There has recently been a great deal of online chatter about the FDA approving Alli as an over-the-counter drug. Alli is orlistat, often called Xenical. Several years ago, I took prescription Xenical for a couple of weeks. If you are not already on a super low fat diet, it makes life very unconfortable. And if you are already on a low-fat diet then why take the fat blocker? The label warns of diarriah. Well, it's a bit misleading. It's more like foul smelling vegitable oil coming out of your back end. It was so liquid and oily that it was difficult to hold in and had resulted in more than one "accident" during my two week trial. I don't recall having lost any weight while on this drug. Even if I did, it wouldn't have been worth it. As you can see in my blog, I am currently doing a low-carb diet with no diet pills. I've lost almost 70 pounds in six months. I'd imagine that since my diet is now a little higher in fat than before that if I were to add orlistat, I'd be unable to leave my bathroom.
