A few new studies reveal startling info about how you might be getting in your own way when it comes to managing your weight. Here's the 411, plus what to do about it...

Drinking coffee and diet soda has been linked to increased calorie intake. This study found that drinking coffee resulted in more overall daily calories, and consuming diet drinks was associated with eating calorie-dense, low-nutrient foods. If you're actively cutting calories in your drinks, don't mess things up and just add 'em back, especially not in the form of bad-for-you food. Prioritize healthy snacking (click for some of our favorites) and keep an eye on your overall calorie intake.

On-the-go eating could trigger overeating... even more than sitting around watching TV. According to this small but intriguing study, subjects who ate a cereal bar while walking went on to consume more calories that day than those who ate the bar while talking to someone or watching TV. Bottom line? Snacking on the move can impact more than your food choices at the time... it can affect your decisions all day. So grab a seat, focus on what you're eating, and then go about your day!

Believing you're naturally thin or fat can compromise your overall health. Be it genetics or something else, many people are stuck in the mindset that their weight is more or less out of their control. This new study shows that this thinking often leads to unhealthy food choices, lack of exercise, and poor physical health. Always been thin, but living on Doritos and Coca-Cola? Not good for you in the long run. Overweight all your life, so figure you shouldn't even exercise? Even if you don't lose weight, it's still smart behavior that will benefit your health.
