These numbers are estimates from standard formulas (Mifflin-St Jeor) and are general educational information only — not medical advice. Your real needs vary with body composition, health and training history. Talk to a doctor or a registered dietitian before starting a new diet or training program, especially if you have a health condition. BMI is a rough screening number, not a diagnosis: muscular people often score high while carrying little body fat.
How to Read Your Numbers
BMR and TDEE
Your BMR is the energy your body burns at complete rest. Your TDEE adds your daily activity on top — that is your maintenance level: eat there and your weight stays put.
Macros
Protein builds and protects muscle, fats support hormones and health, and carbs fuel training. Your split above is a proven starting point — adjust in small steps as your results come in.
BMI
BMI is a rough screening number based on height and weight. It does not measure body fat directly, and muscular people often score high — use it as one signal among many, never the whole story.
