Eat Brain Food
I hate to be a killjoy here, because I know that you've already had to say bye-bye to lots of pleasures in your life. But here's the thing: the more stressed and sleep-deprived you are, the more inclined you are to grab the chips and the cookies. Research has actually confirmed that: sleep deprivation and stress both contribute to obesity. It's a vicious cycle, because the more chips and cookies you consume, the more out of control your world spins.
Ideally, you want to shoot for lots of omega-3 fatty acids, vitamin B-12, and folate. Unfortunately, they're not hiding in a Hershey's dark chocolate bar. If I were God, I would change that. But you can find omega-3 fatty acids in boring but tasty things like salmon, tuna, sardines, walnuts, canola oil, and flaxseed. Vitamin B-12 is found in fish, seafood, meat, poultry, eggs, and dairy products. Folate is found in fortified cereals, spinach, broccoli, peanuts, and orange juice. Your brain will thank you.
