I've been taking UltraClear Plus Medical Food from Metagenics for several weeks and the first thing that I liked about it was how good it tasted. It's sweet so subconciously, you feel like you're snacking or just eating something that you shouldn't be. That's actually how it makes you want to take it in the first place. It really quenches my craving to always eat, or just eat food that I can't. Therefore, when I'm not in the mood or haven't eaten a solid meal, I take this to give me a proper meal. I haven't gotten any stomach or gas problems from it. In fact, UltraClear Plus Medical Food only makes me feel good. Lately, I've decided to take it in place of two meals and just make my own dinner. As a result, over the course of two weeks, I've been able to lose 10 pounds!
