Key Facts: Macro Calculator for Body Recomposition

  • Recomp is most efficient at 0–10% below maintenance
  • Protein: 2.0–2.4 g/kg — the highest-evidence lever
  • Progressive overload in the gym is non-negotiable
  • Expect slow visible change — measure quarterly, not weekly

Special Considerations for Body recomposition

  • Recomp is slow: plan in 6-month blocks, not 6-week
  • Sleep 7–9 h — recovery drives both muscle gain AND fat loss
  • Don't chase daily scale changes; track photos + measurements
  • Advanced lifters often recomp only during short deload phases
