I investigated nutritional intake condition in the present time for a male university student belonging to the regulation baseball team for the intervention to lose weight in near future. I used the photographic dietary assessment for the investigation and the subject was instructed to take pictures of his diets (all diets without water) in separated three days includes both week day and holiday. For the estimation of caloric intake, we used exclusive software. At the same time, I asked some questions including his height and position, and measured body weight and body fat ratio (height: 170.2 cm, body weight: 87.6kg, body fat ratio: 27.3%). As a result of nutritional investigation, I observed the lower intake of energy, carbohydrate, dietary fiber, vitamin A, vitamin B1, vitamin B2, and vitamin C, and the higher intake of protein. The reason why participant did not lose weight in spite of the lower intake of energy may be the effect of the chronically energy shortage and the higher intake protein. Therefore, I planned to reduce the protein intake with keeping the energy intake.
