PHILADELPHIA (CBS) – Do you have great willpower when it comes to food?

Did you ever wonder what makes some of us better than others at saying ‘no’ to fatty foods? Some of the best research in the country is being done at Yale and researchers there have found some of us are better chemically wired to refuse high-calorie foods, while others succumb to the temptation.

Their study monitored blood sugar levels in both an obese group and a non-obese group as they were shown pictures of high and low calorie food. When the sugar levels dropped, participants in either group were more likely to crave the high-calorie food. Those who craved high-calorie foods more often tended to be those in the obese group. It is not surprising but it shows the cause and effect relationship.
