Many bodybuilders follow the guidelines for low-carb diets, or diets high in protein, simply because protein is considered the building block of muscle. Plus, there is a general perception that too many carbohydrates can cause weight gain
Bodybuilders on a low-carb diets do not eliminate carbs completely. Instead complement the meals with “good” carbohydrates, such as non-starchy vegetables (spinach, green beans and broccoli).
Low-carb dieting does not always mean less calories a bodybuilder. It just means getting most of your calories from protein-packed food. These include chicken, lean meats and fish of all kinds.
Chances are bodybuilders on low-carb diets do not get all the protein they want (usually 1 gram per kilogram of body weight) through meals alone. Many people use protein-enriched supplements like protein shakes, protein bars or protein pills.
Bodybuilders follow a diet consisting of weightlifting and cardio exercises, and that combined with a low-carb diet can sometimes leave them with feelings of hunger and lack of energy.
