OBJECTIVE: The objective was to compare the effects of 3 ad libitum diets on the maintenance of an initial weight loss of >or=8{\%} and risk factors for CVD and diabetes during a 6-mo controlled dietary intervention. DESIGN: Nondiabetic overweight or obese [mean +/- SD body mass index (in kg/m(2)): 31.5 +/- 2.6] men (n = 55) and women (n = 76) aged 28.2 +/- 4.8 y were randomly assigned to a diet providing a moderate amount of fat (35-45{\%} of energy) and >20{\%} of fat as monounsaturated fatty acids (MUFA diet; n = 54), to a low-fat (20-30{\%} of energy) diet (LF diet; n = 51), or to a control diet (35{\%} of energy as fat; n = 26). Protein constituted 10-20{\%} of energy in all 3 diets. All foods were provided free of charge from a purpose-built supermarket. RESULTS: More subjects dropped out of the MUFA (28{\%}) group than out of the LF group (16{\%}) and control group (8{\%}) (MUFA compared with control: P <0.05). All groups regained weight (MUFA: 2.5 +/- 0.7 kg; LF: 2.2 +/- 0.7 kg; and control: 3.8 +/- 0.8 kg; NS). Body fat regain was lower in the LF (0.6 +/- 0.6{\%}) and MUFA (1.6 +/- 0.6{\%}) groups than in the control group (2.6 +/- 0.5{\%}) (P <0.05). In the MUFA group, fasting insulin decreased by 2.6 +/- 3.5 pmol/L, the homeostasis model assessment of insulin resistance by 0.17 +/- 0.13, and the ratio of LDL to HDL by 0.33 +/- 0.13; in the LF group, these variables increased by 4.3 +/- 3.0 pmol/L (P <0.08) and 0.17 +/- 0.10 (P <0.05) and decreased by 0.02 +/- 0.09 (P = 0.005), respectively; and in the control group, increased by 14.0 +/- 4.3 pmol/L (P <0.001), 0.57 +/- 0.17 (P <0.001), and 0.05 +/- 0.14 (P = 0.036), respectively. Dietary adherence was high on the basis of fatty acid changes in adipose tissue. CONCLUSIONS: Diet composition had no major effect on preventing weight regain. However, both the LF and MUFA diets produced less body fat regain than did the control diet, and the dropout rate was lowest in the LF diet group, whereas fasting insulin decreased and the homeostasis model assessment of insulin resistance and ratio of LDL to HDL improved with the MUFA diet.
