## Weight Loss Calculation

**Pounds per week = (Daily Deficit x 7) / 3,500**

Approximately 3,500 calories equals one pound of body fat.

### Safe Weight Loss Rates

| Deficit | Loss/Week |
|---|---|
| 250 cal/day | 0.5 lbs |
| 500 cal/day | 1.0 lbs |
| 750 cal/day | 1.5 lbs |
| 1000 cal/day | 2.0 lbs |

A deficit of 500-1000 cal/day is generally considered safe.

Exemple Résolu

A 500 calorie daily deficit over 12 weeks.

  1. Weekly deficit = 500 x 7 = 3,500 cal
  2. Loss per week = 3,500 / 3,500 = 1.0 lb/week
  3. Total loss = 1.0 x 12 = 12.0 lbs
  4. In kg = 12.0 x 0.454 = 5.4 kg
