Cutting for bodybuilding requires a more aggressive and precise approach than general fat loss. While regular fat loss focuses on health and sustainability, cutting prioritizes maximum fat loss while preserving muscle definition. This means higher protein intake, strategic carb timing, and careful monitoring of training performance.
Successful cuts use a high-protein approach (40-45% of calories) to preserve muscle mass in a caloric deficit. Carbs are kept moderate (25-35%) and timed around workouts for performance, while fats are reduced to the minimum needed for hormone production (20-25%). This aggressive approach requires careful monitoring and adjustment.
Most cuts last 12-20 weeks depending on starting body fat and goals. Start conservatively with a 300-500 calorie deficit and adjust based on progress. Expect to lose 1-2 lbs per week initially, slowing to 0.5-1 lb per week as you get leaner. The last 4-6 weeks often require more aggressive deficits.
Mike is a 28-year-old bodybuilder preparing for a competition. He's 12 weeks out and needs to drop from 15% to 6% body fat while maintaining muscle mass.
With a TDEE of 2,700 calories, Mike's cutting plan creates a 500-calorie deficit. His high protein target (220g) ensures muscle preservation during the aggressive cut, while carbs are timed around workouts for performance. As he gets leaner, he may need to reduce calories further.
Common questions about macro calculation and nutrition planning.
When cutting, aim for 1.2-1.6 grams of protein per pound of body weight. This higher intake helps preserve muscle mass in a caloric deficit and provides greater satiety. Competitive bodybuilders often go even higher (1.4-1.8g/lb) during contest prep.
Cardio can help create a larger caloric deficit and improve conditioning, but it's not mandatory. Start with 2-3 cardio sessions per week and increase gradually. Prioritize weight training to preserve muscle mass—cardio is just a tool to increase calorie burn.
Don't go too low too fast. Start with 0.8-1.2g carbs per pound of body weight and reduce gradually as needed. Very low carbs can hurt training performance and muscle preservation. Save extreme low-carb approaches for the final weeks of a cut.
Contest prep is an extreme form of cutting that aims for stage-ready conditioning (3-6% body fat for men, 10-14% for women). It requires more aggressive deficits, precise timing, and often includes peak week strategies. Regular cutting stops at a healthier body fat level.
Monitor your strength in the gym, take progress photos, and track body measurements. Some strength loss is normal in a deficit, but dramatic drops may indicate muscle loss. Ensure adequate protein, don't cut calories too aggressively, and prioritize sleep and recovery.
