NCT00826774

Brief Summary

The purpose of the study is to compare three methods of achieving weight loss in primary care medical practice. The study will be conducted in six primary care practices. Weight management will be provided to a total of 390 obese patients (who have 2 or more components of the metabolic syndrome) by their own primary care providers, in conjunction with the practices' auxiliary health professionals, including medical assistants.

Interventions

Usual CareBEHAVIORAL

Participants in this group will receive usual medical care, provided by their own primary care providers (PCPs). PCPs also will provide participants recommendations for weight management at quarterly-scheduled visits.

Ususal Care

These participants, like those in the Usual Care group, will receive the same PCP visits, plus monthly brief counseling sessions with an auxiliary health care provider (e.g., a medical assistant), on-site or by phone.

Breif Lifestyle Counseling

These participants will receive the same intervention as those in the Brief Lifestyle Counseling condition, including quarterly PCP visits and monthly sessions with a medical assistant who will instruct them in lifestyle modification. These individuals also will select, in consultation with their PCP, the use of either meal replacements or weight loss medication, to facilitate the induction and maintenance of weight loss
