Balanced diet, exercise may not prevent gestational diabetes ... read more
January 7, 2019
A new study is the latest evidence that the 'first-line' strategy for preventing gestational diabetes mellitus isn't working. Over the past five years, more than 5,000 pregnant women took part in clinical trials focused on limiting weight gain in order to prevent gestational diabetes. The moms-to-be improved their diet quality, ate less, and increased their physical activity. They also developed gestational diabetes at about the same rates as the women who didn't change their diet or activity levels.

December 11, 2018
It is well known that poorer Americans are more likely to be obese or suffer from diabetes; there is a strong negative correlation between household income and both obesity and diabetes. This negative correlation, however, has only developed in the past 30 years, according to researchers. Since 1990, the rise of obesity and diabetes was fastest among the poorest US regions.

Study links frequent red meat consumption to high levels of chemical associated with heart disease ... read more
December 11, 2018
Researchers have identified another reason to limit red meat consumption: high levels of a gut-generated chemical called trimethylamine N-oxide (TMAO), that also is linked to heart disease. Scientists found that people who eat a diet rich in red meat have triple the TMAO levels of those who eat a diet rich in either white meat or mostly plant-based proteins, but discontinuation of red meat eventually lowers those TMAO levels.

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.

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.
