Can I get liposuction or noninvasive surgery to jump start my diet?

You are half way there if you really WANT to get control of your body.  It is the desire for a better quality of life that fosters adherence to any treatment plan. In my opinion, the first step, beyond the commitment to yourself you may have already made, is for a trained professional to learn more about you.  Dietary history, lifestyle assessment, understanding of what you can and cannot do, and other factors must be considered in formulating a plan that will succeed.  Your hormone levels may be contributing, and if they haven't been checked, perhaps they should be.  Your path to this circumstance should be analyzed, and weaknesses discussed.  It's all about the result.  A powerful plan is then formulated, and a pact entered, that there is no going back.  you are the only one who can do this for yourself, but get good help for the journey.

It's a good question. It's unlikely that liposuction would do anything to jumpstart your weight loss. Liposuction is a sculpting procedure, and not meant for any significant weight loss. I would consider getting plugged into a weight loss clinic, or weight loss surgery. This includes banding and gastric bypass procedures.
