Investigators from the University of California-Los Angeles (UCLA) and The Children's Clinic of Long Beach (TCC) are conducting a randomized, controlled comparative effectiveness trial of two government-sanctioned behavior change approaches to weight control with TCC's obese patients. The first approach is the calorie-counting calorie restriction (CC) approach used in the Diabetes Prevention Program. The second approach is the high-satiation/high-satiety approach represented by MyPlate.gov. The MyPlate nutritional goal is to double patient fruit and vegetable intake, legume intake, and whole grain intake. Both conditions stipulate 150 minutes of moderate physical activity a week. Study participants will be 300 of TCC's obese patients, 76% of whom are expected to be Latino, 13% African American and 11% Other Ethnicities.
The interventions will be implemented by trained community lifestyle change coaches with brief support from clinicians. The interventions will include two home visits, two group education sessions and seven telephone behavior change coaching sessions.
Compared to the CC approach, the MyPlate approach is hypothesized to yield better 12 months patient-centered outcomes, particularly self-reported satiety.

Active Comparator: Calorie-counting
Intervention protocol adapted from Diabetes Prevention Program lifestyle change intervention.
The Calorie Counting (CC) condition asks obese patients to achieve a daily calorie deficit. For average women consuming 2,000 calories at baseline, the target daily calorie total might be 1,600 calories. Participants are also asked to do at least 150 minutes of moderate to vigorous physical activity per week.
Two community health workers will provide behavior change coaching to 150 TCC obese patients randomly assigned to the CC condition. The intervention protocol is adapted from the Diabetes Prevention Program. Behavior change strategies include: self-monitoring (e.g., calorie-counting, self-weighing), stimulus control, and relapse prevention strategies. The health coaching will occur during two home visits, two group health education sessions, and 7 telephone coaching calls.
Other Name: DPP intensive lifestyle change intervention
Intervention protocol adapted from Dietary Approaches to Stop Hypertension dietary pattern.
The MyPlate approach asks Americans to limit daily calories but emphasizes eating MORE high-satiation foods by making ½ of daily food choices fruits and vegetables,¼ of daily food choices whole grains. All participants are asked to do at least 150 minutes of moderate to vigorous physical activity per week.
Two community health workers will provide behavior change coaching to 150 TCC obese patients randomly assigned to the MyPlate condition. MyPlate is adapted from the DASH protocol. Behavior change strategies include: progressive goal-setting, stimulus control, and self-monitoring (e.g., % of food choices that are fruits & vegetables). The health coaching will occur during two home visits, two group health education sessions, and 7 telephone behavior change coaching calls.

- Patient-centered Outcome Measure = Self-reported Hunger [ Time Frame: 12 months follow-up ]Response to question: "Thinking about yesterday, how hungry did you feel during the day?" Response was a mark on a 100mm scale or oral response on a scale from 0 to 100 (for participants assessed via phone), 0="Not at all hungry" and 100="Extremely hungry."
- Medical Outcome Measure = Body Weight [ Time Frame: 12 months follow-up ]Body weight, measured in kilograms, was obtained by having shoeless participants dressed in light clothing stand on a regularly calibrated medical scale. Measures were taken twice. If these measures differed by more than 0.2 kg, a third measure was taken and averaged with the other two.
- Meal Satisfaction Yesterday [ Time Frame: 12 months follow-up ]"Take a moment to think about the last meal you ate yesterday. Thinking about the last meal you ate, how satisfied were you after the meal?" Response was a mark on a 100 mm visual analogue scale or response to oral question on a scale from 0 to 100 (for participants assessed via phone), with the low end (0) anchored by "Very satisfied" and the high end (100) anchored by "Very unsatisfied." For analysis purposes this measure was reverse-scored, so that higher values represented greater meal satisfaction.
- Feeling Full After Last Meal Yesterday [ Time Frame: 12 months follow-up ]"Take a moment to think about the last meal yesterday. Thinking about the last meal you ate, how full did you feel after that meal?" Response was a mark on a 100 mm visual analogue scale (VAS), or oral response to question on a scale from 0 to 100 (for participants assessed via phone), 0="Extremely full" and 100="Not at all full." For analysis purposes this measure was reverse-scored, so that higher values represented greater fullness.
- Systolic Blood Pressure [ Time Frame: 12 months follow-up ]Systolic blood pressure assessed on participant's left arm while participant is seated, after at least 5 minutes of rest. Automated, regularly calibrated sphygmomanometer was used with oversize cuffs for obese arms.
- Body Mass Index [ Time Frame: 12 months follow-up ]Body mass index is weight in kilograms divided by the square of the participant's height measured in meters. Wall-mounted stadiometer was used to assess height. Weekly-calibrated, portable, digital scales were used to assess body weight.
- Waist Circumference [ Time Frame: 12 months follow-up ]The waist circumference was assessed using research standard waist circumference measuring tapes. The result was measured to closest 0.1 cm. The assessor was instructed to position the measuring tape horizontally around the waist, just above the iliac crest.
