Best surgery for extracting large amount of fat?

I am aware that diet and exercise are the best way to lose weight and those healthy habits can help ensure weight loss is long term. However, if a person is wanting to bypass the TIME it would take for that and wants to go down 3, maybe 4 dress sizes, (approxumately 60 lbs) what would be the best surgical procedure(s) and what would be the average cost?
