Dr. Hirsch's Ground-Breaking Research Study

During his career, Dr. Hirsch observed that many patients who had lost their sense of smell due to head trauma frequently gained 20-30lbs. This prompted him to hypothesize that if losing one's sense of smell could lead to weight gain, could the opposite be true... could enhancing one's sense of smell lead to weight loss?

After painstaking research and testing, Hirsch created a blend of edible "Tastants" that he believed would enhance the smell and taste of food and eventually lead to weight-loss. He then tested those sprinkles in one of the largest research studies ever conducted on a non-prescription weight-loss product.

During his study, 1436 women and men sprinkled the scented, flavorless "Tastants" on everything they ate during a 6 month period and they lost an average of 30.5 pounds.

Those in the control group lost only 2 pounds, on average.

Now, Dr. Hirsch's breakthrough "Tastants" are available to everyone as SENSA® and hundreds of thousands of people have lost weight on the system.
