Instead, pack some healthy, high-protein snacks (like nuts, or some jerky if you're into that) to keep on hand for those times your stomach wants to override all reason.
I'm [anxious, sad, rejected, bored, lonely], so I might as well hit the drive-thru
You know what humans hate? Feeling uncomfortable. You know what life makes you do? Feel uncomfortable. You're inevitably going to experience negative emotions, and there's a good chance you'll try to suppress them using food, at least some of the time. Start dealing with that painful stuff -- i.e., don't believe burying it is the best option -- and you'll be less likely to hit the drive-thru every time you have a shitty day at work.
Drinks, then PIZZA
Drunk you is a saboteur. Do as little damage as possible.
I need to look like a model to have a beach body
You know what's a whole hell of a lot easier than sacrificing food and happiness for your (likely unattainable) dream body? Changing your expectations. Sure, maybe you could stand to lose some weight so you have a better chance of living to see your future kid graduate, but if you're gunning for a ripped, perfect body at the cost of sleep, fun, dating, and bread, ask yourself if it's really worth it. You're probably far more likable, and happier, a little softer than you want to be. Adjust your expectations to something a little more achievable (and sustainable), and wham! You've instantly hit your goal.
