Carb Blockers: Do they really work?

on May 11, 2021

Why are carbohydrates getting a bad rap these days? What is wrong with bread and pasta? An apple is healthy, right? Ice cream, maybe not so much.

If we are not watching what we eat and consider our diet to be an 'average diet', we may be getting about half of our calories from carbohydrates! Carbohydrates, or Carbs, are a type of macronutrient found in many foods and beverages and they occur naturally in plant-based foods, such as grains. Many processed foods contain starch or a lot of added sugar, that is why we all reach for ice cream!

There are two types of carbs; simple carbs (sugars) and complex carbs (starch). Our body breaks down complex carbs with the help of digestive enzymes. Once the starch is broken down, other enzymes finish the job and these simple sugars can be absorbed into our small intestine. Many times these sugars are used for energy but sometimes they are stored as fat. Let's look at a triathlete, they may want the stored energy for daily training but most of us don’t need the extra layer of energy (fat).

When swimsuit season comes along, many of us seek out 'carb blockers'.

Here are a few of the tops reasons why carb blockers are popular:

  • Weight Loss
  • Decrease calorie intake
  • Control blood sugar

Let's start with what is a carb blocker? And more importantly, do carb blockers work?

Carb blockers for weight loss were introduced for those who like pasta! Carb blockers interfere with digestion and help decrease the calories we get from carbs. Carb blockers also help reduce spikes in blood sugar and insulin resulting in weight loss.

Xendurance included white kidney bean extract, a natural carb blocker, in their product Lean+. White kidney bean extract is best known as a “starch blocker” and helps minimize the breakdown of carbohydrates into sugars.

White kidney bean extract is one of the most popular and well researched carb blockers on the market. It works by inhibiting an enzyme called amylase which breaks specific bonds that hold starch together. In other words, when we go for that bowl of fettuccini, some carbs will pass through the digestive tract as if they are fiber, helping to improve blood sugar control and boost weight loss in people who derive the bulk of their calories from starchy foods and other complex carbs (not processed foods with simple sugars).

Xendurance's Lean+ formula was built to help block those carbs and stay “lean and mean” to easily slip into into that summer swimsuit!

Does this mean we can eat what we want?! Not exactly. While Lean+ contains other ingredients such as patented Forslean®, Chromium Picolinate and Green Tea Extract to provide support for losing weight while keeping lean muscle mass, we recommend taking this supplement alongside a well rounded whole food diet.
