Diets will not help people with severe obesity in long-run

Body fat is controlled by more than 200 hormones. These hormones set a value for fat storage. Unhealthy diet, lack of exercise, irregular food habits, lack of sleep and stress trigger these hormones and reset the fat set point to a higher level.

If you want to lose weight, you need to work on these triggers. Diet restriction will not work in long-run. If you have mild obesity or mild diabetes, changing diet habits, doing regular exercise, regular food timings, adequate sleep and stress reduction will help to reset the fat value to a lower level. But if you are in severe obesity category or if you have severe diabetes, lifestyle modifications will not work. Even any time of diet including keto diet will not work in long-run as body got adopted to a higher weight level.

Liposuction is a cosmetic procedure. It is a very safe procedure for body shaping. But it is not for weight loss. Whatever weight you lose after liposuction will come back due to the effect of hormones controlling body weight.

Individuals suffering from sever obesity and severe diabetes will benefit from bariatric and metabolic surgeries. These surgeries induce long lasting weigh loss and control blood glucose in long term. Bariatric and metabolic surgeries are very safe and highly effective.
