What Are Carb Blockers?

Carbohydrate blockers, also known as starch blockers, or carb blockers, suppress the enzymes essential for carbohydrate breakdown.

They consist of alpha-amylase inhibitors, found naturally in a variety of foods. Others come in the form of prescription drugs for type 2 diabetics who have excessive blood sugar.

They render the starches indigestible, converting a molecule that would normally provide a few calories and boost blood sugar into a static material that passes through our digestive tract.

A lot of people praise carb blockers claiming that they assist in rapid weight loss when combined with a balanced diet and exercise routine.
