Why do some people crave sweets and others don’t?

When the time comes, you have to move quickly: bring on the chocolate, the cookies, the gummy bears! Once you have a craving for sweets, no apple slices, no dates or raisins will help. The urge for sugar is so irresistible that it usually doesn’t stop at just one piece of chocolate or one cookie; often the whole package has to go for it.
