Scientists have uncovered a brain-stomach connection that may help explain why we crave food and keep eating even when we're full. Featured in the Journal Science, this study of hungry volunteers revealed specific brain activity linked to the anticipation that a good meal is on the way. When the stomach is full, that brain activity slows down, like a brake that helps a person avoid overeating. The study in the Journal Science says people with certain eating disorders may have a faulty brake system, and may not get the message to slow down when they are full. Researchers say the findings may help lead to a better understanding of eating disorders and could lead to behavior modification strategies to help re-train the brain's food craving center. The research was conducted at the Institute of Neurology in London and is published in the Journal Science, published by AAAS, the Science Society.
Kids are just as good as adults at least one thing, being couch potatoes. A government report released finds that kids are even less active than initially thought. That 60% of kids from ages 9 to 13 are not involved in sports outside of school. More than 20% aren't active at all during their free time. The Centers for Disease Control surveyed more than 3,500 kids to come up with these numbers and they say now parents have a big problem at home since inactivity is one of the contributing factors to the epidemic of childhood obesity, something that increases the risk of diabetes and other health troubles. Parents noted some reasons why they thought kids were not being physically active. They include: difficulties in transportation, lack of time and opportunities, expense, and concern about neighborhood safety.
If your living depends on tips from customers, you might take this tip from a study in the Netherlands. The researchers compared two groups of waitresses, one group repeated the customer's order and smiled and crouched down beside the patron. The other group was friendly too, but stood up the whole time and did not repeat the order. The crouching waitresses who repeated every order had nearly double the tips as the other group. So what does that mean? First, that tips reflect body language as well as service, and that those who appear to be good listeners, are better rewarded.
