The term that you refer to is incorrect. The only healthy way to lose fat is to burn more fat and eat less. Liposuction with different techniques is to help the patient to lose the resistant area and not to shed pounds.
You must have your terms mixed up. Electrolysis is a method of using an electrical current to remove hair by destroying the follicle. Were you thinking of "lipolysis" which the the removal of fat from the body by either liposuction, ultrasound, laser, etc.?
