Fitness and muscle exercise are hot topics for adults. Fitness is to strengthen the body, and the purpose of muscle building is to increase muscle mass by improving diet and exercise. Daily diet infusion during muscle building is very important for keeping fit and finally achieving the goal of muscle building, and carbohydrate is one of the important nutrients for muscle building.

Carbohydrate is an essential nutrient in diet, which can be used as an energy source to support the body to carry out various exercises. In the process of fitness and muscle building, carbohydrate intake is necessary, because it can help muscle cells grow without protein. In addition, a reasonable carbohydrate diet can maintain normal blood sugar level, promote metabolism, and make the body better absorb other important nutrients.

However, the proportion of carbohydrates should be kept moderate relative to the protein intake required for muscle gain. Especially for sensitive people, eating too much carbohydrates may lead to weight gain and other health problems. Therefore, it is suggested that we mainly consume complex carbohydrates from whole grains, fruits and vegetables in our diet, and avoid excessive intake of monosaccharide or disaccharide carbohydrates that increase empty calories. Whether it is a fitness enthusiast or a beginner with sports experience, reasonable nutrition intake is very important.
