Sensa is a diet product developed by neurologist Dr. David Hirsch, the director of the Smell & Taste Treatment and Research Foundation in Chicago. Sensa is a fine powder created to be sprinkled over food to help facilitate a feeling of fullness by using your sense of smell. The Sensa sprinkles, called "tastants," come in small boxes that are divided into two compartments, one for salty foods and one for sweets.
Tastants
Sensa's official website, TrySensa.com, reports that Dr. Hirsch developed the tastant crystals based on years of researching the science of smell and taste. The tastants have a very slight odor and flavor but do not alter the taste of foods when sprinkled on in the recommended amount. The ingredients in tastants are maltodrexin, which is derived from corn, tricalcium phosphate, carmine, soy and milk. Dr. Hirsch claims that the tastants act on your sense of smell to trigger the satiety mechanism in the brain sooner, causing you to eat less.
Clinical Trials
According to TrySensa.com, 1,436 people sprinkled tastants on everything they ate for six months. Study participants did not change their current diet or exercise program. They lost an average of 30.5 pounds, with a control group losing only two pounds. The site reports that this trial was followed by a placebo-controlled, double-blind study conducted by an independent laboratory, though the laboratory is not named. In this study, participants using Sensa lost an average of 27.5 pounds.Those in the control group gained an average of 1/2 of a pound.
Sensa Support
With an active online community accessed via TrySensa.com and a Facebook page closely monitored by Sensa representatives, the program offers significant support to dieters. Phone support is also available for those who have questions. The website features weight loss success stories with photos to provide motivation. It also offers extensive diet and exercise suggestions.
Outside Reviews
There is some skepticism on the part of diet experts as to whether Sensa actually works. Mayo Clinic nutritionist Katherine Zeratsky points out that the studies indicating Sensa's effectiveness do not indicate whether the participants who lost weight kept it off, and suggests sticking with the known formula of eating less calories than you burn in order to achieve lasting weight loss. Pamela Peeke, clinical professor of medicine at the University of Maryland states that there is no adequate scientific proof that Sensa works.
