The Role of Specific Olfactory Stimulation in Appetite Suppression and Weight Loss

New insights into the mechanism of hunger and satiety provide a new approach to an old problem of weight regulation. It is known that the sense of olfaction via this olfactory-satiety feedback loop has a powerful and immediate effect on appetite regulation. The goals of this present study were to test the association of the inhalation of the specially formulated hedonic scents and weight reduction in a double blind, randomized, controlled study. This study tests the hypothesis that inhalation of specially formulated, positive-hedonic scents can function in the acute regulation of appetite and contribute to satiety. We also test the hypothesis that the inhalation of positive hedonic scents can lead to sustained weight loss. Our study conclusively proves in a randomized, controlled, double-blind fashion that the inhalation of specially formulated scents are effective in appetite reduction, squelching food cravings and weight loss without any conscious dieting or exercising.
