The Proven Plan

Slim•Fast: supported by 45 clinical studies

The Slim•Fast plan is evidence based and the only diet plan on the market today that is supported by 45 published clinical studies in peer-reviewed journals. These studies demonstrate that following the Slim•Fast plan is not only effective for short-term weight loss, but also for long-term weight management.

Studies show:

  • Groups using a meal replacement-based diet plan consistently had significantly greater weight loss (7% to 8% initial body weight at 3 months and at one year) than those following traditional reduced-calorie diets.
  • Individuals who lost weight following the Slim•Fast plan showed improvements in mitigating the health risks associated with obesity, including type 2 diabetes, cardiovascular disease and osteoarthritis.
  • Following the Slim•Fast plan promotes improved food choices, such as increased fruit and vegetable intake, along with a healthy lifestyle with regular physical activity.
  • Results of a landmark community study examining the effectiveness of Slim•Fast in long-term weight management reported that individuals following the Slim•Fast Diet showed sustained weight loss for a period of 10 years (on average, a 33-pound difference for Slim•Fast users versus the non-Slim•Fast users).1
