JMB1981, the very short answer is: Advocare will work for many, but not all. The way it is laid out, you must eat clean, good food and learn how to manange the portions and timing of food throughout the day. There are products you can add on to help with some of the issues, but you have to be willing and able to follow the directions to get the results. This program leaves a lot more of the success up to the individual because you pick the food. Day 11-24 does have a meal replacement shake for one meal; which is more for convienance than anything else. BTW, they ROCK, the flavors were developed my HaagenDazs, so it is really helpful in quieting a screaming sweet tooth. My overall: Great if you can follow directions and stick to it while having the ability to totally pick good, clean food.
