Weight-reduction surgery for severely obese adults may prevent second heart attack, death ... read more
October 26, 2020
Adults with severe obesity (BMI >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.

Fatter legs linked to reduced risk of high blood pressure ... read more
September 10, 2020

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.

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. A high-protein, calorie-reduced diet can cause the harmful liver fat to melt away -- more effectively than a low-protein diet. A new study shows which molecular and physiological processes are potentially involved.
