Weight Loss per Week vs Daily Caloric Deficit
公式
## 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.
计算示例
A 500 calorie daily deficit over 12 weeks.
- 01Weekly deficit = 500 x 7 = 3,500 cal
- 02Loss per week = 3,500 / 3,500 = 1.0 lb/week
- 03Total loss = 1.0 x 12 = 12.0 lbs
- 04In kg = 12.0 x 0.454 = 5.4 kg
常见问题
How much weight can I lose per week safely?
Most health experts recommend 1-2 lbs per week (a deficit of 500-1000 cal/day). Faster loss may lead to muscle loss and nutrient deficiencies.
Is 3,500 calories really 1 pound?
The 3,500 cal/lb rule is an approximation. Actual results vary because your metabolism adapts over time and weight loss is not purely fat.
