LOL this is funny.
I was on the wrestling team at Clemson in the late 80's and early 90's. they were a legit, Div 1, top 20 program. We shared dorms with other athletes, including the swim team.
God, we hated those fuckers.
When the swim team hit their peak training, they were actually made to go to the cafeteria at 10:30 pm and forced to gorge. Fried Chicken, Ice Cream, Stuffing, just about any calorie dense item you could think of. They were burning north of 7000 calories a day in the water. And though they certainly ate plenty of healthy food, it was very difficult for them to get all the calories they needed without throwing in some items you might consider junk food or not healthy food.
That is why swimmers get so fat after they stop swimming just like wrestlers get fat when they stop wrestling. They still eat like they are training.
