Ju, Shin, and Kim: A study on body awareness and dietary life of adults who perform regular exercise

Abstract

This study was conducted in order to investigate body awareness and dietary life according to gender. Subjects of the study were 120 men and 127 women aged 20 to 30 years, who exercise regularly at a fitness center in Seoul. The subjects were asked to fill out a questionnaire on body awareness, reason for regular exercise, dietary behaviors, and nutrition knowledge. The percentage of overweight and obesity was 69.2% in men, and 25.2% in women. The percentage of subjects who considered themselves as overweight was 38.3% in men and 59.8% in women. Intake of protein in men was higher than the recommended nutrient intake (RNI). Intake of energy in women was lower than the estimated energy requirement (EER). Men who considered themselves as overweight showed lower energy intake than men who considered their body weight as under and normal, whereas no difference in energy intake was observed between women who considered themselves as overweight and women who considered their body weight as under and normal.
