Son inhaled thanksgiving dinner. is this normal?

Hi! This isn’t a subject I would normally be asking about, but google isn’t giving me answers. We had thanksgiving dinner last week, and my son (21M) ate half the table. I’m not exaggerating. I watched him gobble 2 turkey legs, 2 breasts, so much stuffing, 5 giant helpings of mashed potatoes, a shit-ton of green beans, and our entire helping of cranberry sauce. It was insane. His sister watched, jaw agape. I am not making this post to police his eating habits, but I’ve genuinely never seen this before. He told me it might’ve been a side effect of T, but he’s been on T for years and this has never happened before. Semi-worried about him, but let me know if there’s nothing to be worried about!

He said it was okay for me to post, because he was also kind of unsure.

EDIT: Thanks for all the replies! Found out what happened, though. Turns out he was stoned and completely forgot. What a man.
