How Does the Slim-Fast Diet Work?

Meal Replacement

Slim-Fast products act as meal replacements. You can choose from various products, such as ready-to-drink or powdered shakes, snacks, frozen treats and bars. To follow the program, eat a Slim-Fast meal replacement product instead of breakfast and lunch. Then, according to the Slim-Fast website, you should eat a "sensible" dinner in the 500 calorie range. The website helps Slim-Fast users create appropriate personalized meals. The Slim-Fast diet also includes two snacks, which can be Slim-Fast products or healthy items like fruit or low-fat yogurt.

Portion Control

The Slim-Fast diet is meant to be used on a temporary basis. It helps users reduce their calories and learn portion control as they shed unwanted pounds. Once they return to eating three regular meals, they should be better at making healthy choices so they do not regain the lost weight.

Exercise

Ideally, the Slim-Fast diet plan should include exercise. This will accelerate the weight loss while following the plan and help keep the pounds off after a person stops using Slim-Fast.

Support

Slim-Fast has a website that has many weight-loss tools for users. These include meal planners, fitness program planners and a weight loss calculator. It also maintains a user community where people an interact with other Slim-Fast users and get and provide support. This includes sharing of recipes and goals and advice on things like how to control cravings or how to eat healthy restaurant meals.

Results

A study published in "Obesity Research" showed that people who used the Slim-Fast diet lost weigh and kept it off for the long term. The study, which ran for a decade, found that participants who used Slim-Fast were an average of 33 pounds lighter than non-users at the end of the ten-year period. The Free Dieting website says this is one of the longest studies ever to be conducted on a particular weight loss program.
