If excess weight builds up in the throat, it will narrow your airway, causing you to snore. Studies about habitual snoring have revealed that the typical snorer is male and overweight. Obviously, being overweight is the easier thing to change. While losing weight won’t cure snoring, according to Clete Kushida, M.D., director of the Stanford Sleep Medicine Center in Redwood, Calif., it can lessen the volume and frequency of your snoring. Plus, losing weight is good for general health. You may have to lose 10 percent of your body weight before noticing a difference in your snoring, says Nina Kolstanginova, M.D., of the Hamden Sleep Disorder Center of Connecticut.
