, but not the only one. Optimal performance requires a combination of proper training, adequate recovery, sleep quality, stress management, and sound nutrition. Think of it as interconnected systems: you can't ignore any single component and expect maximum results.

Good nutrition supports everything else. It provides energy for quality training, facilitates recovery between sessions, reduces injury risk, and optimises body composition. However, without consistent, well-designed training, proper nutrition alone won't produce athletic gains.

Conversely, the most brilliant training programme is undermined by poor nutrition and inadequate sleep. The synergy between these factors matters most. Research consistently shows that athletes who prioritise nutrition alongside training see better progress in strength, endurance, speed, and body composition compared to those who neglect the nutritional component.

Start by establishing solid fundamentals: consume enough calories to support your activity, eat adequate protein, hydrate consistently, and time nutrients around training. This foundation, combined with intelligent training, produces substantial improvements.

Macronutrients are the three primary nutrients your body needs in large quantities: carbohydrates, protein, and fat. Each plays a distinct role in supporting athletic performance and health.

Carbohydrates are the primary fuel source for intense exercise, stored as muscle glycogen. Protein provides amino acids needed for muscle repair, enzyme production, and immune function. Fats support hormone production, absorb fat-soluble vitamins, and provide concentrated energy (9 calories per gram versus 4 for carbohydrates and protein).

The optimal ratio of macronutrients depends on your specific sport and training goals. Endurance athletes often benefit from higher carbohydrate intake (55–70% of calories), while strength athletes may emphasise protein intake. However, balance matters—completely eliminating any macronutrient is counterproductive.

Rather than obsessing over precise percentages, focus on consuming whole foods, adequate total calories, sufficient protein, and nutrient-dense carbohydrates and fats. This approach naturally creates an appropriate macronutrient balance for most active individuals without requiring complex calculations.

Endurance activities lasting over 90 minutes demand specific fuelling strategies to maintain performance and prevent fatigue. Your muscles store approximately 90 minutes' worth of glycogen at full capacity, making carbohydrate availability critical for longer efforts.

For activities lasting 60–90 minutes, a solid pre-exercise meal 2–3 hours beforehand, hydration, and a post-exercise meal are typically sufficient. For activities exceeding 90 minutes, consume 30–60 grams of carbohydrates per hour during exercise through sports drinks, gels, energy bars, or real food like bananas and dates. This quantity is sufficient for most endurance activities and reduces gastrointestinal distress compared to overeating.

Experiment during training, never during competition. Your gut needs adaptation to absorb fuel efficiently during exercise. Start with small quantities and gradually increase as your digestive system adapts.

Post-exercise recovery is equally important. Consume carbohydrates and protein within 30–60 minutes to replenish glycogen stores and begin muscle repair. For events lasting several hours, consume 1.2–1.5 grams of carbohydrates per kilogram of body weight with protein within the first 4 hours after finishing.

Micronutrients—vitamins and minerals—are crucial for energy production, muscle function, bone health, and immune defence. Key micronutrients for active individuals include iron (oxygen transport), calcium and vitamin D (bone health), magnesium (muscle function), and B vitamins (energy metabolism).

Iron is particularly important for endurance athletes, as it carries oxygen in the blood and within muscles. Women, vegetarians, and vegans should pay special attention to iron intake. Calcium and vitamin D support bone density, crucial for impact sports and long-term skeletal health. Antioxidants like vitamins C and E, and selenium help manage exercise-induced oxidative stress.

Most active individuals meet micronutrient needs through a varied whole-food diet emphasising fruits, vegetables, whole grains, legumes, nuts, seeds, and lean proteins. Deficiency is uncommon in well-nourished athletes, but certain groups (vegetarians, restricted-diet athletes, those in heavy training) may benefit from targeted attention.

Rather than supplementing every micronutrient, start by ensuring your diet includes a colourful variety of whole foods. This approach provides synergistic nutrients and compounds that supplements cannot replicate. If you suspect a specific deficiency, consider discussing assessment and targeted support with an appropriate nutrition professional.

