Weight Loss Through Liposuction Better Than Dieting?

Absolutely not. Liposuction is not weight reduction and those whose choose this route will be disappointed. It is not too uncommon for me to turn patients away for liposuction because their intentions and expectations will not be met because there are looking for a weight loss program.
Areas that are liposuctioned can still and will gain weight and fat if weight gain occurs after the surgery. It is a lifestyle change that is needed not liposuction. Most patients that are happy after liposuction are those that are at their or close to their ideal body weight who undergo the procedure.
Good luck.

Liposuction should not be used to lose weight.
On average, we typically remove 2-4 pounds of fat.
Aggressive liposuction is commonly limited to 11 pounds.
Rarely is more than this removed and, if done so, is typically  performed  where aftercare can be monitored.
