I aggree, there are many people who want to lose weight by simply freezing off their weight and doing it cosmeticly. You must know that the weight will come back if you do not eat properly and exercise daily.
This is true, even if you do not freeze your fat and loose weight simply by diet and exersize.
I do agree in these percedures, if you are at the point where you simply feel you can't go on and loose weight on your own. These percedures are a good quick fix for those who are obease and need some extra weight lifted from their body so you can walk around a little easier.
