Does Florida prohibit plastic surgeons from removing a certain amount of fat during lipo? (Photo)

Yes - it is true.  the Florida Board of Medicine & Office Surgery Rules limit  the volume of liposuction that can be done.  When liposuction is done as a sole procedure, the limit is 4 liters of "floating fat" that can be removed.  Think of a 2 liter coke bottle, 2 of them, full of fat.  That is the limit.When you do other procedures, such as TT, the lipo limit drops down to only one liter.However, if your surgery is done in the hospital, more liposuction can be performed, as they are in a different category.

One of the most commonly held misconceptions is the myth of surgical weight loss via liposuction.
Liposuction is a sculpting tool. It is a targeted means of addressing subcutaneous fat excess. The best candidates are healthy individuals who have achieved a stable weight with stubborn or resistant target treatment areas.
Total body liposuction for volume reduction or debulking carries greater surgical risk. The loose skin which is likely to present post op often overshadows any benefit gained from volume reduction. While there are no limits for procedures performed in a hospital setting. For procedures performed in an office setting, the legal limit is FL is 4 liters.
In your case, I would recommend continued weight loss until you are within striking distance of your goal weight followed by an abdominoplasty (to address the aforementioned skin laxity).
As always, discuss your concerns with a board certified plastic surgeon (ABPS).
