DailyDirt: Counting Calories Should Be A National Pastime
from the urls-we-dig-up dept
While it may be a bit late for New Year's resolutions, it's never too late to start counting calories as part of a sensible weight loss (or maintenance) plan. But before embarking on a crusade to cut out all those extra calories, it might be wise to learn more about this unit of energy. For example, scientists are still debating whether all food calories are equivalent from a metabolic perspective -- are calories from fat the same as calories from carbohydrates? The answer still isn't clear, but one thing is for sure: eat fewer calories and you'll lose weight. Here are a few more interesting tidbits about calories.

- Bad news: Claims that sex burns 100 to 300 calories are just a myth, according to the New England Journal of Medicine. Apparently, one study found that sex lasted 6 minutes on average and burned only 21 calories. [url]
- Good news: Watching 90 minutes of a horror movie can reportedly burn almost 200 calories because it causes an increase in heart rate. For the greatest calorie-burning workout, watch The Shining. [url]
