I've tried for about 5 months. It works but it's better if you try loosing weight by eating healthier. It's really hard to substitute 2 meals for a shake. When you start you will feel satisfied but eventually you're going to start eating again maybe more. I lost like 15 pound with herbalife but I gained 25 pounds later. (I'm not kidding) I was a distributor so I know how the products work. If you have enough money to change your food to a shake and have the will to do what they say do it, but you can also save the money for a better plan of healthier food. Be free to ask me anything I can give you some pros and cons about the products, I used almost all products from herbalife but I lost more pounds quickly reducing my food portions than with herbalife.
