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