Why I Can Eat a Bag of Pretzels

Because they don't smell!!!

The study, carried out by the Institute Food and Nutrition in The Netherlands, saw participants serving themselves custard out of squeezy tubes, while different concentrations of custard aroma were wafted past their nostrils. When a stronger smell was used, the amount of custard the participants ate decreased. The result appears in the wonderfully titled journal Flavor. 

So, I will now start working on my best-selling diet book,  "The Bacon, Cheese, and Onion Diet." I will make millions!
