Carb blockers work differently than other weight loss pills on the market. They block carbohydrates from being digested, which means it could allow you to eat carbs without some of the unwanted calories.
What Are Carb Blockers?
Also known as starch blockers, carb blockers help block the enzymes we need to digest certain carbohydrates. They are made from alpha-amylase inhibitors, which naturally occur in certain foods.
Oftentimes, these compounds are extracted from beans and referred to as Phaseolus vulgaris extract or white kidney bean extract. Prescription medications called alpha-glucosidase inhibitors are used to treat blood sugar levels in Type 2 diabetics.
How Do Carb Blockers Work?
Digestible carbohydrates can be split into two groups — complex and simple carbs.
Simple carbs are found in fruits and milk products. They are also found in processed foods like flavored yogurts, desserts, and sodas. Complex carbs are found in bread, pasta, and starchy veggies like potatoes.
Complex carbohydrates are made up of many simple carbs that link together to form chains. These chains need to be broken down by enzymes before they can be absorbed. Carb blockers inhibit some of these enzymes that break down the complex carbs.
This results in those carbs passing into the large intestine without being broken down or absorbed. They won't add to your calories or raise your blood sugar levels.
Several studies suggest carb blockers may help with weight loss.
Carb blockers may affect some of our hormones that are involved in hunger and fullness. One reason for this is because the bean extracts also contain phytohaemagglutinin, which is a compound that can increase the levels some hormones involved in fullness.
Some researchers also believe carb blockers can suppress the levels of ghrelin.
Carb blockers may help with losing weight, but they have a bigger impact on your blood sugar control. They prevent or slow down the digestion of complex carbs, so this lowers the spike in your blood sugar levels.
