| Recent
studies introduces two major influences on aging process.
The first is calorie restriction and the second one's insulin level.
"We found that within just 48 hours of being switched from
a
high nutrient intake to dietary restriction, flies were no more
likely to die than those that had been under dietary restriction
constantly throughout their adult life," says one of the study's
authors, Linda Partridge, a professorial fellow in the department
of biology at University College London.
Calorie restriction is
the only well-researched, effective means of
retarding aging that is available to post-embryonic animals.
Only one intervention has been proven to extend both the average
and maximum lifespan of all animal species tested: reducing the
consumption of dietary calories, or caloric restriction (CR). [1-2]
While widely recommended, exercise and nutritional
supplementation have not been shown to extend maximum lifespan.
[3-5] Because CR extends maximum lifespan, scientists believe it
actually slows the process of aging. CR is therefore used as a
means to study the process of aging.
Calorie restrictions not
the same as "going on a diet," or simply
eating less, or starving oneself. Simply eating a very low-fat diet
could actually amount to mild calorie restriction. Indeed, as
indicated above, the purported benefits of very low-fat diets may
result partly, if not primarily, from the almost inevitable
reduction in energy intake entailed by this way of eating. Another
easy way to practice mild calorie restriction would be to get into
the habit of not eating to complete satiety.
Another way to practice
mild calorie restriction is simply to skip
lunch. This is probably the easiest way to practice mild calorie
restriction. An additional potential benefit of skipping lunch is
the prevention of late afternoon fatigue. A recent study suggested
that this benefit could be quite striking.
A suggested method of
fasting is the following: Do not eat till the
dinner time. Try it for a week and then skip it for three weeks.
If
you can go on with it, keep it for as long as you can till it becomes
a habit. We may suggest putting fish, olives, fresh fruits, multi
grain bread before anything else in your shopping basket for a
healthy skin. If you are to buy only one supplement, try grape seed
extract.
