The Science of Fat Loss
Energy Balance
Fat loss occurs when your body uses more energy than it consumes. This creates a calorie deficit that forces your body to use stored fat for energy.
- 7,700 calories equals approximately 1 kg of fat
- Safe fat loss rate is 0.5-1 kg per week
- Sustainable deficit ranges from 500-1000 calories daily
Metabolic Processes
Your metabolism determines how efficiently your body burns calories. Understanding these processes helps optimize your fat loss journey.
- BMR accounts for 60-70% of daily calorie burn
- Physical activity adds 15-30% to calorie expenditure
- Thermic effect of food contributes 10%
