Aletta, Smart for Life Hungerblock Weight Loss Aid reports to help curb appetite. It contains vitamins including B's, C, Biotin, choline, and a few other things. I tried it out of curiosity. Honestly, it made no difference in my appetite what so ever. In all honesty, weight loss is best achieved by eating whole foods, exercise, hydration and sleep. A recent study showed that those who get 8 1/2 hours sleep lost 54% more body fat than those who slept 5 1/2 hours. They also experienced significantly less hunger. So try a few extra hours of sleep and make sure you are eating enough! Good luck on your journey.
