The Insanity workout is a fitness program offering body transformation through various forms of interval training over a 60-day period. Each workout includes exercise components of upper body resistance, cardio and plyometrics. As National Institutes of Health’s MedlinePlus reports, proper nutrition that includes protein is important for overall health and athletic performance.
The Role of Protein
MedlinePlus advises that protein is crucial for muscle growth and the repair of body tissues. This includes muscle tissues affected by intense exercises, such as those in the Insanity workout. In addition to protein sources via food, protein shake supplements before and after workouts are also viable options. In fact, according to a 2008 study conducted by the Nutrition and Metabolism Journal, whey-protein supplements help to retain lean muscle and increase fat loss in obese patients. While there are a variety of sources for protein shakes, Beachbody, the maker of the Insanity workout program, sells high-protein meal replacement shakes that offer a blend of soy and whey protein ingredients.
However, as MedlinePlus points out, too much protein -- from any source -- is counterproductive, because excess protein is stored as body fat and will increase your chances of becoming dehydrated or losing calcium. Consult with your physician before starting Insanity or any exercise and nutrition program.
