Inclusion Criteria:

  1. Women and men
  2. Ages 18 to 70 years
  3. Body mass index > 25 kg/m2 but < 55 kg/m2 or who weigh <400 pounds.

Exclusion Criteria:

  1. Pregnancy or lactation, since contraindicated for weight loss or affecting weight status
  2. Weight loss > 10 pounds in the previous 3 months
  3. Current use of weight loss medications
  4. Use of medications known to result in significant weight gain (e.g., oral steroids or second generation anti-psychotics)

  7. Unstable renal, hepatic, or cardiovascular disease, including malignant arrhythmias
  8. Recent (past 3 months) history of myocardial infarction, stroke, or congestive heart failure
  9. Participants age < 18 will be excluded because we are only using adult practices and a different type of program would be needed for patients < 18, and age > 70 years will be excluded because our experience has been that a specially tailored program would be needed. As a design consideration, we wanted to decrease the heterogeneity of the program.
  10. Participants with a BMI > 55 kg/m2 will be excluded because they are likely to require more extensive medical and behavioral care than can be provided in this study.
  11. More than 1 participant residing in the same household will be excluded to avoid contamination across the treatment conditions.
