In my holy/honest/humble opinion. A rephrasing of imo. Used in net-speak (read: retarded), it's mainly used to attempt to show that the opinion stated was either godly, true, or was stated by someone with humility. All three of those reasons are what would be simply known as bullshit. Retard1: omg imho, ur a fag lol.
As a cosmetic procedure, CoolSculpting is not covered by medical insurance. The out-of-pocket cost of CoolSculpting for fat cell reduction averages about $600 to $800 per treatment.
Answer Wiki. I'll only address one of the procedures you asked: CoolSculpting. It is safe in that it has been cleared by the FDA on September 2010. However, it is not a means to lose weight. As the name suggests, CoolSculpting is a body sculpting procedure meant to reduce about 20-25% of fat layers.
