TDEE for Bodybuilding and Body Recomposition
Bodybuilding demands precise nutrition to build muscle while managing body fat. Your Total Daily Energy Expenditure (TDEE) is the starting point for every effective bodybuilding diet — whether you are bulking, cutting, or pursuing body recomposition. Our TDEE calculator for bodybuilding accounts for the high training volumes and elevated recovery demands that set strength athletes apart from the general population.
Enter your stats and activity level to get a personalised calorie target. From there, adjust your intake based on your current phase: a surplus of 200–400 calories for lean bulking, maintenance calories for recomposition, or a moderate deficit of 300–500 calories for contest prep and cutting.
Bulking vs Cutting vs Body Recomp
Traditional bodybuilding cycles between bulking (calorie surplus to maximise muscle growth) and cutting (calorie deficit to strip fat while preserving muscle). A lean bulk keeps the surplus small to minimise fat gain, while an aggressive bulk prioritises rapid weight gain at the cost of added body fat.
Body recomposition — simultaneously losing fat and gaining muscle — is possible for beginners, those returning after a break, and athletes with higher body fat percentages. It requires eating at or slightly below maintenance while keeping protein high (1.8–2.2 g per kg of body weight) and training with progressive overload.
Setting Macros for Bodybuilding
Once you know your TDEE, distribute your calories across macronutrients for optimal results. A common bodybuilding split is 40% protein, 30% carbohydrates, and 30% fat, though this varies by individual preference and training style. Protein intake is the most critical variable — research consistently shows that 1.6–2.2 g per kg of body weight supports maximal muscle protein synthesis.
Carbohydrates fuel training performance and recovery, so higher-carb approaches often suit high-volume programs. Fats should not drop below 0.5 g per kg to support hormone production. Use our calculator as your baseline, track your progress for 2–4 weeks, and adjust calories by 100–200 per day based on the scale and mirror.
