Can a “diet” snack bar really help you lose weight? Well, you first need to consider what is in the product, and how you are using it or incorporating it into your diet plan. If you simply add snack bars or protein supplements to your current diet, then you will not lose any weight, but you will likely gain a few pounds. The key is to replace snacks and meals that are higher in calories. One product that is intended for this is the Slim-Fast 3-2-1 Plan Bar. We will now take a closer look at what this bar has to offer. We are examining the chocolate brownie flavor option.

Product Features

The Slim-Fast 3-2-1 Plan Bar is available through some online drugstores for $6.99 (five bars). It is intended to suppress your food cravings, provide protein and fiber, and help you with weight loss. Note that if you eat too many of these bars, you might experience a laxative effect. After all, they contain several sweeteners.

A single Slim-Fast 3-2-1 Plan Bar provides 200 calories, four grams of fat, 140 milligrams of potassium, 32 grams of carbohydrates, five grams of dietary fiber, 13 grams of sugar, and eight grams of protein. You should also be aware that this bar does contain soy, wheat, and milk, and may contain nuts, eggs, and coconut.

Most people are familiar with Slim-Fast weight loss products. They are typically easy to come by in local stores, which is handy. However, the Slim-Fast 3-2-1 Plan Bar does not come across as the most promising meal replacement or snack bar for dieters. Not only does it only offer eight grams of protein per serving, but it also contains several sweeteners that can lead to diarrhea, which no one wants.
