The skinny on fat
Fat in the liver -- not the belly -- is a better marker for disease risk
Aug. 24,
2009 -- New findings from nutrition researchers at the School of Medicine suggest that it's not whether body fat is stored in the belly that affects metabolic risk factors for diabetes, high blood triglycerides and cardiovascular disease, but whether it collects in the liver. They report online in the journal PNAS Early Edition that when fat collects in the liver, people experience serious metabolic problems such as insulin resistance, which affects the body's ability to metabolize sugar.

Liver fat key to diabetes, heart disease
Apple or pear shape is not main culprit to heart woes — it's liver fat
Dec. 3,
2008 -- Pear-shaped people who carry weight in the thighs and backside have been told for years they are at lower risk for high blood pressure and heart disease than apple-shaped people who carry fat in the abdomen. But in two studies, School of Medicine researchers report that body shape isn't the only marker of risk. Excess liver fat appears to be the key to insulin resistance, cholesterol abnormalities and other problems that contribute to diabetes and cardiovascular disease.

Calorie restriction diets may benefit rodents more than humans
Researchers note differences between people and animals on calorie restriction
Sept. 24,
2008 -- Calorie restriction, a diet that is low in calories and high in nutrition, may not be as effective at extending life in people as it is in rodents, according to scientists at the School of Medicine. Previous research had shown that laboratory animals given 30 percent to 50 percent less food can live up to 50 percent longer, but new research suggests the diet may not have the desired effect unless people on calorie restriction also pay attention to their protein intake.

Fighting childhood obesity with fruits and vegetables
Parents shape whether their children learn to eat fruits and vegetables
Aug. 7,
2008 --
Providing fruits for snacks and serving vegetables at dinner can shape a preschooler's eating patterns for his or her lifetime. To combat the increasing problem of childhood obesity, researchers are studying how to get preschoolers to eat more fruits and vegetables. According to researchers at Washington University in St. Louis, one way is early home interventions — teaching parents how to create an environment where children reach for a banana instead of potato chips.

Staying strong
Older women, not men, have a hard time maintaining muscle mass
March 25,
2008 -- Women over age 65 have a harder time preserving muscle than men of the same age, which probably affects their ability to stay strong and fit, according to research conducted at the School of Medicine and the University of Nottingham in the United Kingdom. For the first time, scientists have shown it is more difficult for older women to replace muscle that is lost naturally because of key differences in the way their bodies process food.
