Timeline by Deficit Level
How long it takes to go from 25% to 10% body fat at each deficit level. The recommended deficit is highlighted.
| Deficit | Difficulty | Weeks | Daily Calories | Weekly Loss |
|---|---|---|---|---|
| 15% Gentle | Easy | ~34 | 2,230 | 0.79 lbs |
| 20% ModerateRecommended | Easy | ~26 | 2,099 | 1.05 lbs |
| 25% Effective | Moderate | ~21 | 1,968 | 1.31 lbs |
| 30% Fast | Hard | ~17 | 1,837 | 1.57 lbs |
| 35% Intense | Very Hard | ~15 | 1,706 | 1.84 lbs |
| 40% Extreme | Extreme | ~13 | 1,574 | 2.1 lbs |
Best Approach
A 15 percentage point drop is a significant transformation that requires a phased approach. Start at 20% deficit for 8 weeks, take a 1-2 week diet break at maintenance, then resume at 25% deficit for another 6-8 weeks. Expect this to take 4-5 months including diet breaks. Do not try to rush it with an aggressive deficit. The risk of muscle loss and burnout is too high over this duration.

Muscle Retention Strategy
Protein at 1g per lb lean mass. Creatine monohydrate (5g daily) helps preserve strength. Maintain compound lift intensity but reduce total volume by 15-20% compared to maintenance. Do not introduce new exercises. Stick with movements your body knows. Track your key lifts weekly. If strength drops more than 10%, your deficit is too aggressive or you need a diet break.
Phased Approach
This is a major body composition change that requires multiple phases. Phase 1: 20% deficit for 10-12 weeks. Maintenance break: 4-6 weeks. Phase 2: 20-25% deficit for 8-10 weeks. Maintenance break: 4 weeks. Phase 3 (if needed): 25% deficit for 6-8 weeks. Total timeline: 6-10 months including maintenance breaks. Trying to rush this with an aggressive deficit leads to muscle loss, metabolic slowdown, and diet fatigue. The phased approach produces a better end result.
Plateau Warning
Long cuts have multiple plateaus. The first typically hits around weeks 6-8, the second around weeks 14-18. Each plateau lasts 1-3 weeks. Use diet breaks (1-2 weeks at maintenance) to break through plateaus instead of cutting calories further. Your TDEE drops as you lose weight, so recalculate your calorie target every 4-6 weeks.
Frequently Asked Questions
What will I look like at 10% body fat?
Check the FitCommit Body Fat Guide for a detailed visual reference and body composition breakdown at 10% body fat.
How many calories should I eat to go from 25% to 10%?
At the recommended 20% deficit, a 5'10", 180 lb man would eat approximately 2099 calories per day. Your exact number depends on your weight, height, and activity level. Use FitCommit to calculate your personal target.
Do I need to take diet breaks during this cut?
Absolutely. Plan for multiple diet breaks (1-2 weeks at maintenance) between cutting phases. Without breaks, your metabolism adapts and progress stalls. The breaks are part of the plan, not a failure.
Can I build muscle while going from 25% to 10%?
If you are new to training, yes. Beginners at higher body fat percentages can build muscle in a calorie deficit (body recomposition). This effect diminishes as you get leaner and more experienced.
