Peter Neilsen, a former Mr. USA, began working as a fitness and nutritional consultant in 1981. He has trained such famous personalities as Joe Montana, Isiah Thomas, Donna Summer, and Billy Joel.
At age 15, Peter was diagnosed with Crohn's Disease. He lost 59 pounds, most of his hair, and spent two months undergoing tests in a Brooklyn, New York hospital. He had surgery, where doctors removed over two feet of his intestines and gave him a temporary ostomy. Today he has been in remission for over 15 years, and no longer takes any medication.
