With 78 million American adults in the obese column and showing slim chances of permanently dieting their way out of it, one way of mitigating the public health disaster to come would be to unhook the wagonload of obesity-related ills -- most notably Type 2 diabetes and cardiovascular disease -- from obesity itself. In this scenario, a person could remain heavy, but take a medication or follow some regimen that drives down his or her risk of developing the metabolic dysfunction, the high blood pressure, worrisome cholesterol readings, fatty liver and inflammation that so often come with obesity.

Forget those long, grueling fasts you dreaded before getting blood drawn for a lipid test: A new study finds that it's probably OK to eat beforehand. Doctors assessing their patients' cardiovascular risk often send patients to get their lipid levels checked, with the caveat that they must fast for nine to 12 hours - which would mean they'd have to come back at a later time and possibly skip mealtimes to boot. This often leaves physicians in a bind because it's very possible the patients won't return.

Just as you were ready to tuck into a nice three-egg omelet again, comforted by the reassuring news that eggs are not so bad for you, here comes a study warning that for those over 40, the number of egg yolks consumed per week accelerates the thickening of arteries almost as severely as does cigarette smoking. Server, can you make that an egg-white omelet instead, please? The study, published Tuesday in the journal Atherosclerosis , measured the carotid wall thickness -- a key indicator of heart disease risk -- of 1,231 patients referred to a vascular prevention clinic, and asked each to detail a wide range of their health habits, from smoking and exercise to their consumption of egg yolks.

Potentially good news for the 45% of Americans who have Type O blood : researchers said Tuesday that those people appear to have a slightly lower risk of developing heart diseasethan their neighbors with Type A, B or AB blood. Dr. Lu Qi, an assistant professor of nutrition at the Harvard School of Public Health in Boston, analyzed heart disease risk in two large, multi-decade health studies - reviewing data collected from 62,073 women who participated in the Nurses' Health Study, which was launched in 1976, and from 27,428 men who took part in the Health Professionals Follow-up Study, launched in 1986. Adjusting for heart disease risk factors including diet, diabetes status, gender and race, Qi and his colleagues found that study participants with type AB blood had the largest heart disease risk - 20% greater than that of people with Type O blood.

American adolescents already carry a heavy burden of future heart disease risk, and while obesity has contributed mightily to their poorer health prospects, normal-weight kids are by no means off the hook, a study produced by the Centers for Disease Control says. In a study published Monday in the journal Pediatrics (read the full text here ), CDC researchers say that overweight and obesity among American adolescents -- those between 12 and 19 years old -- has pushed the prevalence of pre-diabetes and Type-2 diabetes from 9% in 1999 to 23% in 2008.

A new genetic study suggests that high-density lipoprotein, the so-called good cholesterol commonly known as HDL, may not actually be as good for us as physicians previously thought. A study of more than 100,000 people found that those with genes that promote production of higher-than-normal levels of HDL do not have a lower risk of having a heart attack, a finding that has surprised researchers immensely. The results could have major implications for pharmaceutical manufacturers, who have been attempting to develop drugs that will raise HDL in the hopes of preventing heart attacks in people at higher risk.
