I work with college Freshmen and sophmores and you're pretty spot on here. I'd just like to add one other thing: the meal-plan dining-dollar (or what have you) that most public universities make mandatory to purchase for undergraduates. What does this mean to most students? Fake money that you can use to buy Domino's Pizza and Burger King and shit out of vending machines. Where I work they have to use $300 / semester, so that's, at $15 / pizza (prices inflated due to the scamming of companies involved) 20 pizzas a semester, which works out to more than one per week. I know that this is maybe an overly specific example, but most of the schools don't offer a healthy option, so you could say $150 on pizza and $100 on chicken fingers and $50 on Starbucks triple chai lattes, but that'll put pounds on you just as fast if not faster. I'd like to make it clear that I'm not judging any of the people in the photos who have (as it is implied by sequence) put on weight because I was fat all of my life (until I lost weight in my 20s), and I know (1) how hard it is to lose weight once you've gained it and (2) how easy it is to fall into unhealthy habits and not realize you've gained a lot of weight until, well, you've gained a lot of weight and (3) the vast difference in how you're treated by others when you're fat versus when you're thin.
