Question / Intervention Goal / Objectives

The 20Lighter Program is a physician-supervised weight loss intervention.  The program provides meal plans, dietary supplements, and offers participants daily interaction with a physician via a smart phone.  The program consists of three phases: a loading day, six weeks of low-calorie meal plan, and three weeks of transition to normal dietary intake.

Reduction in visceral fat and weight are the main outcomes measured in a population of 2,200 men and women who completed the program.   Maintenance of the weight loss was monitored 18 months after program completion.

 

Method/ Calculation

The data source is device-recorded body weight and visceral fat at baseline, 20 days, 40 days, and 60 days after program start.  Calculation of percentages was performed by the biomedical device.

A survey was sent to participants to assess their change in weight status 18 months after the program ended.

 

Findings / Metric/ Outcome/ Savings

Participants had statistically significant reduction in visceral fat, a recognized indicator of cardiovascular disease risk, at the 60-day measurement; this compared baseline measurement to the 60-day measurement.

Fifty seven percent of the participants responded to the 18-month follow-up survey.  The percentage of respondents who said they had maintained their weight loss or had lost more weight was 70%.

 

Limitations

The data is limited to people who completed the program, omitting those who dropped out.  Data was not shown about the initial enrolling group.

The survey response rate of 57% is high; non-respondents received three follow-up reminders which could strengthen the results.  No analysis was done about non-respondents to determine a pattern of non-response.

The follow-up survey was not a validated instrument, which makes the results less reliable than is ideal.

The analysis did not include actual medical costs incurred by program participants; thus, while certain disease risk factors may be lower, medical costs may or may not be changed as a result.
