If it was a scam, how far apart in time do you believe the “before and after” pics actually were?

They claimed he lost 7 pounds(3.17kg) of fat and didn't take steroids during the "experiment".
Then why is his face so gaunt in the before photo yet so bloated in the after. If he added 20.25 lbs (9.18 kg) of muscle and lost 7 pounds of fat, he would be ripped to shreds in the after pic.
What accounts for a bloated fatter-looking face in the after image where he had 7 LESS pounds of fat, and claims he wasn't taking drugs, which could bloat his face...
He doesn't look like he has 7 founds of fat to lose in the before. His face should look even gaunter in the after pics with 7 less pounds of fat. With less fat and more muscle, his bodyfat % would have gone way down in the second pic yet he doesn't appear to have any more definition. He's even flexing his quads in the second one, tightening up his abs, and sticking his lats out, and has more contrasting lighting which would highlight definition better.
