Be aware of liquid calories

Counting calories can be a drag, let's face it. Some people do it some of the time, while others never do it at all. I'll be the first to admit that it's a hassle. So, what do we do instead? We make educated guesses. A body of research has shown that we're wrong more times than we're right, so maybe this isn't the best approach, either. What, then, is the best way to go (providing we leave counting every calorie we consume out of the question)? Well, for starters, being at least reasonably aware of how many calories we're drinking.

That's what researchers from Perdue University suggest, pointing to the common practice of overindulging on liquid calories. More specifically, the researchers tested whether people who consumed many calories in drink form before a meal would take those calories into account when it came time to actually chow down. Turns out, the vast majority of people didn't.

Moreover, volunteers in the Perdue study reported feeling full -- whether they ate whole foods before their meal or had a drink. The major difference was that the group who had a drink (ex. watermelon juice instead of an actual piece of watermelon) consumed more total calories for the day.
