How long to lose 25 pounds?
One pound of fat is roughly 3,500 calories, so losing 25 lb takes about a 87,500-calorie total deficit. Here's how long it takes at different daily deficits:
| Daily deficit | Time | ≈ |
|---|---|---|
| 250 cal/day deficit | 50.0 weeks | 11.7 months |
| 500 cal/day deficit | 25.0 weeks | 5.8 months |
| 750 cal/day deficit | 16.7 weeks | 3.9 months |
| 1000 cal/day deficit | 12.5 weeks | 2.9 months |
A deficit of 500 calories/day (about 25 weeks for 25 lb) is a common, sustainable target. Avoid very aggressive deficits.
