Timeline by Deficit Level
How long it takes to go from 15% to 10% body fat at each deficit level. The recommended deficit is highlighted.
| Deficit | Difficulty | Weeks | Daily Calories | Weekly Loss |
|---|---|---|---|---|
| 15% Gentle | Easy | ~10 | 2,462 | 0.87 lbs |
| 20% Moderate | Easy | ~8 | 2,318 | 1.16 lbs |

| 40% Extreme | Extreme | ~4 | 1,738 | 2.32 lbs |
Best Approach
A 5 percentage point drop is a short cut. For most men, a 20-25% deficit (Moderate to Effective) for 6-10 weeks handles this comfortably. Start with the Moderate 20% deficit if this is your first cut. Move to 25% if you are experienced and want to finish faster.
