食事と運動について Do you know your adequate energy requirenebt and energy expenditure?
Obesity is the principal risk factor of type 2 diabetes, and is developed when the energy intake exceeds the energy expenditure. Dietary and exercise intervention has been thought to play as important role in the treatment and prevention of type 2 diabetes. In this review, the balance of energy intake and energy expenditure is introduced. The amount of energy requirement was obtained by the calculation with ideal body weight and physical activity（low level : 25～30 kcal/kg, normal level : 30～35 kcal/kg）. Furthermore, both quantity and quality of the food are important. It has been reported that low-glycemic index diet is effective in the prevention and the treatment of type 2 diabetic patients. Exercise can also improve insulin sensitivity in muscle and liver. Recently, reference values for the quantity of physical activity（23MET・hours/week）and exercise （4MET・hours/week）for health promotion was established as the recommended exercise allowance for preventing lifestyle-related disease. It is important for us to understand an adequate and correct amount of individual energy requirement and expenditure.
