Carbohydrate Blockers

Timeless Nutrition Tip

With the popularity of low-carbohydrate diets, supplements called carbohydrate blockers are suddenly everywhere.

Carbohydrate Blockers

The claim: . One or two tablets with a meal can block the absorption of about 400 calories worth of bread, pasta or potatoes. But do they really work?

The main ingredients are bean and wheat germ extracts thought to stop carbohydrate absorption by inhibiting a digestive enzyme that breaks down starch.

If starch passes through you undigested, you should lose weight.

However, evidence supporting this claim can be sketchy. Previous studies showed that the bean extract had no effect on calorie absorption or body weight. But recently, researchers at the Mayo Clinic found that higher doses of bean extract (4,000 to 6,000mg) and wheat germ extract (4,000mg) slowed carbohydrate digestion. These higher doses are not available in commercial carb blockers.

Plus, no one knows whether slowing carbohydrate digestion actually causes weight loss over time. So while the jury is still out on these, many people who try them say they do help. Some say VERY much, other say enough to curb their appetite to keep them from snacking. From what we've learned by those who use carb blockers, individual results can vary based on eating habits, lifestyle, etc.

One thing that seems certain amongst all experts is that trying them is safe.
