ASAPS (American Society of Aesthetic Plastic Surgeons) and several other world authorities recommend fat removal equivalent to 5-8 percent of body weight as the upper limit. That means 5 kgs can be safely removed from a 60 kilos person and 8 kilos from a 100 kilos person. Liposuction of 500 ml or more fat is a major surgical procedure and is safe when done by a qualified person in a hospital with good anesthetic and ICU facilities. In absence of the above-mentioned, even smaller liposuction can be risky.
