10. SNIFF A BANANA, AN APPLE, OR A PEPPERMINT WHEN YOU FEEL HUNGRY.

You might feel silly, but it works. When Alan R. Hirsch, M.D., neurological director of the Smell & Taste Treatment and Research Foundation in Chicago, tried this with 3,000 volunteers, he found that the more frequently people sniffed, the less hungry they were and the more weight they lost—an average of 30 pounds each. One theory is that sniffing the food tricks the brain into thinking you’re actually eating it.
