Abstract
This survey identifies the body perception and lifestyle habits of high school students from the results obtained in a questionnaire survey of 1254 such students. High school boys had a body perception which was almost in agreement with BMI. In contrast, high school girls had a body perception which was fat rather than BMI; 90.9％ of normal girls desired to be thinner, and even 48.1％ of thin girls. A difference was found between the boys and girls in their diet method, the boys tending to diet by exercise, while the girls applied dietary restriction. Skipping meals, lack of sleep, lack of exercise, and stress resulted in poor health. Most high school students who ate three meals every day and did not feel stress were healthy.
