Certain intolerances to foods, such as whey, casein and milk protein, can impair your fitness goals. These ingredients are the protein source for most shakes, which many athletes and gym members rely on to meet their daily protein requirements. Unfortunately, what many people do not realize is that the main ingredients in these shakes may be causing many gastrointestinal issues; including bloating, water retention, constipation, and gas. Not only can sensitivity towards whey cause these uncomfortable symptoms, it may also interfere with fat loss. Whenever the intestinal lining becomes inflamed, which occurs when there is ANY sensitivity to ANY food, the body’s natural metabolic rate will be forced to slow down. As the metabolism slows down, the amount of fat the body retains increases. This ultimately hinders fat loss and may lead to undesirable results from any exercise routine. So, if time spent in the gym is being contradicted by the shake consumed afterward, you may want to reconsider that shake and seriously think about taking a food sensitivity test. Results may vary by individual, consult your doctor today and see if this is right for you!
