Retrospective Chart Review of the 5 & 2 & 2 and 4 & 2 & 1 Plans

Brief Summary
The purpose of this study is to retrospectively and systematically review records of overweight and obese Medifast Weight Control Center (MWCC) members who have been assigned to the 5 \& 2 \& 2 Plan or the 4 \& 2 \& 1 Plan for weight loss to gain a better understanding of the effectiveness of these programs. The study will describe demographics of this population, along with weight loss, anthropometrics, body composition and effects on available cardiovascular parameters. Adherence to the plans will also be examined. The study hypothesis is that the 5 \& 2 \& 2 Meal Replacement Plan and the 4 \& 2 \& 1 Meal Replacement Plan are both effective programs for weight loss in overweight and obese adults.

Outcome Measures
Primary Outcomes (1)
Body Weight
The primary endpoint in this study is weight and the primary outcome is change from baseline body weight at 12 weeks for each plan (5 \& 2 \& 2 and 4 \& 2 \& 1 Plans). Change from baseline will also be examined at other predetermined time points (e.g., 1, 2, 4, 8, 16, 20 and 24 weeks, and final weight loss visit - the mean length of time from baseline to the final weight loss visit was 18.06 weeks for the 5 \& 2 \& 2 Plan and 17.35 weeks for the 4 \& 2 \& 1 Plan.).

Study Arms (2)
5 & 2 & 2 Plan
MWCC members who used the Medifast 5 \& 2 \& 2 Meal Replacement Plan for weight loss.
4 & 2 & 1 Plan
MWCC members who used the Medifast 4 \& 2 \& 1 Meal Replacement Plan for weight loss.
Interventions
Medifast has developed the 5 \& 2 \& 2 Plan as a higher calorie and higher carbohydrate alternative. This plan may be selected for very obese (BMI ≥ 40kg/m2) or older (\>65 years) individuals, or for medical (e.g., diabetes) or behavioral reasons (individuals engages in high levels of physical activity). The 5 \& 2 \& 2 Plan consists of 5 Medifast meal replacements, 2 Lean \& Green meals, and 2 healthy snacks and provides 1,200-1,400 kcal, \>72g protein, \>100g of carbohydrate, and \<30% of calories from fat. The Lean \& Green meal is consumer selected and consists of 5-7 ounces of a lean protein, 1 ½ - 3 cups of non-starchy vegetables, and up to 2 healthy fat servings. The healthy snack(s) included in this plans consists of a consumer selected serving of grain/starch, dairy, or fruit.

Eligibility Criteria
This study is a systematic retrospective chart review of existing MWCC charts located in Maryland, Texas, Florida or Pennsylvania for MWCC members who used either the Medifast 5 \& 2 \& 2 Plan or the Medifast 4 \& 2 \& 1 Plan for weight loss. Charts will be reviewed for members that started either the 5 \& 2 \& 2 Plan or the 4 \& 2 \& 1 Plan on or after January 1, 2012. This start date was chosen because it represents the date when Medifast began using the current versions of the 5 \& 2 \& 2 Plan and the 4 \& 2 \& 1 Plan. Only charts of those members who are no longer in the active weight loss phase of their program at the MWCC will be considered for the study.
You may qualify if:
- Adult males and females, 18 years of age or older at the start of the weight loss program.
- Subject has a BMI ≥ 25 kg/m2.
- Subject started a weight management program at the MWCC location on or after January 1, 2012.
- Subject followed the 5 \& 2 \& 2 Plan or the 4 \& 2 \& 1 Plan for at least the first two weeks of their weight loss phase while an active member of the MWCC.
- Subject signed the Personal Health Information Consent Form.
You may not qualify if:
- Subject was concurrently following another weight loss program other than the 5 \& 2 \& 2 Plan or the 4 \& 2 \& 1 Plan while on that respective plan.
- Subject had documented use of prescription or over-the-counter weight loss pharmacotherapy (e.g., phentermine, Orlistat) concurrently with the 5 \& 2 \& 2 Plan or the 4 \& 2 \& 1 Plan.
- Subject completed initial consultation but did not participate in any follow-up visits.
- Subject is currently in the active weight loss phase of their program at the MWCC (Subjects in the transition or weight maintenance phases of their programs are eligible.)
- Written request by subject to revoke consent to use health information is present in subject chart.
