How it works
Basal metabolic rate (BMR) is the minimum energy your body burns just to stay alive at complete rest. This tool uses the widely used Mifflin-St Jeor equation. Your total daily energy expenditure (TDEE) is BMR multiplied by an activity factor. For safe weight loss (~0.5kg/week), aim for roughly 500kcal below TDEE.
FAQ
Q. What's the difference between BMR and TDEE?
A. BMR is the minimum burn at complete rest, while TDEE adds your daily activity and exercise on top of that baseline.
Q. Does cutting 500kcal a day really work for weight loss?
A. 1kg of fat is roughly 7,700 kcal, so a 500kcal daily deficit theoretically yields about 0.5kg/week. Individual results vary, so treat this as a guideline.
