CR Versus Exercise, Round 2

Fight Aging!

Do you want to live a longer life in good health? Simple practices can make some difference, such as exercise or calorie restriction. But over the long haul all that really matters is progress in medicine: building new classes of therapy to repair and reverse the known root causes of aging. The sooner these treatments arrive, the more lives will be saved. Find out how to help »

Last time, the spin was that calorie restriction (CR) is more beneficial to health than exercise; this time it's sensibly mixed: "Those who dieted lost muscle mass while those who exercised did not. This is because exercisers routinely challenged their muscles, which prevented muscle tissue from degrading. Dieters didn't work their muscles as vigorously as those who exercised. ... It's important that dieting not be seen as a bad thing because it provides enormous benefits with respect to reducing the risk of disease and is effective for weight loss. Furthermore, based on studies in rodents, there is a real possibility that calorie restriction provides benefits that cannot be achieved through exercise-induced weight loss." So then, as before, and as CR practitioners do, the best way forward would seem to be some combination of CR and exercise, not one or the other.
