Frequently asked questions
- Is 1 lb of fat really 3,500 calories?
- The 3,500 kcal/lb figure is an approximation. The more precise value is ~7,700 kcal/kg which equals ~3,500 kcal/lb (since 7700 ÷ 2.205 ≈ 3,493). In practice, actual loss is slower because the body adapts metabolically.
- Why doesn't my weight loss match this calculation?
- Real weight change also includes water retention, glycogen changes, and metabolic adaptation. The calculation gives a theoretical estimate, not a guarantee.
