Meal pattern and risk factor evaluation in one-year completers of a weight reduction program for obese men - the 'Gustaf' study.
OBJECTIVE
To evaluate changes in meal patterns and in obesity related risk factors after 1 year of treatment in obese men.


METHODS
Data from two 24-h dietary recalls, performed at base-line and after 1 year of treatment, were related to changes in medical risk factors.


METHODS
Academic obesity unit.


METHODS
Sixty-three men, aged 44 (eight) years (mean [SD]) and Base-line Body Mass Index (BMI) 37.4 (4.6) kg m-2, who had completed 1 year of treatment. The men were subdivided by tertiles according to weight change: tertile I (n = 21), mean +0.3 kg, tertile II (n = 21), mean -5.8 kg and tertile III (n = 21), mean -14.2 kg.


METHODS
Weight loss, changes in meal patterns and in obesity related medical risk factors.


RESULTS
The reported mean energy intake decreased after treatment in tertiles II and III by 700 (1300) kcal (P < 0.05) and 700 (900) kcal (P = 0.001), respectively. In tertile III the energy-% from fat decreased (P < 0.05) with a reciprocal increase in energy-% from protein (P < 0.05). The frequency of snacks of a low nutritional quality decreased (P < 0.01) in tertile III together with an increase in energy-% from 'hot meals of good quality' (P < 0.05). Obesity related risk factors (anthropometry, blood pressure, serum lipid concentrations, blood glucose and plasma insulin) improved in a beneficial way only in tertile III.


CONCLUSIONS
The weight loss in the successful tertile III men was to a great extent explained by fewer low quality snacks but more energy from high quality meals. These changes reflected the behaviour modification strategy recommended.
