This is just so wrong. Pro athletes can get away with so much, because they exercise. An average sedentary person will not have the same allowances.
Most pro athletes get fat and sick once they retire, because old food habits stay.
I had a friend who was in a soccer team for the uni. He was a really good and dedicated athlete. He ate a bucket of KFC and 1.5L of Coke (sugar version) almost every day. He was shredded with six pack abs. Because he had 2x training sessions per day.
Needless to say, now he’s 30-something with a belly. Your average couch potato looking person.
