            TDEE = BMR \times \text{Activity Factor (1.2 - 1.9)}
          

BMR calculated via Mifflin-St Jeor: 10W + 6.25H - 5A + S. Total Daily Energy Expenditure equals BMR multiplied by Physical Activity Level (PAL).

常见问题与详细解答 (FAQ)

What is the difference between BMR and TDEE?

BMR (Basal Metabolic Rate) is the calories burned at complete rest to maintain vital organ functions. TDEE (Total Daily Energy Expenditure) is total calories burned daily including movement, work, and exercise.

How large of a calorie deficit is recommended for safe fat loss?

A moderate deficit of 300 to 500 kcal/day is standard for sustainable fat loss of approximately 0.5 to 1 lb (0.25-0.5 kg) per week without compromising lean muscle mass.
