Body Recomposition – Lose Fat, Gain Muscle
Plan a body recomposition: a small 200–300 kcal deficit with protein at 2.0–2.2 g/kg and heavy training to lose fat and build muscle at the same time.
Figures are estimates from this calculator’s standard formula — adjust the inputs in the tool below for your exact number.
How Recomposition Planning Works
Body recomposition — losing fat while gaining muscle — works when three signals align: a small calorie deficit just large enough to mobilize fat (200–300 kcal below maintenance), protein high enough to build (2.0–2.2 g/kg daily), and progressive resistance training 3–4 times a week. Beginners, returning lifters and overweight trainees recomp best, gaining 0.5–1 kg muscle per month while losing fat; lean advanced lifters recomp slowly or better use alternating cut/bulk phases. Worked example: an 85 kg man with a 2,700 kcal TDEE eats 2,450 kcal with 170 g protein, keeping fats at 0.8 g/kg and filling the rest with carbs around training. Expect the scale to move little while the tape measure and photos show the real change — judge recomp by waist and lifts, not weight.
- 1
Enter stats and training age
Your TDEE and recomp potential depend on training history
- 2
Set the small deficit
200–300 kcal under maintenance keeps training quality
- 3
Follow protein and lifting
2.0–2.2 g/kg protein and 3–4 heavy sessions per week
Use Cases
Beginner transformations
First-year lifters gain 0.5–1 kg muscle monthly in a deficit
Comeback after a break
Muscle memory makes regained tissue fast while fat falls
Athletic off-season
Hold weight class while improving strength-to-weight
Tips
- 1
Track waist and progress photos weekly, scale monthly
- 2
Recomp slower than bulk/cut — give it 12–16 weeks
- 3
Sleep 7–9 hours; poor sleep blunts recomposition sharply
Common Mistakes
Cutting 700+ kcal and losing muscle with the fat
Setting protein at 1.2 g/kg and hoping training saves it
Judging success by scale weight in month one
Adding endless cardio instead of heavy progressive lifting
