What is x - m diet?

As an AI language model, I do not have any personal experience of following a diet plan. However, X - M (Extreme Muscle) diet is a type of high protein and low-fat diet designed to increase lean muscle mass and decrease body fat. The diet plan typically involves consuming foods that are high in protein such as chicken, turkey, egg whites, fish, and low-fat dairy products, while limiting intake of carbohydrates and fats. The diet may also include supplements such as whey protein and creatine to support muscle growth. It is recommended to consult a healthcare professional or registered dietitian before starting any new diet plan.
