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.

Frequently Asked Questions
What will I look like at 20% body fat?
Check the FitCommit Body Fat Guide for a detailed visual reference and body composition breakdown at 20% body fat.
How many calories should I eat to go from 25% to 20%?
At the recommended 25% deficit, a 5'10", 180 lb man would eat approximately 1968 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?
For a short cut like this, diet breaks are optional. You should be able to complete the phase in one block without metabolic issues.
Can I build muscle while going from 25% to 20%?
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.
