Do Carb Blockers Really Work?
If you've got a few pounds to lose, you've probably been tempted by the claims of one of the numerous carb blocker products on the market these days. Some of the more outrageous ones include the all-too-common "eat all you want and still lose weight!" This apparently, is facilitated by the carb blocker's ability to block the absorption of carb calories into the body. While this certainly sounds good, the question really is...

No surprise here. Anyone who statesthat you can "eat all you want and still lose weight"obviously does not have your best interests at heart.
But what about "scientific claims" these manufacturers useto validate their claims? It's shoddy at best. Here's anexcerpt from the FDA press release that announced its intentto pursue 16 manufacturers of such products...

The most common ingredient in "carb blockers" is whitekidney bean extract, or phaseolus vulgaris. In vitrostudies showed that phaseolus vulgaris inhibited theactivity of an enzyme called alpha-amylase, which is neededto break starches down into the simple sugars that areeasily absorbed by the body. But it's too early to claimmiraculous weight loss effects in humans. In fact, a recent UCLA clinical study on phaseolus vulgaris concluded...
"Clinical trends were identified for weight loss and adecrease in triglycerides, although statistical significance was not reached."
In other words, white kidney bean extract looks promising,but its effects are hardly earth shattering. To emphasize this, Food and Drug Administration (FDA) has sent warning letters to 16 dietary supplement distributors making false and misleading claims for weight loss products promoted over the internet...

Many of these are "carb blockers."
Save your money. I rest my case.
