Carb blockers are marketed as weight loss products. The idea is they contain phaselous vulgaris which is extracted from a type of kidney bean.

This chemical is said to stop the enzyme alpha-amylase from breaking down those carbohydrates you’ve consumed.

Instead of ending up in your bloodstream, the carbs end up not being usable and so they are excreted with the rest of the waste from the body.

Because the carbs never enter your bloodstream, they won’t be saved up or converted into body fat later.

Additionally, your body will have to use the reserves you’ve already stored which can help you lose weight.

Side Effects

Because the carbohydrates are excreted from the body, most of the side effects are related to your bathroom habits. Users have reported problems such as excessive gas and diarrhea, as well as other types of “gastrointestinal distress.” You may also have severe heartburn.
