How this is calculated: BMR is computed using the Mifflin-St Jeor equation — the gold standard for clinical and sports nutrition. TDEE multiplies BMR by your activity factor. Protein is set at 2.0 g per kg of bodyweight (within the 1.5–3.3 g/kg evidence-based range for active adults), fat at 25% of total calories, with carbohydrates filling the remainder for training fuel.

Frequently Asked Questions

What is BMR — and why does it matter?

BMR (Basal Metabolic Rate) is the number of calories your body burns at complete rest just to keep you alive — heart beating, lungs breathing, cells repairing. It accounts for about 60-75% of your total daily calorie burn. Knowing your BMR is the foundation of every effective nutrition plan: too few calories and your body breaks down muscle and stalls progress; too many and fat gain creeps in. We calculate yours using the Mifflin-St Jeor equation, the gold standard used in sports nutrition research.

How is the calorie target calculated?

Three steps. First, BMR via Mifflin-St Jeor: (10 × weight kg) + (6.25 × height cm) – (5 × age) + 5 for men (−161 for women). Second, TDEE (total daily energy expenditure) by multiplying BMR by your activity factor — 1.2 for sedentary up to 1.9 for very active. Third, the goal adjustment: a ~400 kcal deficit for fat loss, maintenance for performance and health, or a ~300 kcal surplus for lean muscle gain. The result is your target daily intake.

How are the macros split?

Protein is anchored to bodyweight, never below 1.5 g per kg for any goal. For active hypertrophy (Build Muscle), we set protein at 2 g per pound (~4.4 g/kg) — the level used by elite strength athletes for maximal lean tissue gain. For fat loss we use 2.4 g/kg (high to preserve muscle in deficit). Maintenance sits at 1.8 g/kg for performance and recovery. Fat is set at 25% of total calories (essential for hormone health). Carbohydrates fill the remainder — your training fuel.
