Most of what you will find for evaluation of any weight loss method is short term - that is did the subjects lose weight at the end of the program? In the better studies you will find the data up to about two to five years out and it is not encouraging. There is a problem though in looking at weight loss methods; it is similar to smoking cessation methods. Very few people use only one method to try to lose weight so you have to be able to sort out the methods and their effects.That is not that difficult on a short-term basis but it becomes more difficult as you go out the timeline. Also remember that liposuction is a surgical technique and has not effect on the behaviors that caused the weight in the first place. Some references:[I have only looked at the abstract] Grossman JA.
