Jump Start, USANA
Brief summary
The purpose of the proposed study is to evaluate the impact of the Jump Start program to facilitate weight loss in a sample of overweight and obese men and women. The study will not only evaluate weight loss and changes in body-shape but will also assess the type of weight lost (fat vs. lean mass) and other health measures affected by obesity including lipids, glucose, insulin, resting heart rate and blood pressure, and perceived wellness. This study will contribute to the general weight loss literature by providing evidence for or against the use of a meal replacement centered one-week weight loss program to yield weight loss and other health-specific benefits. The hypothesis is that the Jump Start program will result in an average 3-5 pound weight loss, as well as improvements in bloodborne markers of health, from day 1 to day 8.
