If my over-simplification implied the fact that I was insulting you, it was not my intention.

I do not have your labs, nor am I privy to your long-term glucose levels. Taking this into consideration, my best guess would be that your rapid weight loss is a combination of things, primarily water.

Now...I'm not saying you arent losing fat. You probably are, and probably will continue to do so...but not 7lbs worth in 1 week.

I'm just saying you need to be careful, choose a more realistic diet, and watch your levels closely. You don't need pills to lose weight.

The ONLY way to lose weight is to burn more calories than you eat. Period.
