As more people live sedentary lifestyles, it seems that any type of movement may be good for us. A recent study published in the American Journal of Preventive Medicine suggests that fidgeting, traditionally considered unacceptable in some circles, could decrease the risk of mortality in those who sit for much of the day.

Researchers say fidgeting may help counteract the the negative health implications of sedentary behavior.

The study, led by researchers at Leeds University and University College London, both in the UK, builds on.

Dietary fiber is a plant-based nutrient that is sometimes called roughage or bulk. It is a type of carbohydrate but, unlike other carbs, it cannot be broken down into digestible sugar molecules. Therefore, fiber passes through the intestinal tract relatively intact. However, on its journey, fiber does a lot of work.

A study from the US National Institutes of Health presents some of the most precise human data yet on whether cutting carbs or fat has the most benefits for losing body fat.

Since 2003, Kevin Hall, PhD--a physicist turned metabolism researcher at the National Institute.

One day soon, doctors may determine how physically active you are simply by imaging your brain. Physically fit people tend to have larger brain volumes and more intact white matter than their less-fit peers. Now a new study reveals that older adults who regularly engage in moderate to vigorous physical activity have more variable brain activity at rest than those who don't. This variability is associated with better cognitive performance, researchers say. The new findings are reported in the journal PLOS ONE. "We looked at 100 adults.
