What is Body Recomposition?
Body recomposition is the simultaneous process of losing body fat and gaining muscle mass. Unlike a traditional bulk-then-cut approach, recomposition aims to improve your body composition without a significant change in total body weight. The result is a leaner, more muscular physique at roughly the same scale weight.
Recomposition is most effective for people who are newer to resistance training, returning after a break, or carrying excess body fat. More advanced trainees may find dedicated bulking and cutting phases more effective for maximising muscle or fat loss rate, but recomposition remains viable for most recreational athletes.
The Recomposition Formula
- BMR (Mifflin-St Jeor): 10 × weight (kg) + 6.25 × height (cm) − 5 × age ± 5/161
- TDEE = BMR × Activity Multiplier (1.2 to 1.9)
- Recomp Calories = TDEE × 0.95 (approximately 5% below maintenance)
- Protein = 2.3 g/kg bodyweight (high protein is essential for recomp)
- Fat = 28% of recomp calories, Carbs = remaining calories
Why High Protein is Non-Negotiable for Recomp
At maintenance or slight deficit calories, muscle protein synthesis is easily disrupted. High protein intake (2.2–2.4 g/kg) provides the amino acid pool required to build and maintain muscle tissue even in a mild caloric deficit. Research consistently shows that higher protein intake during recomposition leads to better muscle retention and greater fat loss compared to lower protein approaches.
- Protein has a high thermic effect (20–30% of calories are used in digestion), boosting metabolism slightly.
- High protein increases satiety, making it easier to maintain a slight caloric deficit without hunger.
- Protein timing: distribute intake across 3–5 meals of 30–40g protein each for optimal muscle protein synthesis.
- Leucine threshold: each meal should contain at least 2–3g of leucine to maximally stimulate muscle protein synthesis.
Frequently Asked Questions
How long does body recomposition take?
Results from recomposition are slower than dedicated bulk or cut phases because you are doing both simultaneously. Expect to see noticeable changes in body composition after 3–6 months of consistent training and nutrition adherence. Progress is best measured with body measurements and progress photos rather than scale weight alone.
Do I need to count calories for recomp?
Tracking food intake — at least for the first few months — dramatically increases success rates by ensuring you are hitting protein targets and staying near your calorie goal. Many people underestimate food intake significantly without tracking. Once you develop familiarity with portion sizes, you may be able to maintain results intuitively.
What activity level should I select?
Select the level that reflects your typical weekly physical activity including exercise, walking, and job activity. If you sit at a desk all day and exercise three times a week, choose 'lightly active'. If you have a physically demanding job and also train regularly, choose 'very active'. When in doubt, start with a slightly lower multiplier and adjust based on real-world weight trends.
