Hello,
I hope the bariatician has explained you the that liposuction is used as a life saving technique and it is not to be used as a cosmetic surgery.
Weight loss post liposuction depends on diet threshold, the level of surgery done, metabolic issues etc.
I would suggest if you do not suffer from any health ailments, go for natural weight loss as that is quite prudent.
Next Steps
Consult a bariatician (if liposuction is mandatory)
