a lot of it comes down to portion size and food choices. people used to eat more fruits and veggies and it wasn't normal to eat an entire bag of cheetos as a 'snack'
granted the poor dude in the right pic is an extreme, but yeah, food choices and portion size
I don't know if the dude on the right will ever be able to regain some semblance of a normal weight, prob would need a gastric surgery or something. what a horrible way to live
