Researchers at Université Laval have discovered a natural molecule called protectin DX (PDX) that improves insulin sensitivity and reduces blood glucose levels in obese diabetic rats. PDX triggers the production of interleukin-6 (IL-6) in muscle cells, similar to exercise, but its efficacy may be comparable to certain diabetes drugs.
A study of healthy senior men found that intense endurance exercise confers cardiac benefits regardless of age. The research, published by the European Society of Cardiology, indicates that 40 is not too old to start endurance training and that the heart remains amenable to modification through exercise even at this age. This finding s...

A new study suggests that shivering and bouts of moderate exercise can convert energy-storing 'white fat' into energy-burning 'brown fat'. This process could protect against diabetes, obesity, and fatty liver. The conversion is triggered by the hormones irisin and FGF21, which are stimulated by cold exposure and muscle activity.
Research found that shivering releases irisin, a hormone that stimulates calorie-burning brown fat and improves metabolism. This mechanism is similar to exercise-stimulated secretion of irisin, suggesting potential benefits for treating or preventing obesity.
