I just started to low carb on the advice of my doctor because I need to lose weight, my triglycerides are elevated, and my blood sugar is a little high (though not close to diabetes yet). I'm taking AM-300 with ephedra. I haven't had any bad side effects yet, so far it's good but it's only my second day. I feel like I have more energy to get things done around my house, that's for sure. And I even exercised today to my WATP video. It was recommended to me by a girlfriend who has used it for years and had wonderful results both in losing and keeping off pounds.
