In countless experiments, every animal that has ever had a limited calorie diet has lived longer as a result.
Guinea flies, mice, rats, rabbits, pigs and dogs all live on about a third if they are fed less. For humans, this translates to about 25% longer lives. So, for example, instead of dying at 80 you can expect to live up to 100 if you reduce your food intake.
In addition to living longer, all tested animals have more zip and get-up-and-go, so they look and behave younger.
The message is simple: If you want to live longer ... eat less.
But why is this so?
Delays cell division
Researchers at the University of Washington in Seattle have shown that this is because limiting calorie intake slows down the rate at which cells divide.
Cell age is measured in terms of the number of parts that have passed through and not over time. If you slow down cell division, you are slowing down as the lesser cell parts are less telomeres as discussed in the previous article How to Beat Aging (1) .
Telomeres is a string of DNA repeats located at the ends of a pair of chromosomes in a cell that protects the chromosome. Each time the cell divides its telomer is shortened. The maximum number of cells can vary from 50 to 60 depending on the type of cell involved.
Eating slows down cell division, which is the length of time between parts, and so you live longer.
But is it worth it?
Limiting your calorie intake is difficult
To live longer by limiting your calorie intake, you need to permanently reduce your intake to about two-thirds of the calories needed to maintain your current weight.
Losing the weight you experience initially will increase as your metabolism adjusts.
This anti-aging strategy is simple but not easy to implement.
To begin with, it was very difficult. In addition, your metabolic rate will decrease, you will get smaller and your sex hormones will decline which will block your sex drive. You may begin to lose sexual features such as body hair and breast development.
All the scientific studies done so far on a limited calorie diet only involve animals whose lives are relatively short in human terms. There are no controlled studies of the long-term effects on people with these diets as they require subjects to monitor throughout their life.
However there was a group of people called ' 'cronies' (which means calorie restriction with optimal nutrition ) who use themselves to test the effects of a long-term restricted calorie diet.
They monitor vital signs as they look for drops in glucose, blood pressure, cholesterol and temperature to ensure their diet works. Monkeys and rats on a restricted calorie diet experienced similar decreases in these measures.
Obviously the crony's Excessive diets will prolong their life but at the cost of most things are fun and worth living.
Is there a better way to live?
Short-term restrictions on calorie intake
Short-term calorie restriction means fasting one or two days a month regularly.
In September 2001, a study was published in Malaysia Proceedings of the National Academy of Sciences in the United States, it is revealed that short-term calorie restriction actually lasts a lifetime, for at least rats.
Scientists have found that short-term restrictions on food intake occur rapidly in 11,000 mouse rats. Younger effects are even seen in older mice that have never released their calories.
Short-term fasting has the continuing benefits of anti-aging according to scientists ... it triggers an increase in the production of human growth hormone (HGH), one of the most important anti-aging hormones that, unfortunately, declines dramatically after 30 years. HGH will be discussed in a future article.
Avoid eating too much
As scientists found out more about how the mechanism of calorie intake affects aging, they came to the conclusion that eating too much speeds up aging.
There are a few things you can do to avoid eating too much:
- Avoid high calorie foods
- don't eat late at night
- stop eating early (leave food on the plate)
- do not eat when disturbed (for example, watching TV)
- run short term fasts for one day or more each month.
Diet is anti-aging --- Over-eating is speeding up your life
