Primary Outcome Measures:
  • Changes in weight [ Time Frame: weeks 4, 12, 24 and final weight loss visit (average of 19.6 weeks) ]
    Weight loss (in pounds and percent weight loss) at weeks 4, 12, 24 and at final weight loss visit (average of 19.6 weeks).

  • Changes in body composition [ Time Frame: weeks 4, 12, 24 and final weight loss visit (average of 19.6 weeks) ]
    changes in lean muscle mass, body fat mass, and body fat percent at weeks 4, 12, 24, and final weight loss visit(average of 19.6 weeks).


Secondary Outcome Measures:
  • Compliance [ Time Frame: weeks 4, 12, 24 and final weight loss visit (average of 19.6 weeks) ]
    Compliance is measured by client attendance at weekly visits, consumption of meal replacements and dietary supplements, ketone testing, and completion of food journals

  • Retention rates [ Time Frame: weeks 4, 12, 24 and final weight loss visit (average of 19.6 weeks) ]
    Retention of clients at specified time points (weeks 4, 12, 24 and final weight loss visit) and during the transition and weight maintenance phases of the MWCC weight management program

  • Goal weight achievement [ Time Frame: Final weight loss visit (average of 19.6 weeks) ]
    The percent of clients that achieve thier goal weight by their final weight loss visit(average of 19.6 weeks)

  • Changes in abdominal circumference (inches) [ Time Frame: weeks 4, 12, 24 and final weight loss visit (average of 19.6 weeks) ]
  • Maintenance of weight loss [ Time Frame: Following transition (up to 12 weeks) and maintenance (up to 52 weeks) phases of the program ]
  • Changes in cardiovascular risk factors [ Time Frame: weeks 4, 12, 24 and final weight loss visit (average of 19.6 weeks) ]
    Improvements in diastolic and systolic blood pressure and pulse at weeks 4, 12, 24 and final weight loss visit (average of 19.6 weeks).

Groups/Cohorts
MWCC clients
This study will be a systematic retrospective chart review of clients participating in the Jump Start (5 & 1) Plan at three different MWCC locations in Texas during the years 2007 - 2010.

Detailed Description:
Portion-controlled meal replacements by themselves have been shown to be an effective weight control strategy in overweight and obese individuals. The addition of medical supervision has been shown to result in greater weight loss than meal replacements alone. MWCC provides this added support through individual weekly counseling sessions. Thus, the investigators plan to retrospectively evaluate the efficacy of the MWCC Jump Start (Medifast's 5 & 1) Plan on the following indices: weight loss, anthropometric changes, and reduction in common markers of coronary heart disease.
