Put the Liver to work!

For people that are way overweight, like 350 or more pounds, would the following procedure be possible? IAMNAD, so please forgive me my technical mistakes.

Could they hook up a person to a dialysis “like” machine and trick the liver into converting fat into glucose, and then clean the extra glucose out of the blood stream, until all the unwanted fat is gone?

Instead of liposuction where the fat is physically removed from the body, use the body’s existing mechanisms to convert the fat to glucose, and then remove the glucose from the blood?

This procedure would be used instead of other extreme procedures like gastric-bypass surgery where they clip off 90% of the stomach!

  1. Is it possible?
  2. How long would it take? a week, two weeks?
