It is supposedly some sort of magic stuff that you shake on your food and it helps you lose weight. We shall see. I bought it online with a free 30 day trial to see what I think. I am starting tomorrow because I really need to go out and buy some normal food to eat during the day. I dont have food that I make for breakfast or lunch really. I am gonna get some stuff like tuna salad and fruit cups. It says to eat as you normally would but just sprinkle this stuff on your normal food. If you are a little overweight or even a lot overweight like me...look it up online like I did. Sensa. If it works at all I am going to attempt to stay on it for awhile. There are people on the support website which is like this one that have a lot of weight like I do who are losing over 100 pounds.
