Understanding Your Results

• Weekly Loss Rate: How much weight you'll lose each week to reach your goal in the specified timeframe

Important Health Guidelines

Safe and sustainable weight loss is typically 0.5-1 kg per week. Losing weight too quickly can lead to muscle loss, nutritional deficiencies, and other health issues. This calculator will warn you if your target timeframe is too aggressive.

Note: One kilogram of body fat equals approximately 7,700 calories. This calculator uses this standard conversion to estimate your required calorie deficit.
