Metabolic changes in fat tissue in obesity associated with adverse health effects ... read more
April 9, 2021
A twin study indicates that the machinery responsible for energy handling in fat tissue is working poorly in obesity. In the study, a clear reduction was seen in the activity of mitochondrial genes in obesity in fat tissue, while similar genome-level change in muscle mitochondria was minor. A link with adverse health effects was identified in the mitochondria of fat tissue only.

Health benefits of breastfeeding, for mother: Lactation and visceral, pericardial fat ... read more
April 9, 2021
As demonstrated by multiple studies, women who breastfeed have a lower risk for developing cardiovascular disease and diabetes, though the mechanisms by which these risks are reduced for lactating women are still not fully understood. Scientists recently completed a study to see if the presence of excess fat, specifically visceral and pericardial fat, could help explain this finding.

April 6, 2021
A new study in mice describes novel neurocircuitry between midbrain structures that control feeding behaviors that are under modulatory control by leptin, a hormone made by body fat. Since the discovery of leptin in the 1990s, researchers have wondered how leptin can suppress appetite.

Consumption of added sugar doubles fat production ... read more
March 16, 2021
Too much sugar is unhealthy - that we know, but it's not just down to the many calories. Even moderate amounts of added fructose and sucrose double the body's own fat production in the liver, researchers have shown. In the long term, this contributes to the development of diabetes or a fatty liver.

March 3, 2021
Women who experience an accelerated accumulation of abdominal fat during menopause are at greater risk of heart disease, even if their weight stays steady, according to a new analysis. The study -- based on a quarter century of data collected on hundreds of women -- indicates that measuring waist circumference during preventive health care appointments for midlife women could be a better early indicator of heart disease risk than weight or BMI.

March 1, 2021
By analysing the genome of tens of thousand people, a team has discovering similarities between the genetic bases of anorexia nervosa, bulimia nervosa or binge-eating disorder, and those of psychiatric disorders. Eating disorders differ in their genetic association with anthropometric traits. Thus, genetic predisposition to certain weight traits may be a distinctive feature of anorexia nervosa, bulimia nervosa or binge-eating disorder.

3D microscopy clarifies understanding of body's immune response to obesity ... read more
February 17, 2021
Researchers who focus on fat know that some adipose tissue is more prone to inflammation-related comorbidities than others, but the reasons why are not well understood. Thanks to a new analytical technique, scientists are getting a clearer view of the microenvironments found within adipose tissue associated with obesity. This advance may illuminate why some adipose tissues are more prone to inflammation - leading to diseases like type 2 diabetes, cancer and cardiovascular disorders - and help direct future drug therapies to treat obesity.

February 10, 2021
People who eat a Mediterranean-style diet -- particularly one rich in green leafy vegetables and low in meat -- are more likely to stay mentally sharp in later life, a study shows. Closely adhering to a Mediterranean diet was associated with higher scores on a range of memory and thinking tests among adults in their late 70s, the research found. The study found no link, however, between the Mediterranean-style diet and better brain health.
