Meal patterns in obese and normal weight men: the 'Gustaf' study.
OBJECTIVE
To compare the reported meal patterns between obese and normal weight men.


METHODS
A dietary survey, by means of 12 repeated telephone-administered 24-hour dietary recalls, was conducted in obese and normal weight men. The study period was three months with all seven days of the week included. The contribution of intake types to the reported daily energy intake (EI) was studied as well as the circadian distribution of EI and the reported number of intakes.


METHODS
86 obese men (BMI 37.7 +/- 4.4 kg/m2, mean +/- SD) from the waiting list of the outpatient clinic completed the study altogether with 61 normal weight men (BMI 23.0 +/- 1.9 kg/m2), randomly selected from the Stockholm County Census Bureau. All men were 20-60 years old.


RESULTS
Results were analyzed for Group A = all men who completed the study and for Group B = the men who exceeded the CUT-OFF 1 limit for energy intake (reasonably true report as defined by Goldberg). The obvious under-reporters amounted to 73% of the obese and to 28% of the normal weight men. The meal patterns were similar for the obese and the normal weight men. The greatest contributors to EI in both groups were cooked meals, sandwich meals, snacks and breakfast-like meals. The circadian eating pattern was mainly the same in both obese and normal weight men. The reported number of intakes was 5.3 (median) per day in all obese men vs 5.6 in all the controls (P = 0.02), and in Group B 5.3 s 5.9 (P = 0.16) intakes. No specific "obese eating style' could be detected in this study.
