A diet with 30% fewer calories than normal preserved the interest and ability in laboratory rats to move around as they aged -- an effect also seen with exercise, researchers said here.
Among 1-year-old rats with relatively high activity levels at baseline, almost no reduction was seen over the next 18-24 weeks when kept on the low-calorie diet, whereas rats allowed to feed freely showed an approximately 25% reduction in activity (P<0.05), said Michael Salvatore, PhD, at Louisiana State University's campus in Shreveport. http://www.medpagetoday.com/MeetingCoverage/SFN/42854
