May 10, 2021
Having high blood pressure, high cholesterol and/or obesity from childhood through middle age were linked to poorer brain function by middle age. These cardiovascular risk factors were linked with low memory, learning, visual processing, attention span, and reaction and movement time. Strategies to prevent heart disease and stroke should begin in childhood to promote better brain health by middle age.

Exercise promotes healthy living and a healthy liver ... read more
April 12, 2021
Researchers have shown that an exercise regimen reduces liver steatosis and stiffness in patients with non-alcoholic fatty liver disease. These gains in hepatic health are mediated through modification of inter-organ cross-talk, circulatory organokine alterations and reductions in inflammation and oxidative stress. Because these benefits are unrelated to weight loss, all therapeutic regimens should integrate regular exercise and patients should remain diligent and compliant regardless of bodyweight changes.

Prehistoric Pacific Coast diets had salmon limits ... read more
April 12, 2021
Humans cannot live on protein alone - even for the ancient indigenous people of the Pacific Northwest whose diet was once thought to be almost all salmon. Anthropologists argue such a protein-heavy diet would be unsustainable and document the many dietary solutions ancient Pacific Coast people in North America likely employed to avoid 'salmon starvation,' a toxic and potentially fatal condition brought on by eating too much lean protein.

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.

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.

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.

Scientists have mapped out what happens to fat deposits during intermittent fasting (every second day), with an unexpected discovery that some types of fat are more resistant to weight loss.

Accelerating gains in abdominal fat during menopause tied to heart disease risk ... read more
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.

Deciphering the genetics behind eating disorders ... read more
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.

Researchers found that children with inconsistent sleep schedules have higher body mass index (BMI) percentiles. Her research also found that children from households with greater poverty had more overall inconsistent sleep onset times. But for families living in poverty, consistent bedtime scheduling may not be easily done, especially if a caregiver is the only parent, juggling multiple jobs, parenting multiple children or dealing with a tenuous housing situation.

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.
