Cutting

A cutting phase is a period of caloric deficit aimed at losing fat while preserving muscle. Discover how to do it without losing your hard-earned gains.

Cutting - Lose fat without losing muscle

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

TypeDeficitResult
Mini cut-500 to -700 kcal/dayFast: 0.7-1 kg/week, 4-6 weeks max
Standard cut (recommended)-300 to -500 kcal/dayBalanced: 0.4-0.6 kg/week, 8-16 weeks
Slow cut-150 to -300 kcal/daySustainable: 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 fatRecommended 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.
