Brief Summary:
Behavioral obesity treatment (BOT) produces clinically significant weight loss and health benefits for many individuals with overweight/obesity and cardiovascular disease (CVD). Yet, about half of patients fall short of expected outcomes and most experience gradual weight regain, thus negating the benefits over time. Lapses (i.e., self-reported eating instances that deviate from the BOT prescribed diet) could explain poor outcomes, but the behavior is understudied because it is difficult to assess in-lab and via self-report. The investigators therefore propose to study lapses using a multimethod approach with the following tools: ecological momentary assessment (EMA; repeated sampling method via mobile device), a wrist-worn device that automatically detects eating behavior and various eating characteristics (frequency, rate, and duration of eating episodes), and 24-hour dietary recalls. The investigators will recruit participants (n=40) with overweight/obesity and one additional CVD risk factor to enroll in a 12-week BOT program and an additional 12-week period of weight loss maintenance. Participants will complete a biweekly 7-day EMA protocol to self-report on eating behavior, including the occurrence of dietary lapse. Participants will continuously wear the wrist-worn ActiGraph Link to characterize eating behavior. Lastly, participants will complete 24-hour dietary recalls via structured interview (split between days with and without lapses) at 6-week intervals to measure the composition of all food and beverages consumed. This study aims to 1) identifying characteristics of lapse behavior by measuring passively-sensed timing, duration, frequency, and rate of eating amongst known lapse episodes, 2) test the association between dietary lapse frequency and weight change, and 3) estimate nutrition composition of dietary lapses. The study approach is consistent with priorities of NHLBI to optimize clinical research and diagnostic strategies to improve CVD and related risk factors.

Self-monitoring. Participants will be taught to record their weight, the calories of each food item, and physical activity using a method of their choice (e.g., commercial smartphone app, paper diary). The clinician will review dietary intake and provide personalized feedback at the outset of session.

Diet. Per national guidelines for weight loss, a daily goal of 1200-1800 kcal/day will be prescribed depending on baseline weight. A Mediterranean diet will be prescribed to meet the recommended calorie goal and be consistent with dietary recommendations for CVD patients.

Exercise. Participants will be encouraged to achieve 250 minutes/week of moderate intensity activity in accordance with current national recommendations for physical activity among individuals attempting weight loss. Participants will be encouraged to gradually increase activity level to achieve approximately 50 minutes of activity over five days per week.

Other Name: Behavioral Weight Loss

Primary Outcome Measures :
  1. Sensor-based Dietary Lapse [ Time Frame: 24-week frequency of sensor-based dietary lapse ]
    Participants will wear a wrist-worn 9-axis accelerometer during waking hours that measures wrist-roll motion, which can objectively assess dietary lapses.

Secondary Outcome Measures :
  1. Self-reported Dietary Lapse [ Time Frame: Participants will be asked to complete 7 days of EMA on a biweekly basis for 24 weeks. Therefore, participants will complete EMA at weeks 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, and 23. ]
    Lapses will be assessed via ecological momentary assessment (EMA), a repeated sampling method using electronic forms on smartphone devices.

  2. Weight [ Time Frame: Weight will be measured at each study appointment (baseline assessment, weekly for 12 weeks, and twice monthly for the subsequent 12 weeks). ]
    Participants' body weight will be measured to the nearest 0.1 kg using a calibrated digital scale

  3. Dietary Composition [ Time Frame: Dietary composition will be assessed at baseline and at weeks 5, 11, 17, and 23 ]
    Dietary composition will be assessed using 24-hour food recall method. The Nutrition Data System for Research (NDSR), a computer-based software application developed at the University of Minnesota Nutrition Coordinating Center (NCC) will facilitate the collection of recalls in a standardized fashion
