"Prolonged sitting is not what nature intended for us," says Dr. Camelia Davtyan, clinical professor of medicine and director of women's health at the UCLA Comprehensive Health Program. "The chair is out to kill us," says James Levine, an endocrinologist at the Mayo Graduate School of Medicine. Most of us have years of sitting experience, consider ourselves quite good at it and would swear that nature intended us to do it as much as possible. PHOTOS: 17 ways to fight the inertia, step by step But unfortunately, a good deal of data suggest that we're off our rockers to spend so much time on our rockers - as well as the vast variety of other seats where we're fond of parking our duffs.

Just a few nights of bad sleep is enough to throw the body's metabolism into disarray, according to a new study published Monday in the journal Annals of Internal Medicine. The study shows that getting four hours of sleep a night for four nights made healthy people's bodies resistant to insulin - a condition that is a common precursor of weight gain, diabetes and other serious health problems. In a healthy body, when you take in sugar, insulin is released from the pancreas and travels throughout the body, signaling to cells that they should absorb some of that new glucose.

Horace Albert Barker, 93, UC Berkeley biochemist, who made significant studies in the function of vitamin B-12. Internationally respected, Barker in 1944 helped pioneer the use of isotopic tracers to synthesize sugar, sharing the Sugar Research Award from the National Academy of Sciences. In the 1950s, he moved into vitamin B-12 coenzyme chemistry and later into bacterial metabolism, fatty acid oxidation and carbohydrate transformations.

Let's face it: No matter how many exercise books you read or classes you take, you probably still have fitness questions, and you're not alone. There's a dizzying array of health/fitness information to decipher. Furthermore, fitness isn't a one-size-fits-all proposition. Whether you're a mother-to-be, a desk jockey trying to stay fit or a senior with special needs, you need information to help you do the very best you can to lead a longer, healthier, more vigorous life.

Long after the buzz has gone, and even after the resulting hangover has cleared, a bout of binge drinking will leave your metabolism in a deeply disturbed state, which may be why binge drinkers -- even occasional ones -- are at greater risk of developing Type 2 diabetes (or its precursor, metabolic syndrome) than nondrinkers or those who drink more moderately. A new study, conducted on rats, suggests that binge drinking disrupts metabolism not by poisoning the liver but by inflaming the brain's hypothalamus, which conducts the symphony of signals necessary for proper metabolic function.

To take off extra inches, you don't necessarily need to start power walking, running, swimming or adding more time to existing cardio workouts. These are great calorie-burning options, but there is something else you can do -- a secret weapon in the fight against flab. It's strength training. Research has shown that adding just 3 pounds of muscle can increase resting metabolic rate by 7%. This means that with a little more muscle, your body burns more calories every day.

At least 4% of American youths age 12 to 19 -- and 30% of those who are overweight -- meet the criteria for metabolic syndrome, a condition that puts them at increased risk for diabetes and heart disease as adults.

Snoring and insomnia are conditions that appear to predict an individual's risk of developing metabolic syndrome and may even help cause it, according to a study released Wednesday. Metabolic syndrome is a constellation of risk factors -- excess abdominal fat, high triglycerides, high blood sugar, low HDL cholesterol and high blood pressure -- that increase the risk of diabetes, heart disease and stroke. University of Pittsburgh researchers examined 812 people age 45 to 74 for metabolic syndrome or diabetes and gave them questionnaires on sleep quality.

Harry Beevers, 80, a UC Santa Cruz biology professor who made breakthroughs in the understanding of the cellular structure of plants, died April 14 at his home in Carmel after a brief illness. A native of Durham, England, Beevers earned degrees in botany and plant physiology from Durham University. After postdoctoral study at Oxford, he immigrated to the U.S. and taught at Purdue University in West Lafayette, Ind., from 1950 until moving to UC Santa Cruz in 1969. He retired in 1990.
