Can chewing gum help a person lose weight?
Q: Can chewing gum help you lose weight?
A: It may help some people lose weight, but don't count on it as an important strategy. There are several theories why chewing gum may support weight loss, but research doesn't show strong results.
One often-quoted study found that chewing gum may burn about 11 calories an hour. This could be compared to the small extra daily calorie burn found in people who tap their toes or otherwise "fidget" all day, and it is unlikely to produce weight loss. Others propose that the act of chewing may lead to changes in digestive hormones that decrease hunger, thus making it easier to cut calories for weight loss. This makes sense in theory, but short-term controlled trials haven't shown the expected hormonal change.
Chewing gum may aid weight loss by replacing overeating for some. Participants in one controlled study showed a 10 percent drop in midafternoon snacking when they chewed gum 15 minutes each hour after lunch. But, in a controlled trial that followed overweight people for eight weeks, those who chewed gum 90 minutes a day did not lose weight any more successfully than those who didn't chew gum.
Consider other strategies to avoid extra eating. Brushing your teeth immediately after a meal helps some people. Try the tradition followed in India of ending meals by chewing a few fennel seeds, or just enjoy a nice cup of tea or coffee. If you find that chewing gum helps, that's great, but think of it as just one small part of changing eating habits to support weight loss.
