Slim-Fast Meal Replacements Diet Plan
Weight Loss Study Summary
Slim-Fast Meal Replacement Plan Shown to Result in Significant Weight
Loss at Six Months, Weight Maintenance for 10 Years. Study participants
who routinely used the Slim-Fast meal replacement plan maintained an average
weight loss of six pounds after 10 years while those in the matched group
gained an average of nearly 27 pounds over the same time period.
Weight Loss Study Method
In the Slim-Fast group, men maintained an average weight loss of 7 pounds
and women an average loss of 5.3 pounds over the 10-year period of the
study. In the matched group, men gained an average of 25 pounds and women
gained an average of 28 pounds, meaning the average weight of those in
the matched group was 32.6 pounds greater after 10 years than the average
weight of those in the Slim-Fast group. Body weight was documented twice
annually during each year of the study. Study participants were also encouraged
to increase their physical activity.
Weight Loss Study Method - 10 Years
Later
After 10 years, 130 participants (44 men and 86 women) in the Slim-Fast
arm and 154 participants in the matched group were evaluated. Matched
group participants, who did not participate in the meal replacement plan,
were matched with those in the Slim-Fast study on the basis of body mass
index (BMI), age, sex, and race at the onset of the study.
Weight Loss Study Method - Portion Controlled
Meal
To lose weight, those in the meal replacement group substituted a portion-
controlled Slim-Fast meal or snack replacement for two regular meals and
one of three daily snacks. To maintain weight, participants replaced one
meal and one snack with Slim-Fast product. They were instructed to return
to the weight loss plan of two meal replacements per day if they regained
weight. Slim-Fast products were provided to those in the meal replacement
study without cost.
