Obesity :: Body-weight regulation scientists give perspective on obesity-related research

When obesity overloads the body with excess nutrients, parts start to fail. Obesity contributes to heart disease, stroke, diabetes, high blood pressure, some cancers, liver disease, immune dysfunction, painful joints, and a host of other problems. With so many parts of the body affected, studies of the health effects of obesity that concentrate on one body organ or system may overlook common underlying events occurring at the cellular level throughout the body.

Obesity :: Fighting obesity may be as easy as ATP, says UH researcher

Wearing a portable instrument to monitor metabolism in the fight against obesity and its related health consequences may be on the horizon thanks to collaborative research being performed at the University of Houston and The Methodist Hospital.

Diet :: Severely restricted diet linked to physical fitness into old age

Severely restricting calories leads to a longer life, scientists have proved. New research now has shown for the first time that such a diet also can maintain physical fitness into advanced age, slowing the seemingly inevitable progression to physical disability and loss of independence.

Cholesterol :: MIT links gene to cholesterol

MIT researchers have discovered a link between a gene believed to promote long lifespan and a pathway that flushes cholesterol from the body. The finding could help researchers create drugs that lower the risk of diseases associated with high cholesterol, including atherosclerosis (clogged arteries) and Alzheimer’s disease.

Healthy :: Healthy restaurants help make us fat

If you’re like most, you eat worst at healthy restaurants. The “health halos” of healthy restaurants often prompt consumers to treat themselves to higher-calorie side dishes, drinks or desserts than when they eat at fast-food restaurants that make no health claims, according to a series of new Cornell studies.

Newborn :: Gene-chip studies provide new leads in treating lung disease of premature newborns

Some 20 to 40 percent of extremely premature infants suffer abnormal lung development leading to bronchopulmonary dysplasia, a chronic lung disease that can cause long-term breathing problems. Little is known about how to predict whether a premature infant will develop BPD in the weeks after birth, much less how to prevent or treat it. Now, gene-chip studies of these tiny babies’ umbilical cords provide unexpected, much-needed leads into predicting and treating this debilitating condition.

Weight Loss :: GSK applies for licence to market OTC weight loss product In Europe

GlaxoSmithKline (GSK) announced its marketing application for non-prescription orlistat 60mg for weight loss has been accepted for review by the European Agency for the Evaluation of Medicinal Products (EMEA).

Aging :: Sirtris & Harvard discover new mechanism to slow aging

Sirtris Pharmaceuticals, Inc. (NASDAQ: SIRT), a biopharmaceutical company focused on discovering and developing small molecule drugs to treat diseases of aging, announced publication of a study by Sirtris and Harvard University scientists in the journal Cell that reveals a new mechanism to slow aging.

Insulin :: Sugary drinks, not fruit juice, may be linked to insulin

Steady increases in consumption of sugar-sweetened beverages over the last several decades, as well as rates of Type 2 diabetes mellitus, led nutritional epidemiologists at the Jean Mayer USDA Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University and colleagues to explore the relationship between sugar-sweetened beverage consumption and insulin resistance, a precursor to Type 2 diabetes.

Obesity :: GI concept tested in children

Experts are struggling to find ways to contain the growing number of children who are becoming obese. One useful approach might be to encourage them to choose low glycaemic index (GI) foods. However, until now there has been little evidence that this approach will work for children in the long term.
