Problem: Harry is a 19-year-old college student who is very interested in bodybuilding. His dream is to compete in a local bodybuilding competition next summer. In August 2019 (beginning of the school year) he is 6'1" and weighs 178 lbs, with a percent body fat of 21%. He is beginning a work- out program, which consists of 1-2 hours every day of weights; working different body part each day. His goal is to gain 45 pounds of muscle and be 5% body fat. After listening at the gym, he has started taking several dietary supplements that include soy protein isolates, vitamin E, and creatine. The gym he attends has high-quality equipment and services. Among the gym's services are cardiovascular and respiratory evaluation, fat analysis, and nutrition counseling.

What Harry knows about nutrition comes from various bodybuilding magazines and the internet. He has put himself on a high-protein, low-carbohydrate, and no fat diet. Harry is eating 2 oz of broiled skinless boneless chicken breast at each meal, four raw eggs blended in a shake every evening and, 10 g of protein powder before and after every work out. The protein powder is a combination of 4 amino acids (leucine, isoleucine, valine and glutamine) to which he blends into water. He is also taking a high potency multiple vitamin and mineral tablet with breakfast every day. Somewhere he read that vitamin E prevents oxidative stress caused by physical activity, so he takes a Vitamin E supplement each day. He has also read that Vitamin C is necessary for protein synthesis, so he takes 4 g of it every day. (Both of these single vitamins supplements are in addition to the multiple vitamin & mineral supplement). He bought a "fat burner" supplement which he ordered off a late-night infomercial to help faster decrease is percent body fat. 

In March 2020, Harry decides to use the gym's service of bioelectrical impedance testing to measure his body fat. His progress: 25 pound weight gain and with a body fat of 19%. Initially he was very happy and excited but then depression set in since he was still far from his goal. He decides that he must lose weight faster and increases his workouts to 5-6 hours/day, cuts our all carbs and fat. After 4 weeks of his new regime, he notices that he gets light-headed and tired after about 10 minutes when doing his daily plyometric exercises.  He does not understand why, because he is able to do lift free weights for hours without any adverse effects. Harry decides to ask one of the trainers at the gym about this. You are that trainer, what do you say?
