Supplements: Should you take PGX?

There are so many supplements available that purport to be The Answer to quick and easy weight loss. Of course, if any of them were actually any good, overweight and obesity wouldn’t be a problem anymore. PGX is no different. A quick google search yielded a link to support from Dr. Oz. To me, that’s a huge red flag. If Dr. Oz is pushing it then my skepticism is definitely going to increase.

I went through PGX’s website which claims that it “will change your life”. The website makes several claims about the benefits of PGX, the first of which is that it helps you lose weight. How will it do this? Well, PGX is a viscous fibre and when consumed with water it will increase in bulk in your stomach. The idea is that you take PGX before a meal so that you’ll feel fuller and eat less. In theory, great. In practice, does it really work? Interestingly, while the PGX website makes the claim that their product assists in weight loss there is no link to research supporting that claim. Google scholar doesn’t provide much more information. A couple of studies claim that PGX may be beneficial for blood glucose control and another asserts that it may be useful for short-term weight loss. However, there is nothing to support long-term weight loss and all of these studies were supported by the makers of PGX so I’m inclined to take them with a grain of salt.

While PGX appears to be a safe product, it also appears to be an¬†unnecessary one. Yes, many people could stand to increase the amount of fibre they’re consuming but they’d be better off doing that by adding whole grains, fruits, and vegetables to their diets.

As with most of these weight loss products, PGX is only effective when combined with a healthy diet and exercise. Hmmm… What would happen if you removed PGX from that equation? I’m guessing the same amount of weight loss, although maybe a little less as your wallet wouldn’t be any lighter.
