Macro partitioning
Long-term carbohydrate manipulation (weeks to months) does not influence strength gains or hypertrophy in strength-trained individuals, provided total caloric and protein intake are adequate.
You do not need to eat a high-carbohydrate diet to build muscle or get strong. Focus on hitting your protein targets and maintaining a caloric surplus (if bulking) or deficit (if cutting). You can choose your carbohydrate intake based on preference, activity level, or metabolic health without sacrificing strength gains.
GoodRefutesHIGH confidence
Longer-term changes in performance were not influenced by carbohydrate intake in 15 studies; one study favored the higher- and one the lower-carbohydrate condition.
Why this rating
Systematic review of 17 long-term studies, mostly showing no difference.
