ℹ️ About this tool
1 kg of body fat contains roughly 7,700 calories. This calculator determines your TDEE and the daily deficit needed to lose the desired weight in your timeframe. A deficit over 1,000 cal/day or eating below 1,200 cal/day (women) or 1,500 cal/day (men) is generally not recommended. All calculations happen in your browser.
