Randomized Controlled Trial

Some concerns

Age 18-55 years old; BMI 27-43; willingness to be randomly assigned to 1 of 2 treatment-preference conditions and 1 of 2 dietary conditions; successful completion of a 5-day food dairy; willingness and ability to provide informed consent.

Current medical condition requiring physician supervision of diet or physical activity (for example diabetes, post-acute myocardial infarction); physical limitation restricting exercise ability; pregnancy or intention to become pregnant during the 18-month study; current treatment with a medication that might affect weight; alcohol intake >4 drinks/day participation in a weight-loss program or use of a weight-loss medication within the past 6 mo; abstention from eating meat, poultry or fish in the past month;

We designed the present study to test two hypotheses: (1) choice of either a standard calorie- and fat-restricted diet (STD-D) or a calorie- and fat-restricted LOV-D would result in greater weight loss compared to having one of these diets randomly assigned; and (2) an LOV-D would result in greater weight loss than a STD-D.
