People Be careful with the likes of xenical!! If I recollect correctly, one of the weight loss products, acomplia is the name, has been removed as it was proven to be quite risky to take.
Xenical is a prescription-only medicine , and you must be over a certain BMI ranging near the morbidly obese category, have no health issues, and the important part for people on Atkins is that it does not cope well with fat in foods.
Lots of fat increased diarrhea, as its main function is to "inhibit" fat uptake in our body, and unprocessed fat ends in stools..
So, Xenical is not good for people on Atkins.
Do not look for magic pills, just try Atkins
