Heart transplants from severely obese donors show comparable outcomes for patients

Heart transplant patients who received hearts from severely obese donors had similar short-term outcomes and long-term survival as patients who received hearts from non-obese donors, according to new research published today in Circulation: Heart Failure, an American Heart Association journal. The waiting list for a heart transplant in the U.S. is continuously about 3,000 people, and only half of those […]

How interval training affects ‘belly fat’ in obese 70-year-olds

By today’s estimates, one-third of adults aged 65 or older are obese. This growing obesity trend, along with the decrease in our level of physical activity as we age, seriously raises our risk of diseases and death. We know that aging leads to a gradual decrease in lean body mass (LBM). Put simply, LBM is the entire weight of your […]

In what is believed to be the first study to use an objective measurement of circadian rhythm—salivary melatonin—to examine associations of sleep health with insulin sensitivity in adolescents, researchers found that shorter sleep duration, later weekday bedtimes and […]

Obese mice lose a third of their fat using a natural protein

To the great surprise of cancer researchers, a protein they investigated for its possible role in cancer turned out to be a powerful regulator of metabolism. The Georgetown University-led study found that forced expression of this protein in a laboratory strain of obese mice showed a remarkable reduction of their fat mass despite a genetic predisposition to eat all the […]
