What you think about competitive eaters? And YouTuber food porn eaters??
Eriktheelektrik comes to mind.
He routinely eats +10000 kcal junk food.
Even if he vomits or eats half of what he claims with camera tricks, wouldn't it catch up and fries their pancreas, and if they vomit regularly it can't be good for their throat and esophagus.
Obviously these guys aren't the most smart and emotionally balanced people out there, but still it is amazing how they ignore not so long term health risks.
