Chewing more makes you eat less

I understand the statement that if you had tougher food to eat that required more chewing, you would eat less. If something is more costly to eat, it simple to explain why you should eat less. It is no different than increasing the price of food. A brief discussion making this claim is here.

Chew More, Weigh Less?
Next time you grab a handful of nuts to snack on, count to 40.

A recent study revealed that when people ate a small serving of almonds, 40 chews quelled hunger better than 10 or even 25 crunches of the same amount of nuts.

The Magic Number
Not only did the extra chews help curb hunger best, but also the feelings of fullness lasted longest when people gave the nuts the extra chews. And the practice may work with other foods, too, because researchers suspect it may simply be the mere act of chewing that switches on your brain’s satiety center.
