Okay to Lose Weight After Lower Body Lift?

Thank you for your question.  Congratulations on your weight loss.

You should be at your baseline / stable weight prior to having surgery (or as close to it as possible).  During the recovery process, you may have some weight gain/loss and that does not affect the results (usually not more than 10 pounds), but if you lose a significant amount of weight after any type of surgery then it will affect the results.  After the tummy tuck surgery, if a patient loses 15 pounds or more, they will notice loose skin.

The recovery process is very important (and a bit difficult) but as long as you have realistic expectations and someone to help you through the recovery, you should be fine.

Best Wishes

Congratulations on your weight loss.  There should be no problem with having a body lift with a BMI of 23.  Ideally, I ask my patients to reach a stable body  for about 4 to 6 months.  Also I recommend that you settle on a reasonable body weight.  If losing 10 to 20 pounds more is difficult, then you shouldn't even try .  That is, it will not make a significant difference in your overall cosmetic results.
