Andersson I, Lennernäs M, Rössner S (Huddinge University Hospital, Huddinge; and Swedish Dairy Association, Stockholm, Sweden). Meal pattern and risk factor evaluation in one‐year completers of a weight reduction program for obese men – the ‘Gustaf’ study. J Intern Med 2000; 247: 30–38. Objectives To evaluate changes in meal patterns and in obesity related risk factors after 1 year of treatment in obese men. Design 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. Setting Academic obesity unit. Subjects 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. Main outcome measures 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