Building muscle requires three key nutritional elements: adequate total calories, sufficient protein, and strategic carbohydrate and fat intake. Muscle growth occurs when you consistently consume enough energy to support training intensity plus the anabolic processes of building new tissue.

Protein intake is paramount—aim for 1.6–2.0 grams per kilogram of body weight daily, distributed across 4–5 meals. Consuming 20–40 grams of protein per meal optimises muscle protein synthesis. Prioritise complete protein sources containing all nine essential amino acids: meat, fish, eggs, dairy, or plant-based combinations.

Carbohydrates fuel intense training sessions and support recovery. Consume carbohydrates strategically around workouts to maximise training quality and recovery. Healthy fats support hormone production—don't restrict fat intake below 20% of total calories, as hormonal production suffers.

Progressive overload in training is equally essential; nutrition alone cannot build muscle without challenging workouts that create stimulus for growth. Combine intelligent training with consistent, protein-rich nutrition and adequate sleep for optimal muscle development.

Carbohydrates are the preferred fuel source for high-intensity exercise because they're efficiently converted to ATP (cellular energy) with less oxygen required compared to fats. Your muscles store glycogen (the storage form of glucose) in amounts sufficient for approximately 90 minutes of moderate-intensity exercise.

During intense training, adequate carbohydrate availability improves power output, speed, and training quality. Depletion of muscle glycogen increases perceived effort and decreases performance. For athletes training intensely more than once daily, consistent carbohydrate intake becomes critical for maintaining training quality across sessions.

Contrary to outdated "low-carb" myths, most athletes benefit from substantial carbohydrate intake. The exact amount depends on training intensity and duration—endurance athletes typically need 55–70% of calories from carbohydrates, while strength athletes may do well with 45–55%.

Focus on quality sources: oats, brown rice, whole grain bread, sweet potatoes, legumes, and fruits provide carbohydrates alongside fibre, vitamins, and minerals. These whole-food sources sustain energy better than refined alternatives and support overall health beyond just athletic performance.

Training cycles naturally vary in intensity, volume, and focus. Strategic nutrition adjustments optimise results for each phase while preventing burnout and overtraining.

During high-volume training phases (building endurance or strength base), increase total calorie intake to support increased work capacity and recovery demands. Emphasise carbohydrates for energy and protein for repair. During peak/competition phases with lower volume but higher intensity, maintain adequate calories and protein while potentially reducing overall volume to match the lower work demand. During deload or transition phases with reduced training, slightly reduce total calories to prevent unwanted weight gain while maintaining protein intake to preserve muscle.

The principle is matching calorie and macronutrient intake to training demands. Heavy training phases demand more total energy and carbohydrates; lighter phases need less. Protein intake remains consistently important throughout all phases for tissue repair and adaptation.

Rather than making dramatic changes, adjust gradually based on how you feel and perform. If training intensity increases but you feel constantly fatigued, increase carbohydrate and overall calorie intake. These adjustments need not be complex—often, simply eating more when training harder is sufficient.

The internet contains vast amounts of nutrition information—some evidence-based and valuable, some misleading or dangerously inaccurate. Distinguishing quality sources requires critical evaluation.

Prioritise sources from established sports nutrition organisations, peer-reviewed research, and reputable educational institutions. Websites ending in .org (universities and professional organisations) or peer-reviewed journals are generally more reliable than influencer blogs or marketing-driven sites. Be sceptical of sources making extreme claims, promoting expensive products as essential, or dismissing entire food groups.

Reliable platforms include international sports nutrition societies, government health departments, and university-affiliated resources. Books and articles by authors with formal qualifications in nutrition science tend to be more accurate than blog posts by self-proclaimed "gurus" with no credentials.

For personalised guidance matching your specific sport, body composition goals, and health factors, consult with appropriately qualified nutrition professionals. Basic principles—eating whole foods, consuming adequate protein, timing nutrients around training, and staying hydrated—are well-established and don't require expensive personalised plans. Use reliable information to build these fundamentals, then refine based on your individual experience and results.
