Talking About the Science of Smell

Dr. Alan Hirsch has appeared as a featured guest on dozens of national television programs.

As the founder and neurological director of the Smell & Taste Treatment and Research Foundation in Chicago, Dr. Hirsch specializes in the evaluation, diagnosis and treatment of many smell- and taste-related disorders.

For over 25 years, Dr. Hirsch has dedicated his medical career to helping people to overcome the loss of smell and taste sensations and once again enjoy fulfilling lives.

To date, Dr. Hirsch has conducted more than 180 studies on sensory phenomena and disorders. Many of these studies have explored how enhancing certain smells and tastes can impact eating patterns, mood, perception and even learning speed. In addition, Dr. Hirsch is currently conducting more than 80 studies on the effects of smell and taste on weight loss, sleep, consumer preferences and sexual habits, among many other topics.

His most remarkable studies have involved taste and weight loss. Unknown to most people is the fact that your senses of taste and smell have a profound effect on hunger and eating. This phenomenon is illustrated in the the following animated clip:


How Taste Helps You Eat Less

Based on this process, Dr. Hirsch began his groundbreaking research into smell, taste and hunger. Years ago, Dr. Hirsch noticed that those who lost their sense of smell gain between 10 to 20 pounds within just a few months.

Dr. Hirsch found that because these patients could not taste their food, their brains were not receiving the normal hunger-suppressing signals to keep them from overeating. Dr. Hirsch believed that he could...by enhancing taste sensations...help people with normal senses of taste to eat less, control food portions more effectively and lose weight more efficiently.


Sprinkles Enhance Weight Loss

After more than 10 years of testing different methods, Dr. Hirsch developed a formula consisting of specially processed tastant crystals. When sprinkled on food, these crystals affect the chemosensory receptors in the nose, mouth and brain to enhance taste, reduce appetite and increase feelings of fullness.

During a study with 92 overweight individuals, Dr. Hirsch found that those who used the tastant sprinkles lost an average of 33.6 pounds in only six months, without changing their normal diet or exercise routines.

He found that these sprinkles helped the study participants to:

  1. Eat less and feel full faster
  2. Stop eating earlier and enjoy every meal more

Now, this tastant crystal formula—called SprinkleThin—is being hailed as the easy, painless and sensible way to drop the pounds.

Dr. Hirsch is currently studying its effects on more than 3,000 overweight individuals, the results of which will be published soon.

Recently, Good Morning America profiled Donella, a dedicated user of Dr. Hirsch’s remarkable SprinkleThin formula. She says, “Sometimes I don’t even finish my entire meal! And it is not my choice, you know…you just sprinkle and start eating and I’m full [much faster].”
