Sure, you’ve been hearing diet tips like these from well-meaning people for years, but is there any truth to them? To set the record straight on the most oft-repeated advice, we consulted a team of nutrition experts. They revealed which strategies you should forget and which live up to their get-slim promise.
Q. Will chewing low-cal foods like sugar-free gum and celery help me burn calories?
A. It might, but hardly enough to trigger weight loss. Gum and certain veggies are often called “negative-calorie” foods because they supposedly take more energy for your body to chew or digest than they contain.
The negative-calorie myth was put to the test when researchers at the Mayo Clinic in Rochester, Minnesota, asked people to chew sugarless gum at a rate of 100 bites per minute. After calculating the energy expended (about 11 calories per hour), they concluded that a person who chomped on a piece every waking hour of the day for a month would lose less than a pound. As for celery? All that crunching does burn energy, but it amounts to less than the 6-calorie stalk contains. The bottom line: If you really want to shed pounds, give your jaw a rest and start moving your body.
