Hot Dog!

1 Could Fat Dogs Curb the Obesity Epidemic?

Fat dogs have lower body temperatures than lean dogs which may cause weight gain, says research from USC. Dr. Roberto Refinetti compared body temperatures of 287 lean and obese dogs over several years and found that when comparing dogs of a similar size - say, a Havanese and a Bichon - obese dogs have lower temperatures than lean ones. Most humans gain weight when more energy, i.e., food, is consumed than is expended. Refinetti postulates that since warm blooded animals spend much of their energy keeping warm, those with naturally lower temps don’t need to use as much energy to stay warm. "Although not yet replicated in humans, these results suggest that human obesity may be caused by a small reduction in the temperature at which the body maintains itself," he said.

Buttering You Up

2 Iowa Fair Features Fried Butter on a Stick

The Iowa State Fair, taking place at the same time as the nearby 2011 Ames Straw Poll for Republican presidential hopefuls, is home to 50 foods that come "on a stick," including fried butter. Also featured at the Iowa fair is a hot beef sundae, reports CBS News. The large state fair, showcasing a famous "butter cow" sculpture, is held in Des Moines. MSNBC reports that non-presidential candidate Sarah Palin has said she's excited to try some fried butter on a stick "in honor of those who'd rather make us eat our peas," a jab at Michelle Obama's campaign to end childhood obesity. Fried butter on a stick or not, it's clear there's plenty of buttering up to go around in Iowa this weekend.

3 Vitamin D Linked to Age of First Menstruation

A study conducted by the University of Michigan School of Public Health found that Colombian girls 5 to 12 years old with low vitamin D levels doubled their chance of having their first period, called menarche, during the 30 month follow up. Fifty-seven percent of deficient girls reached menarche around 11.8 years compared to 12.6 years in the sufficient group. Only 23 percent of girls with normal vitamin D had their first period during the study. Early menstruation is linked to behavioral and social problems in teenagers and increases the risk of developing cardiometabolic diseases and breast cancer in adulthood. Previous research has shown that girls closer to the Equator reach menarche later than girls in northern regions where vitamin D deficiency is common in the winter.
