Meal Skipping Helps Rodents Resist Diabetes, Brain Damage

A new mouse study suggests fasting every other day can help fend off diabetes and protect brain neurons as well as or better than either vigorous exercise or caloric restriction. The findings also suggest that reduced meal frequency can produce these beneficial effects even if the animals gorged when they did eat, according the investigators at the National Institute on Aging (NIA). ?The implication of the new findings on the beneficial effects of regular fasting in laboratory animals is that their health may actually improve if the frequency of their meals is reduced,? says Mark Mattson, Ph.D., chief of the NIA?s Laboratory of Neurosciences.

Energy bars may not help low-carb dieters

A new study reports that energy bars with low or moderate levels of carbohydrates may actually not help dieters lose weight as they promise to do. Proponents of several diet plans ? such as the Atkins and Zone diets ? say low or moderate carbohydrate foods lead to less of an insulin spike in the blood after meals, which helps lead to people burning more fat and losing more weight. However, this new study found that energy bars advertised as having low or moderate levels of carbohydrate don’t actually reduce insulin levels in the blood as much as expected. The bottom line is that these energy bars may not contribute to weight loss, at least not in the way that manufacturers are advertising they do.
