Step-by-Step Examples

28-Year-Old Female Moderate Activity Weight Loss

28-year-old female, 165 cm, 65 kg, exercising 3-5 days/week (multiplier 1.55).

Inputs: BMR: 1,380 kcal, Activity: Moderate (1.55)

Result: Maintenance: 2,139 kcal/day | Weight Loss: 1,639 kcal/day

TDEE = 1,380 × 1.55 = 2,139 kcal. A 500 kcal deficit targets 1,639 kcal/day for ~0.5 kg/week loss.

How to Use This Tool

Frequently Asked Questions

A cumulative deficit of approximately 3,500 kcal equals one pound of body fat, while a 7,700 kcal deficit corresponds to roughly one kilogram of body fat.

Total Daily Energy Expenditure (TDEE)

\text{TDEE} = \text{BMR} \times \text{Activity Factor}

TDEE = BMR × Activity Multiplier. Weight Loss Target = TDEE - 500 kcal/day (approx. 0.5 kg / 1 lb fat loss per week).
