Yes, you must not have been hearing it for the first time, calorie reduction is just one key to living longer if and only if you live in non-mosquito endemic environments like Africa. But many writers, motivational speakers and other non professionals in medicine/paramedicine just overemphasis this fact. Just try putting a control on your appetite. But sincerely speaking I think longevity is more of an issue of lifestyle and environment than of just calorie reduction. Nothing more nothing less. Where calorie reduction is captured by lifestyle.
