New research on the brain suggested that women unconsciously have a tougher time resisting their favorite foods than men do and the researchers speculate that it is due to the fact that they have to eat for two at some point of their lives.

They believe that it could be evolution that leads them to this because of their important mission to have a baby.

The goal of the latest study was to determine why some people don't stop eating when they're full. Our body tells us that we've eaten enough by sending a signal to our brain from the gut, however, the message usually reaches a bit too late if we eat fast, usually when we have already overeaten.

This is probably why some people when approached to the buffet, sometimes just cannot stop.

For the study, the researchers asked 13 women and 10 men about their favorite foods. A variety of dishes and desserts, including lasagna, pizza, brownies, ice cream and fried chicken have been reported. Then, after they fasted for 20 hours, the researchers presented them with their favorite foods. The study participants were allowed to smell and taste the food but not eat it. Then, in an experiment, they were told to try to inhibit their desire to eat the food.

Meanwhile, PET scans examined their brain activity.

The researchers found that certain areas of the brain became more active in both the men and women when they were tempted with food. The brain areas that lit up control emotions such as motivation. Also, both men and women succeeded in making themselves feel less hungry by inhibiting their desire to eat the food. But the brain scans suggested that the women's brains were still acting as if they were hungry.

In other words, the women may have thought they were less hungry, however their brains didn't seem to be accepting this fact.

The researchers believe it could be the hormones that play a factor in women because they need to eat more when they're pregnant.
As for those people who can't resist or inhibit themselves for certain kinds of high-calorie food, they certainly need help which will be the researchers’ next goal.
