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.

Mediterranean-style diet linked to better thinking skills in later life ... read more
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.

February 2, 2021
People who start adulthood with a body mass index (BMI) in the normal range and move later in life to being overweight - but never obese - tend to live the longest, a new study suggests. Adults in this category lived longer than even those whose BMI stayed in the normal range throughout their life. Those who started adulthood as obese and continued to add weight had the highest mortality rate.

Blood vessel cells implicated in chronic inflammation of obesity ... read more
December 31, 2020
When fat cells in the body are stuffed with excess fat, the surrounding tissue becomes inflamed. That chronic, low-level inflammation is one of the driving factors behind many of the diseases associated with obesity. Now, scientists have discovered a type of cell responsible, at least in mice, for triggering this inflammation in fat tissue. Their findings could eventually lead to new ways to treat obesity.

Maternal diet during lactation shapes functional abilities of milk bacteria ... read more
December 16, 2020
The mother's diet while breastfeeding can shape the profile of human milk oligosaccharides (HMO), a type of complex carbohydrate in the mother's milk. Changing the HMOs, which are food and fodder for healthy microbes, in turn modifies the functional abilities of the milk microbiome.

Lipid identified in human breast milk may play important role in early childhood weight ... read more
December 16, 2020
A lipid metabolite called 12,13-diHOME is in human breast milk. The authors of the study propose that 12,13-diHOME, as well as linked pathway metabolites from breast milk, have a protective effect against obesity development in offspring. They also suggest that a single bout of maternal exercise may boost levels of the metabolite in breast milk and that may translate into benefits for offspring in terms of healthy growth and development.

Kids gain weight when new convenience stores open nearby ... read more
December 10, 2020
A new study found that changes in the food environment around low-income and high-ethnic/racial minority populations over time impact childhood obesity. Increased availability of small grocery stores selling a selection of healthy items in close proximity to children's homes improves their weight status over time, whereas increased availability of convenience stores selling predominantly unhealthy foods is likely to be detrimental.

Obesity impairs immune cell function, accelerates tumor growth ... read more
December 9, 2020
A new study in mice finds that a high-fat diet allows cancer cells to outcompete immune cells for fuel, impairing immune function and accelerating tumor growth. Cancer cells do so by rewiring their metabolisms to increase fat consumption. Blocking this rewiring enhances anti-tumor immunity. The findings suggest new strategies to target cancer metabolism and improve immunotherapies.
