Hi Kellieam1 -
The liquid diet is tough and he will def lose some weight, but I'm sure he will gain it right back when the bands come out.
Does he have an underbite/overbite/crossbite? Some cases that are more severe have tougher recoveries as they move the jaws forward or back more...
Best bet is to have a game plan while he is banded as far as liquid foods go. You can blend a lot of of stuff with water to get it liquidy enough to be able to get into the syringe and squirt into his mouth...
Being fit, I personally think def helps with the recovery....
My friends son has a bad underbite and he was also fit. He actually packed on about 10lbs prior to surgery knowning that he was going to lose it. He ended up losing far more than 10, but like I said, he gained it back no problem.
