I've never used that. With my health problems, I can't use supplements before checking with my nephrologist. And I don't care for Dr Oz pushing all these supplements (my opinion). It's as if he now works for the companies making them.
I always think about what Oprah said years ago. She said there are no supplements that help with losing weight. She said that she can afford to use or try anything, but nothing works like watching what you put in your mouth. So...I watch her to see if she's discovered something new. But so far, no, it doesn't appear that she has!
Once in a while I'll hear some people saying to drink lemon juice or apple cider vinegar with your meals and it will "eat" the fat. That's something people tried in the 70's and I guess it's back! Doesn't work!
I'm trying to accept being padded. Been this way for 30 years and yes, for me it's next to impossible to lose much weight as I'm older AND find it difficult to give up cookies, etc!
