Although eating or drinking Slim Fast products does not guarantee weight loss, following the company's suggested meal plan may help you reduce calories and thus trim down. The program involves consuming Slim Fast meal bars or shakes for breakfast and lunch and then eating a healthy dinner. Snack bars or other low-calorie snacks are included in the plan, as well. If you thrive with structure and don't mind the relative lack of variety, Slim Fast may be an appropriate option for you.

Slimming Results

According to the company website, dieters can expect to lose 1 to 2 pounds per week on the Slim Fast plan. Most experts consider this a safe pace, according to Harvard Health Publications, and losing weight any faster may require too deep a cut in calories, leading to poor nutrition. The more you exercise on the plan, the faster you will lose weight. Slim Fast also notes that you should start to see results after the first week.
