Ian is an 18-year-old gymnast training in a private gym with many other male and female gymnasts. He is competing at an advanced level and is likely to make the next Olympic team. Lately he has been finding some of his balance and strength moves on the rings and parallel bars more difficult. He has gone through a bit of a growth spurt and has gained approximately 5 pounds over the last year. He suspects the weight gain is causing his performance difficulties. He decides to try a weight loss program that will help you lose weight before his next big competition in six weeks. He is not sure how many calories to consume and therefore arbitrarily decided to eat 1,500 kcal per day.
