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.

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.

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

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.

Study focuses on low-carb, high-fat diet effect on older populations ... read more
August 20, 2020
Medical researchers noted improvements in body composition, fat distribution and metabolic health in response to an eight-week very low-carbohydrate diet. Older adults with obesity are at particularly high risk of developing cardiometabolic disease such as Type 2 diabetes and cardiovascular disease. Rather than total fat mass, deposition of fat in certain areas, such as the abdominal cavity and skeletal muscle, may confer this greatest risk of disease development.

How protein protects against fatty liver ... read more
August 18, 2020
Non-alcoholic fatty liver disease is the most common chronic liver disease in the world, with sometimes life-threatening consequences.
