Have you heard of Sensa? It’s the latest diet craze to sweep the nation. Alan Hirsch, MD, founder and neurologic director of the Smell and Taste Treatment and Research Foundation in Chicago, developed Sensa because he repeatedly saw patients gain considerable weight after losing their sense of smell and taste. Likewise, he found that when smell and taste are enhanced, people lose weight. It seems like those who smell and taste less should be less interested in food. Not so! Hirsch created a formula to sprinkle on food that enhances your sense of smell, and now urges us to sprinkle it on everything we eat.
