Objective To examine whether eating until full or eating quicklyor combinations of these eating behaviours are associated withbeing overweight.

Design and participants Cross sectional survey.

Setting Two communities in Japan.

Participants 3287 adults (1122 men, 2165 women) aged 30-69 whoparticipated in surveys on cardiovascular risk from 2003 to2006.

Main outcome measures Body mass index (overweight $≥$ 25.0) andthe dietary habits of eating until full (lifestyle questionnaire)and speed of eating (validated brief self administered questionnaire).

Results 571 (50.9%) men and 1265 (58.4%) women self reportedeating until full, and 523 (45.6%) men and 785 (36.3%) womenself reported eating quickly. For both sexes the highest ageadjusted mean values for height, weight, body mass index, andtotal energy intake were in the eating until full and eatingquickly group compared with the not eating until full and noteating quickly group. The multivariable adjusted odds ratioof being overweight for eating until full was 2.00 (95% confidenceinterval 1.53 to 2.62) for men and 1.92 (1.53 to 2.40) for womenand 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 beingoverweight with both eating behaviours compared with neitherwas 3.13 (2.20 to 4.45) for men and 3.21 (2.41 to 4.29) forwomen.

Conclusion Eating until full and eating quickly are associatedwith being overweight in Japanese men and women, and these eatingbehaviours combined may have a substantial impact on being overweight.
