Carbohydrate-free meals may be healthy for some individuals. A low-carbohydrate, high-protein diet may promote weight loss and regulate blood sugar. Carbohydrates are the human body's main source of energy and dietary fiber; therefore, it is unhealthy to completely eliminate carbohydrates from the diet.
Every person requires a combination of fats, proteins and carbohydrates to survive. Carbohydrates are important for brain and muscle function, intestinal health and waste removal. Some people may choose to temporarily reduce their intake of carbohydrates to lose weight or improve their blood sugar levels. For these people, carbohydrate-free meals are healthy once in a while.
Carbohydrates are especially important for people who exercise regularly, as they provide the body with the energy it needs to move and function. A healthier choice is to include a small amount of high-quality carbohydrates -- such as whole grains or legumes -- at each meal.
