Assessment of weight loss options can help consumers and practitioners determine the best way to manage weight. This quasi-experimental study evaluated outcomes for participants (n = 1592; body mass index: 35.7±7.5 kg/m2) enrolled in the LIFESTEPS Weight Management Program. Body adiposity, self-efficacy, and lifestyle behaviors were assessed at program entry and exit. Body weight, body mass index, waist circumference, and waist-to-height ratio decreased and self-efficacy increased. More participants reported keeping food records, consuming fruits and vegetables, and participating in physical activity at program exit. Programs that emphasize nutrition, physical activity, and behavior therapy, such as LIFESTEPS, are appropriate options for weight loss.
