The Western World is fighting a losing battle against obesity, and it's no surprise: In a choice between exercise and bacon, the smart money in our culture is always on bacon. But it's not just because we're too greedy and lazy to lose our excess lard. There are a multitude of reasons for obesity, up to and including our own bodies actively conspiring against skinniness.
We're not saying that willpower and mental fortitude don't play a role. We're just saying that even if your mind is in the right place, the deck is still stacked against you in a bunch of different ways. For example ...
5Going on a Diet Has the Same Effects as Drug Withdrawal

Let's say you've found the motivation to lose that excess weight, no matter what. Following the diet advice you've heard your entire life, you quit the high-fat foods cold turkey and lay off the video games in favor of gym time. You're full of energy -- you're not going to let anything stop you from being the person you want to be, goddammit!
And then the withdrawal symptoms begin.
"Come on, man, just one of those vending machine bags of Cheetos to get me through the next few minutes."
How bad are they? Oh, nothing much -- just precisely like weaning yourself off a crippling drug habit.
According to research on mice (whose neurochemical system is comparable to that of humans), you don't even need to be morbidly obese to experience these symptoms -- all you need is to stuff your face with high-fat foods for six weeks or so. Then replace all that junk food with a carefully maintained, healthy diet and you get to live through all the joy and glory of a painful, mentally excruciating rehab period. The test subjects had significantly increased levels of stress hormones and abnormally high amounts of CREB, a protein linked closely to the dopamine reward system (aka the thing in your brain that gets you high). What other things can manipulate these brain levels? Just harmless little substances like cocaine and methamphetamine.
"Don't worry, it's just crushed-up Halloween candy."
And sure enough, the mice in the study became anxious and annoyed, avoided open spaces, and showed all the signs and symptoms of drug withdrawal just a few days after being deprived of their precious fatty foods.
Although this makes dieting infinitely harder than your average Weight Watchers ad makes it seem, it's not totally impossible. The trick here is to avoid yo-yo dieting, which sends you plummeting into an everlasting downward spiral of dopamined-up binge eating and withdrawal-laced, stressed-out dieting. If you want to quit heroin, you sure as fuck don't give yourself an occasional "cheat" day or week to treat yourself.
New Year's resolutions were meant to be broken.
