Objective: Eating until one is 80% full is considered a healthy dietary practice in Japan. This study examined the relationship between this behavior and energy intake and types and quantities of foods consumed to examine its beneficial effects.

Methods: This study relied on dietary records and self-administered questionnaires completed by 330 users of a health-management website in November 2012. ANOVA was performed to examine the relationship between eating until one is 80% full and intake.

Results: Men who always ate until they were 80% full consumed less energy than those who did not (mean [SD]; always: 1997.3 [356.7] kcal; rarely/never: 2448.9 [637.1] kcal; p<0.05). Moreover, men who ate until they were 80% full consumed fewer servings of grain dishes (always: 3.7 [0.9] servings; rarely/never: 5.1 [1.9] servings; p<0.05) and more servings of vegetable dishes (always: 5.9 [2.2] servings; rarely/never: 4.0 [2.3] servings, p<0.05) than those who did not.

Conclusion: Men who ate until they were 80% full consumed less energy and more vegetable dishes than those who did not, suggesting that eating until one is 80% full is associated with healthy dietary habits among men.
