Do you need carbs to build muscle?
Carbohydrate intake and resistance-based exercise: are current recommendations reflective of actual need?

You don’t need lots of carbs to get stronger or grow muscle — protein is what really matters.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Increased carbohydrate intake enhances intramuscular glycogen storage, thereby improving resistance training performance and volume capacity.
Rats that ate almost no carbs but lots of fat and protein still grew just as much muscle as rats eating a normal high-carb diet when both did weightlifting.
If you eat enough protein (like 25g per meal), your muscles will grow even if you eat almost no carbs—carbs aren’t needed for building muscle.
Even eating very little carbs—like just 30 grams a day—doesn’t make you weaker during weightlifting workouts, which means you might not need to eat a lot of carbs to lift heavy.
Even if your muscles are low on stored sugar (glycogen), your body still builds muscle just as well after lifting weights, as long as you eat enough protein.
