Lipoic acid could reduce atherosclerosis, weight gain

A new study done with mice has discovered that supplements of lipoic acid can inhibit formation of arterial lesions, lower triglycerides, and reduce blood vessel inflammation and weight gain – all key issues for addressing cardiovascular disease.

Although the results cannot be directly extrapolated beyond the laboratory, researchers report that “they strongly suggest that lipoic acid supplementation may be useful as an inexpensive but effective intervention strategy . . . reducing known risk factors for the development of atherosclerosis and other inflammatory vascular diseases in humans.”

Drug that targets cannabinoid receptors cuts appetite, burns more energy

The first clinical studies of an experimental drug have revealed that obese people who take it for 12 weeks lose weight, even at very low doses. Short-term studies also suggest that the drug, called taranabant—the second drug designed to fight obesity by blocking cannabinoid receptors in the brain—causes people to consume fewer calories and burn more, researchers report in the January issue of Cell Metabolism, a publication of Cell Press. Cannabinoid receptors are responsible for the psychological effects of marijuana (Cannabis sativa), and natural “endocannabinoids” are important regulators of energy balance.

Appetite Regulation Molecule Found: Could Lead To Treatments For Obesity And Unwanted Weight Loss

A team of researchers from the St Vincent’s Campus in Sydney have developed a novel way to control the extreme weight loss, common in late stage cancer, which often speeds death. Continue reading “Appetite Regulation Molecule Found: Could Lead To Treatments For Obesity And Unwanted Weight Loss”

Researchers discover a gene that might control fat accumulation

Researchers at UT Southwestern Medical Center have found that a single gene might control whether or not individuals tend to pile on fat, a discovery that may point to new ways to fight obesity and diabetes.

“From worms to mammals, this gene controls fat formation,” said Dr. Jonathan Graff, associate professor of developmental biology and internal medicine at UT Southwestern and senior author of a study appearing in the Sept. 5 issue of Cell Metabolism. “It could explain why so many people struggle to lose weight and suggests an entirely new direction for developing medical treatments that address the current epidemic of diabetes and obesity.

“People who want to fit in their jeans might someday be able to overcome their genes.”

Surgery for severe obesity saves lives

An extensive swedish study from the Sahlgrenska Academy has established that surgery reduces premature death in patients with severe obesity. A long-term follow up has shown that mortality is significantly lower among patients who undergo surgery than among those who do not.

Scientists reveal how caloric restriction extends life by reducing toxic trash

Reduce, recycle and rebuild is as important to the most basic component of the human body, the cell, as it is to the environment. And a University of Florida study shows just how much the body benefits when it “goes green,” at least if you’re a rat: Cutting calories helps rodents live longer by boosting cells’ ability to recycle damaged parts so they can maintain efficient energy production.

“Caloric restriction is a way to extend life in animals. If you give them less food, the stress of this healthy habit actually makes them live longer,” said Christiaan Leeuwenburgh, chief of the division of biology of aging in UF’s Institute on Aging. Understanding how the process works at the cellular level in rodents could help scientists develop drugs that mimic the process in humans, Leeuwenburgh added.

Research identifies sirtuin protein instrumental in fat production and metabolism

A new Joslin Diabetes Center-led study has identified a protein found in fat cells that may play a major role in how fat is produced and stored, offering a new target for treatments to prevent obesity and reduce the risk for type 2 diabetes. This latest research appears in the August 2007 issue of Cell Metabolism.
