Existing anti-obesity drugs may be effective against flu, hepatitis and HIV

September 28, 2008 - EurekAlert / Nature Biotechnology

Viruses dramatically increase cellular metabolism, and existing anti-obesity drugs may represent a new way to block these metabolic changes and inhibit viral infection

For insulin sensitive overweight patients, 1 session of exercise improves metabolic health

September 25, 2008 - EurekAlert / Integrative Biology of Exercise V Meeting

Exercise decreases everyone's insulin resistance and therefore reduces the chances of developing diseases such as type 2 diabetes. This study shows that even a single bout of exercise helps obese individuals increase their body's fat-burning rate and improve their metabolic health

Researchers note differences between people and animals on calorie restriction

September 24, 2008 - EurekAlert / Aging Cell

Calorie restriction, a diet that is low in calories and high in nutrition, may not be as effective at extending life in people as it is in rodents

Weight loss surgery may be associated with bone loss

September 23, 2008 - EurekAlert / Journal of Clinical Endocrinology and Metabolism

Weight loss surgery may be linked to deficiencies in calcium and vitamin D and bone loss

Peptide ghrelin may be involved in both alcohol dependence and overeating

September 23, 2008 - EurekAlert / Alcoholism: Clinical & Experimental Research

Ghrelin is a peptide found mostly in the stomach but also in the brain. Ghrelin is known to have an effect on food intake by increasing feelings of hunger and the urge to eat. New findings show that the ghrelin system may also be involved in addictive behaviors and brain reward

Healthy blood vessels may prevent fat growth

September 22, 2008 - EurekAlert / Stem Cells

Indiana University School of Medicine researchers report that the cells lining blood vessels may perform an unsuspected task -- controlling the development of fat cells

Calorie restriction does not appear to induce bone loss in overweight adults

September 22, 2008 - EurekAlert / Archives of Internal Medicine

Young adults who follow a diet that is low in calories but nutritionally sound for six months appear to lose weight and fat without significant bone loss

Surgery may help, but not cure, obese children with sleep disorders

September 21, 2008 - EurekAlert / 2008 AAO-HNSF Annual Meeting & OTO EXPO

Surgical interventions for many obese children suffering from obstructive sleep apnea may not cure the problem

Hormone discovery points to benefits of 'home grown' fat

September 18, 2008 - EurekAlert / Cell

A hormone found at higher levels when the body produces its own "home grown" fat comes with considerable metabolic benefits. The newly discovered signaling molecule is the first example of a lipid-based hormone as most are made up of proteins

Thin men more vulnerable to osteoporosis and bone fractures than other older men

September 18, 2008 - EurekAlert / American Journal of Epidemiology

Obesity and weight increase leads to an increased risk of many chronic diseases, and the advice is therefore to maintain a stable healthy weight. Now, research shows that there may be disadvantages to being thin. Men who have low weight in middle age and who reduce their weight, increase the chance of osteoporosis and fracture
