July 9, 2019
New findings show that, on top of its benefits for metabolism, mood, and general health, exercise also improves brain function. In recent studies, researchers learned that obese and overweight individuals are prone to insulin resistance in the brain, where it provides information about current nutritional status, as well as the rest of the body. So researchers wanted to know whether exercise can improve insulin sensitivity in the brain and improve cognition in overweight individuals.

A tale of two proteins: The best and worst of metabolic adaptation ... read more
July 8, 2019
The Developmental Origins of Health and Disease hypothesis states that the nutritional environment in early life makes people susceptible to lifestyle-related diseases, such as obesity, diabetes and heart attack, as adults.
