Common questions

What is the difference between BMR and TDEE?

BMR (Basal Metabolic Rate) is the calories your body burns at rest just to stay alive. TDEE (Total Daily Energy Expenditure) includes your BMR plus calories burned through physical activity and exercise.

How many calories should I eat to lose weight?

A safe weight loss target is eating 300 to 500 calories below your TDEE daily, which leads to ~0.5kg (1lb) of steady fat loss per week.
