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.

An avocado a day keeps your gut microbes happy, study shows ... read more
December 15, 2020
Eating avocado as part of your daily diet can help improve gut health, a new study shows. Avocados are a healthy food that is high in dietary fiber and monounsaturated fat. However, it was not clear how avocados impact the microbes in the gastrointestinal system or 'gut.'

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.

November 18, 2020
The results of a new study suggest that high-protein total diet replacements are a promising nutritional strategy to combat rising rates of obesity.

Gene in mice controls food cravings, desire to exercise ... read more
November 5, 2020
National Institutes of Health researchers have discovered a gene in mice that controls the craving for fatty and sugary foods and the desire to exercise. The gene, Prkar2a, is highly expressed in the habenula, a tiny brain region involved in responses to pain, stress, anxiety, sleep and reward. The findings could inform future research to prevent obesity and its accompanying risks for cardiovascular disease and diabetes.

November 4, 2020
Problems with the sense of smell appear to be an early indicator of cognitive decline in people with type 2 diabetes. However, it's unknown whether factors such as diet and obesity play a role in who develops these symptoms. Now, researchers have found that mice fed a moderate-fat, high-sugar chow (simulating a Western diet) showed a faster decline in their ability to learn and remember new odors.

October 26, 2020
Adults with severe obesity (BMI greater than 35) and a prior heart attack who undergo weight-reduction surgery may lower their risk of a second heart attack, major cardiovascular event, heart failure and death. The effect weight-reduction surgery had on the patients' weight, blood pressure, cholesterol and A1C (a Type 2 diabetes marker) seems to play a role in decreasing the risk of heart attack and death.

Obesity and disease tied to dramatic dietary changes ... read more
October 21, 2020
The 'mismatch hypothesis' argues that our bodies evolved to digest the foods that our ancestors ate, and that human bodies will struggle and largely fail to metabolize a radically new set of foods. This intuitive idea is hard to test directly, but the Turkana, a pastoralist population in remote Kenya, present a natural experiment: genetically homogenous populations whose diets stretch across a lifestyle gradient from relatively 'matched' to extremely 'mismatched' with their recent evolutionary history.

Vitamin A boosts fat burning in cold conditions ... read more
October 21, 2020
A recent study shows that cold ambient temperatures increase vitamin A levels in humans and mice. This helps convert 'bad' white adipose tissue into 'good' brown adipose tissue which stimulates fat burning and heat generation.

Genetic risk of developing obesity is driven by variants that affect the brain ... read more
September 29, 2020
Some people are at higher risk of developing obesity because they possess genetic variants that affect how the brain processes sensory information and regulates feeding and behavior. The findings support a growing body of evidence that obesity is a disease whose roots are in the brain.

Time-restricted feeding improves health without altering the body's core clock ... read more
September 17, 2020
For the first time, scientists have studied the early effects of time-restricted feeding on the daily periodic oscillations of metabolites and genes in muscle, and metabolites in blood. The findings find that time-restricted feeding does not influence the muscle's core clock, and opens the door to more research on how these observed changes improve health.

A ferry protein in the pancreas protects it from the stress induced by a high-fat diet ... read more
September 16, 2020
Scientists have now uncovered a key mechanism by which pancreatic function is maintained in response to a high-fat diet. A protein present in pancreatic insulin-producing cells protects them from damage under the stress induced by a high-fat diet. As the world increases its intake of high-fat foods and as type 2 diabetes incidence rises as a result, this protein could be a novel therapeutic target for type 2 diabetes mellitus.

Factors inherent to obesity could increase vulnerability to COVID-19 ... read more
September 16, 2020
Conditions related to obesity, including inflammation and leaky gut, leave the lungs of obese patients more susceptible to COVID-19 and may explain why they are more likely to die from the disease, scientists say. They suggest that drugs used to lower inflammation in the lungs could prove beneficial to obese patients with the disease.

September 10, 2020
Previous research has demonstrated a variety of health benefits associated with the Mediterranean diet, which is rich in olive oil, cereals, fruit and vegetables, fish, and a moderate amount of dairy, meat, and wine. Now results suggest that the diet may also help prevent rheumatoid arthritis in individuals who smoke or used to smoke.

Probiotics may help manage childhood obesity ... read more
September 7, 2020
Probiotics may help children and adolescents with obesity lose weight when taken alongside a calorie-controlled diet, according to a new study. The study found that obese children who were put on a calorie-restricted diet and given probiotics Bifidobacterium breve BR03 and Bifidobacterium breve B632, lost more weight and had improved insulin sensitivity compared with children on a diet only.

Offspring of mice fed imbalanced diets shown to be neurologically 'programmed' for obesity ... read more
September 4, 2020
Pregnant mice fed diets high in omega-6 fats and low in omega-3 fats are shown in a new study to produce offspring whose brains had a higher level of dopamine-producing neurons -- the neurological reward system. These mice went on to chase hyper-caloric diets, suggesting that the fats in a pregnant mother's diet may control the eating habits of her children, and potentially offering a new obesity-prevention strategy.
