If you’re dealing with a crabby co-worker or exasperating friend this season, maybe you should offer them some cake or cookies, because a new study has discovered that eating sweets make you sweet.

Researchers have done a study that suggests that people with a “sweet tooth” have sweeter dispositions. Psychologist Brian Meier says, "Taste is something we experience every day. Our research examined whether metaphors that link taste preferences with pro-social experiences (which is why we say, ‘she’s a sweetheart’) can be used to shed light on actual personality traits and behavior."

Why do some of us get fat, while others stay skinny? It turns out that there is "good" fat and "bad" fat, and some of us have inherited too much of the bad (brown) stuff, which is found throughout the interior spaces of humans and other warm-blooded creatures. It may hold the secret to diets and weight-loss programs of the future because, unlike ordinary "white" fat (where the body stores excess calories), brown fat can burn calories to heat up the body. It’s one of the things that helps keep us warm on cold nights.

We learn something new about obesity every day. We’ve learned that being fat starts in your brain, and now scientists say that appetite regulation has to do with the HAIRS in your brain. In other words, if you have fat brain hairs, you’ll have a fat body.

These tiny hairy projections, called cilia, are present on almost every cell of the body–including the brain. New research shows that the cilia on our appetite-regulating brain cells control whether our bodies get the "stop eating" signal in time for us to lay down our forks when we’ve had enough.

If you’re fat, it might be because of the way your mother ate when she was pregnant. A high-fat diet during pregnancy can lead to obese children. And mothers who were mistreated as children have an increased risk of giving birth to low birth weight babies.

This is often (but not always) part of growing up in poverty. Researcher said Amelia Gavin says, "Our findings suggest that a mother’s economic position in childhood and her experience of maltreatment during childhood have implications for her children born years later. To our knowledge, this is the first study to show that maternal childhood maltreatment may lead to lower birth weight among later-born offspring."
