Adherence

Self-reported behaviors of eating until full and eating quickly are independently and jointly associated with being overweight (BMI ≥25.0) in Japanese adults, with the combination of both behaviors producing a supra-additive increase in risk.

To manage weight, pay attention to how you eat, not just how much. Eating quickly and eating until full are linked to higher body weight, even when total calories are similar. Try to slow down your eating pace and stop when you are comfortably satisfied rather than completely full, as this may help regulate energy intake and weight status.

ModerateSupportsMEDIUM confidence
The multivariable adjusted odds ratio of being overweight for eating until full was 2.00 (95% confidence interval 1.53 to 2.62) for men and 1.92 (1.53 to 2.40) for women and for eating quickly was 1.84 (1.42 to 2.38) for men and 2.09 (1.69 to 2.59) for women. The multivariable odds ratio of being overweight with both eating behaviours compared with neither was 3.13 (2.20 to 4.45) for men and 3.21 (2.41 to 4.29) for women.

Why this rating

Cross-sectional design limits causal inference, but the large sample size (n=3287) and multivariable adjustments strengthen the association findings.
