You think: If I see chocolate I eat it. There's no stopping me!
Why you can't resist: It's not just the taste that makes chocolate so tempting -- it's also the blissed-out feeling you get from eating it. When chocolate's potent blend of fat and sugar hits your bloodstream, it signals the reward center of your brain to release dopamine, a chemical that produces feelings of euphoria. The sensation is basically a mild version of the high that people get after consuming drugs or alcohol.
Take control by: Walking off the urge to indulge. Researchers at Britain's University of Exeter found that taking a 15-minute stroll may help curb chocolate cravings.
(or have a few squares of dark chocolate. it contains a lot more antioxidants than milk chocolate)
You think: After a bad night's sleep I have to eat constantly the next day. I'm ravenous!
Why you can't resist: Just a few nights of tossing and turning can send your appetite into overdrive.
That's because sleep helps regulate body weight and metabolism. (which is why it is so important to get good quality sleep whether you want to lose weight or not)
Log too few hours and levels of the hunger-regulating hormone leptin dip while the amount of ghrelin, a hormone that increases appetite, rises. And if you frequently miss out on sleep you may gain weight.
A joint Stanford University and University of Wisconsin study found that people who got less than eight hours of sleep a night had a higher body mass index than those who slept more.
Take control by: Getting enough rest. But since that isn't always doable, tweak your diet to fight that ravenous feeling, says Dr. Isaacs. Eating fruit, veggies, and high-fiber carbs regularly can help your body produce leptin more efficiently, while foods high in zinc, such as beef and low-fat dairy, may enhance leptin's effect.
