When you eat very few carbs, your body breaks down important muscle-building amino acids instead of using them to grow muscle, making it harder to get stronger from weight training.

Eating more carbs doesn’t make your muscles grow bigger when you’re already getting enough protein and calories — your muscles respond more to lifting weights than to how many carbs you eat.

When you eat very few carbs, your body burns up the protein you eat for energy instead of using it to repair and build muscle.

When doing strength training, consuming more protein leads to greater muscle growth than consuming the same amount of calories from carbohydrates or fats.
