  • Ages 18 years and older
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: 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.

Who may be able to join

  • 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.

Who cannot join

  • 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.

About this study

Official title: A Retrospective Chart Review to Assess Weight Loss in Overweight and Obese Adults Using Either the 5 & 2 & 2 Meal Replacement Plan or the 4 & 2 & 1 Meal Replacement Plan at Medifast Weight Control Centers

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • 5 & 2 & 2 PlanOther

    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 PlanOther

    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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  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.).

Questions about this trial

What is this clinical trial studying?

An observational study of Obesity, run by Medifast, Inc. at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 13 Sep 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 13 Sep 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Body Weight (time frame: 12 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02150837, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Sep 2019.
