Shit like this needs to be forced to gorge on a dose of reality.
For example:
People don't get fat because "food tastes too good", people get fat because of a sedentary lifestyle (which doesn't mean "lazy", working in an office is a sedentary lifestyle, but it's also very stressful), combined with the fact that eating releases all kinds of lovely endorphins, it's quite possible to get addicted to eating, especially when cheap food is either bland, fattening, or
both.
Not to mention, many people don't have the time or energy to cook (or learn how to cook) nowadays, so they eat out...
Not to mention, exercise takes
more energy which they don't necessarily
have...
It's a clusterfuck. Everything contributes to everything, and it creates a weird downward spiral that's nearly physically impossible to actually graph.
Honestly, "it's funny because he/she is fat" jokes need to die like the cruel abominations of humor that they are. If you're going to make fat jokes, actually do something entertaining, because posting an image of a fat woman and going "HAW HAW SHE'S FAT" is actually less intelligent than "Your Mom" jokes.
