Skipping meals may not be as detrimental to health as is widely believed; in fact, it may protect us from diabetes and Alzheimer's, new findings in mice indicate. In a study led by Dr Mark P. Mattson of the National Institute on Aging in Baltimore, Maryland, mice that ate only every second day appeared to fare better than those who ate as much as they wanted or were kept on a restricted calorie diet, eating 40% fewer calories less than the other two groups. The mice that were only allowed to eat every other day were able to eat as much as they wanted on the second day, with the result that their overall calorie intake was as high as those who were allowed to eat as much as they chose to every day.
