Can a reduced calorie diet affect aging?
If you were told you could live 40% longer but you would have to go on a reduced calorie diet for the rest of your life (that means no more of that fatty oh-so-good junk food we all love once in a while) --- would you do it?
According to the NY Times article, One for the Ages: A Prescription That May Extend Life, calorie restriction (ie. eating 30% fewer calories than what is normal for your specific body type, gender, age) and its effect on the aging process has been a hot topic among scientists. Currently, “calorie restriction is the only strategy known to extend life consistently in a variety of animal species.” Of course, the studies have involved experiments on only animals--- not humans—but the results seem to be consistent despite the different species used in the experiments. Those animals – no matter what their species—who had a reduced calorie diet seemed to age less quickly--- and suffer from age-related diseases—than those that were given a normal diet.
One scientist went so far as to say “calorie restriction may be more effective than exercise at preventing age-related diseases.” Better than exercise? Wow.
However, a calorie restriction diet is not a new concept. "In 1935, Dr. Clive McCay, a nutritionist at Cornell University, discovered that mice that were fed 30 percent fewer calories lived about 40 percent longer than their free-grazing laboratory mates. The dieting mice were also more physically active and far less prone to the diseases of advanced age.”
One thing that should be brought up, especially in this day & age where “bones are in,” is that a calorie reduced diet does NOT mean the individual doesn’t eat or have his/her daily amount of vitamins, minerals and other nutrients.
While calorie-restricted diets are still debatable and may not be for some, you should at least be aware of it. However, before you go on ANY diet, first consult with your doctor.
