I've been using this product for only three weeks, but so far it seems like the answer to my prayers. It seems to be composed of healthy ingredients, tastes OK, especially combined with strawberries, seems to not have any side effects, relatively easy to prepare (relatively, because I work full time and I don't have access to a blender at lunch.) As soon as I had just one or two shakes, I noticed that food carvings no longer torture me all day. And the effect (lack of cravings) is still here after 3 weeks.
I lost 4 lbs in 3 weeks, which in my case is 2.5% of total body weight - no need to lose faster.
Before that, I tried every non-wacky diet and many other products, only to struggle, not lose any weight, and get really hungry in the end.
Oh, and on top of that, my sleep and mood improved.
