Obesity, risk of cognitive dysfunction? Consider high-intensity interval exercise ... read more
December 10, 2018
Researchers have discovered what might be an effective strategy to prevent and combat cognitive dysfunction in obese individuals. They are the first to examine the modulatory role of an exercise-induced protein in the brain that promotes neuron survival and used high-intensity interval exercise (HIIE) in obese and normal-weight subjects. Obesity reduces the expression of this protein and lower levels are associated with Alzheimer's, Parkinson's and obesity. HIIE upregulated this protein in the obese subjects compared to normal-weight subjects.

Blood vessel growth key to healthy fat tissue, research shows ... read more
December 4, 2018
New research shows that inhibiting a protein within blood vessels stimulates new blood vessel growth, resulting in healthier fat tissue (adipose) and lower blood sugar levels. The findings provide key insight into how improving blood vessel growth could help to mitigate serious health problems that arise with obesity, such as diabetes.

Gene that lets you eat as much as you want holds promise against obesity ... read more
December 4, 2018
It sounds too good to be true, but a novel approach that might allow you to eat as much as you want without gaining weight could be a reality in the near future. When a single gene known as RCAN1 was removed in mice and they were fed a high fat diet, they failed to gain weight, even after gorging on high fat foods for prolonged periods.

Study in mice suggests drug to turn fat 'brown' could help fight obesity ... read more
November 26, 2018
Our bodies contain two types of fat: white fat and brown fat. While white fat stores calories, brown fat burns energy and could help us lose weight. Now, scientists have found a way of making the white fat 'browner' and increasing the efficiency of brown fat. While their study was carried out in mice, they hope that this finding will translate into humans and provide a potential new drug to help fight obesity.

Weight likely cause for one-fourth of asthma cases in kids with obesity ... read more
November 26, 2018
A study including health data for more than 500,000 children in the US suggests obesity might be to blame for about a quarter (23 to 27 percent) of asthma in children who are obese. This could mean about 10 percent of all kids ages 2 to 17 with asthma -- almost 1 million children in the US -- might have avoided the illness by maintaining a healthy weight.

Gut hormone and brown fat interact to tell the brain it's time to stop eating ... read more
November 15, 2018
Researchers have shown that so-called 'brown fat' interacts with the gut hormone secretin in mice to relay nutritional signals about fullness to the brain during a meal. The study bolsters our understanding of a long-suspected role of brown adipose tissue (BAT) -- a type of body fat known to generate heat when an animal is cold -- in the control of food intake.

In a new paper, researchers with diverse expertise and perspectives on the issues laid out the case for each position and came to a consensus and a future research agenda.

Should you eat a low-gluten diet? ... read more
November 15, 2018
When healthy people eat a low-gluten and fiber-rich diet compared with a high-gluten diet they experience less intestinal discomfort including less bloating which researchers show are due to changes of the composition and function of gut bacteria. The new study also shows a modest weight loss following low-gluten dieting. The researchers attribute the impact of diet on healthy adults more to change in composition of dietary fibers than gluten itself.

Big change from small player: Mitochondria alter body metabolism and gene expression ... read more
November 9, 2018
Mitochondria have their own DNA, but the 13 genes in human mitochondria -- along with DNA sequences for tRNAs, rRNAs and some small peptides -- are massively overshadowed by the 20,000 genes in the human nucleus. Nevertheless, these diminutive mitochondria may have a strong influence on cellular metabolism and susceptibility to metabolic diseases like heart failure or obesity.

Gut microbiota of infants predicts obesity in children ... read more
October 23, 2018
Evaluating the gut microbiota of infants may help identify children who are at risk for becoming overweight or obese. The research revealed that gut microbiota composition at two years of life is associated with body mass index (BMI) at age 12. In addition, the BMI at age two was not significantly higher in children who later became overweight/obese, indicating that gut microbiota composition may be the earliest warning sign for detecting obesity.
