Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

5 & 2 & 2 Plan

MWCC members who used the Medifast 5 \& 2 \& 2 Meal Replacement Plan for weight loss.

5 & 2 & 2 Plan

Intervention Type OTHER

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.

4 & 2 & 1 Plan

MWCC members who used the Medifast 4 \& 2 \& 1 Meal Replacement Plan for weight loss.

4 & 2 & 1 Plan

Intervention Type OTHER

Medifast has developed the 4 \& 2 \& 1 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 4 \& 2 \& 1 Plan consists of 4 Medifast meal replacements, 2 Lean \& Green meals, and 1 healthy snack, providing 1,000-1,200 kcal, \>72g protein, \>100g 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 included in this plans consist of a consumer selected serving of grain/starch, dairy, or fruit.
