About Weight Loss Science

1 kg fat ≈ 7700 calories → Safe loss: 0.5–1 kg/week

BMR (Harris-Benedict)
TDEE = BMR × Activity
Daily Intake = TDEE − Deficit

Formulas Used:

  • Male BMR: 88.362 + (13.397 × wt) + (4.799 × ht) − (5.677 × age)
  • Female BMR: 447.593 + (9.247 × wt) + (3.098 × ht) − (4.330 × age)
  • BMI: weight (kg) ÷ [height (m)]²
