The Slim-Fast Diet says that anyone can lose weight if they simply restrict their daily calorie intake. However, they also claim this can be done with great diversity which they prove with a large variety of shakes, meal bars and snack bars.

Slim-Fast is designed to replace a lot of your daily calories with their snacks and shakes. You are allowed 1,200 calories each day on the diet which will come from two servings of Slim-Fast products, one snack (typically a fruit) and a regular 500 calorie meal that you prepare at home. This allows those on the diet to still be able to enjoy some of their favorite foods, though only once a day and in smaller quantities.

Do Dieters Lose Weight on the Slim-Fast Diet?

Dieters who stick to the Slim-Fast regimen will lose weight. This will be largely due to the fact that the daily calorie intake is only 1,200. While the program is recommended for those who have to lose 20 or more pounds, it is only the strict dieter who will lose weight with Slim-Fast in the long run. This is easier for some, but those who prefer to have a larger portion of food with each meal might have trouble sticking to the diet without cheating in excess.

Is the Slim-Fast Diet Easy to Follow?

Slim-Fast is a diet that is convenient, but it isn’t the easiest one to follow. While the snack bars and shakes are plentiful as far as variety goes, they can easily become mundane. Dieters who attempt to stay on the Slim-Fast Diet on a long-term basis may therefore have some trouble staying true to the diet.

Like any other diet, when you become bored with the routine, you are more likely to cheat. When too much cheating occurs then much of the achieved weight loss can be reversed and in some cases more can even be gained.


The cost of the Slim-Fast Diet all depends on which of the offered meals you purchase and how much of each meal you purchase. Many stores now carry individual shakes as well as meal and snack bars.

This is again convenient, but can also be costly. For the most part, those wishing to partake in the Slim-Fast Diet are better off buying their shakes and meal and snack bars in bulk as a 24-pack of shakes runs around $35 and a 24-pack of certain snack bars can be as little as $17.

The Slim-Fast Diet highly recommends those who are on the diet to be very active. Their recommendation is to work out at least 30 minutes per day most days of the week. While the commitment of physical activity expected is great, they do say that the exercise doesn’t need to be extremely strenuous. Slim-Fast also helps those who want to get started with their exercise regime by providing helpful tips online at their website.
