"Workout for 2.5 hours a day, plus 60-90 minutes transport on a bike, you can pretty much eat anything you like."

Trivial to debunk. Assuming 150 pounds. Weight lifting 2.5 hours: 1051 calories Cycling Moderate 1.5 hours: 1051 calories I'll generously add 2000 calories for the rest of the days activities.

Water intake daily 3.7 liters. 3.7 liters of soda: 1600 calories Burger and Fries: 1000 calories, 3 times a day: 3000 calories.

Calories burned daily total: 4102 calories Calories ingested daily: 4600 calories Yearly weight gain: 498*365/3500 = ~51 pounds.

You can flex the numbers a number of ways, but it's obvious that you cannot pretty much eat anything you like. Exercise does not make up for a bad diet.
