Cutting
A cut is a deficit phase to lose fat while protecting muscle. Strength + protein + a moderate deficit beat extreme diets.
Definition
A cutting phase (or "cut") is a period where you intentionally eat in a caloric deficit to lose body fat, while training hard to preserve muscle mass built during a previous bulk or maintenance phase.
💡 The goal of a cut is NOT to lose weight — it's to lose fat while keeping muscle. Two very different things.
The 3 types of cutting
| Type | Deficit | Result |
|---|---|---|
| Mini cut | -500 to -700 kcal/day | Fast: 0.7-1 kg/week, 4-6 weeks max |
| Standard cut (recommended) | -300 to -500 kcal/day | Balanced: 0.4-0.6 kg/week, 8-16 weeks |
| Slow cut | -150 to -300 kcal/day | Sustainable: 0.2-0.4 kg/week, 12-20+ weeks |
⚠️ A deficit greater than -700 kcal/day causes significant muscle loss, hormonal disruption, and a strong rebound risk.
The 4 nutritional pillars of cutting
- ✅ Caloric deficit: -300 to -500 kcal below your TDEE
- ✅ High protein intake: 2-2.5 g/kg of bodyweight (vs 1.6-2 g/kg in maintenance)
- ✅ Sufficient fats: 0.8-1 g/kg minimum (hormone health)
- ✅ Carbs adapted to training: more on training days, less on rest days
How to preserve muscle during a cut
Losing fat without losing muscle is the real challenge. Strategies that work:
- ✅ Keep training heavy: maintain your usual loads, the signal to keep muscle
- ✅ Reduce volume slightly: -10 to -20% if recovery suffers
- ✅ Don't kill yourself with cardio: 2-3 sessions/week max if needed
- ✅ Quality sleep: 7-9h, non-negotiable
- ✅ Manage stress: chronic cortisol = muscle catabolism
- ✅ Refeed days: 1-2 days/week at maintenance to restore glycogen
How long should a cut last?
| Starting body fat | Recommended duration |
|---|---|
| 10-12% (men) / 18-20% (women) | 4-6 weeks (mini cut) |
| 15-18% (men) / 22-25% (women) | 8-12 weeks (standard cut) |
| 20%+ (men) / 28%+ (women) | 12-20+ weeks, with diet breaks |
A cut longer than 16 weeks without diet breaks risks strong metabolic adaptation. Plan strategic 1-2 week breaks at maintenance.
Common mistakes
- ❌ Excessive deficit ("the harder I cut, the faster I lose")
- ❌ Cutting protein along with calories
- ❌ Doing cardio every day instead of fixing the diet
- ❌ Cutting fats below 0.5 g/kg (hormonal collapse)
- ❌ Stopping training when energy drops (muscle loss accelerates)
- ❌ Weighing yourself daily and stressing on water fluctuations
Key takeaways
A successful cut is moderate, structured, patient. -400 kcal/day, 2 g of protein/kg, heavy training maintained. 0.5-1% bodyweight lost per week is the sweet spot. Below that = too slow. Above = muscle loss. Slow and steady wins the race.
Common questions
What is a cutting phase?
A calorie-deficit phase aimed at losing fat while preserving muscle, with strength training and high protein.
Ideal rate of loss?
Often ~0.25–0.75% of body weight per week. Faster rates raise muscle loss and fatigue risk.
Should you stop lifting while cutting?
No. Strength training and solid protein intake are central to keeping lean mass.
