Carb Bloc is a weight loss supplement manufactured by Ultimate Nutrition that is supposed to block the body’s attempt at digesting those nasty carbs that, despite our best efforts, we just can’t seem to say no to.

Does It Have Any Redeeming Qualities?

Carb Bloc relies solely upon the powers of white kidney bean extract to inhibit the absorption of carbohydrates within the small intestine. Although there hasn’t been extensive research done on the effects that white kidney bean extract can have on weight loss, there have been some studies that have shown positive results. One in particular, took sixty slightly overweight people and had them supplement their diet and exercise program with either the extract or a placebo. The results were that thirty percent more of the people within the white kidney bean extract group saw weight loss than those who were in the placebo group.

Anything To Be Worried About?

Although these results are bolstering, they don’t exactly mean that we should all rush out and buy a supplement like Carb Bloc that uses white kidney bean extract. Science is quite sure that white kidney bean extract does have some stalling effect on the digestion of carbohydrate, although not everyone believes this leads to the positive outcome of weight loss, but they are also sure that this stalling effect has negative outcomes elsewhere in the body. For example, when these undigested carbs reach the large intestine, they start to ferment, which gives off gas which means—yep, you guessed it—bloating and diarrhea.

Would You Recommend Carb Bloc?

Even if Carb Bloc can offer you an extra boost in your weight loss attempts, the benefits might not be worth the side effects. In fact, even those who saw weight loss results using a carb blocker discontinued using the product early on because the ills of the product were simply too much to bear.
