Health claim
“Simultaneous fat loss and muscle gain (body recomposition) is achievable through optimized nutrition and training strategies.”
Claim checked — mixed / earlyLow risknutrition
Evidence Summary
Some evidence supports this, but findings are inconsistent or limited in scope.
Research shows that simultaneous fat loss and muscle gain can occur under specific conditions (e.g., novice trainees, caloric deficit with high protein, resistance training), but the magnitude is limited and not typical for experienced athletes.
