The new study was carried out by looking at two groups of women.

The first group featured 43 female college students who were between the ages of 18 and 22.

The second group featured 33 teens between the ages of 14 and 18.

For the study, they were then asked to drink either a chocolate milkshake, or a tasteless substance.

While drinking the substances, their brain activity was watched with an MRI brain scanner.

They discovered that the chocolate drink triggered activity in the dorsal striatum part of the brain.

In this area of the brain, there are many dopamine receptors.

Overall though, they found that obese people have fewer dopamine receptors, which led them to enjoying the drink less.

Since they did not get as much satisfaction from the drink, they had to consume more of it.

This could explain why obese people eat so much food, and pack on the pounds.

It is actually because they like food less than people of normal weight.
