Will weight redistribution after lipo happen with or without weight gain?

Dr Elizabeth Morgan answered one of my questions , her answer was a little bit concerning. She stated that if you stayed the same weight,fat appears in new areas, and if you lost weight after lipo you won't get fat distribution. I have read from other plastic surgeons on this forum that if you keep your weight the same you don't have to worry about fat distributing on other ares of your body. So who is right on this matter?
