Is it really useful to use medical treatment or medicines to loss my weight?

Use of medical gives side effect or it is good to use?

I believe ephedra, which there was a cheap natural version that got maligned and suppressed that works very well. There are synthetic versions that are much more dangerous.
But I've heard that cleanses are the beast place to start. Candida yeast cleanse, colonics, parasite cleanse, liver kidney gall bladder.

Using the glycemic index might be a lot easier and safer.
