India Times -- A new study has suggested that restricting fatty food may not lengthen the life span, as was widely believed, but may have a contrary effect, i.e. shortened life. Researchers at the UT Health Science Center San Antonio’s Barshop Institute for Longevity and Aging Studies, with colleagues at the University of Colorado, studied the effect of food restriction on fat and weight loss in 41 genetically different strains of mice. The scientists then correlated the amount of fat reduction to life span.
