How long to lose 10 pounds?
One pound of fat is roughly 3,500 calories, so losing 10 lb takes about a 35,000-calorie total deficit. Here's how long it takes at different daily deficits:
| Daily deficit | Time | ≈ |
|---|---|---|
| 250 cal/day deficit | 20.0 weeks | 4.7 months |
| 500 cal/day deficit | 10.0 weeks | 2.3 months |
| 750 cal/day deficit | 6.7 weeks | 1.6 months |
| 1000 cal/day deficit | 5.0 weeks | 1.2 months |
A deficit of 500 calories/day (about 10 weeks for 10 lb) is a common, sustainable target. Avoid very aggressive deficits.
