i am on jenny right now and it does work, the only thing that i hate is i get tired of the food after awhile.. but it does work they need to get more food choices on there menu expand it if you will ..i was on it before and lost 25 pounds but when i came off i gained it back because i didn't learn how to maintain, so i came back and hopeing that i can stick thorough to the end if i don't get tired of the food again lol.. with any weight loss program you have to be deicaded and serious about it .
