Dr. Mercola's Comments:

As I said last year:

Anti-aging medicine has never been a major interest of mine. I have heard of calorie restriction as a potent way to slow down the aging process, but I never paid much attention to this type of research.

However, last July I had the privilege of attending a lecture by Dr. Ron Rosedale at Designs for Health Institute's BoulderFest Seminar. Dr. Rosedale helped me understand the importance of grain restriction five years ago and at this seminar he opened my eyes once again.

He is convinced that most disease is an artifact of the RATE at which we age. There appear to be two potent influences on this aging rate. One is the amount of food one eats (as mentioned above) and the other is one's insulin level.

A low grain, no sugar eating plan is one of the most effective ways to lower one's insulin level. This is especially effective when combined with an aerobic-type cardiovascular exercise program. Ideally, one should increase his/her heart rate to about 75 percent of its maximum rate and maintain the rate for 45 minutes, five times a week.

I have been monitoring my patients' insulin levels for the past few months and am now convinced that exercise is a potent method to reduce one's insulin levels.

The other major perspective shift I learned from Dr. Rosedale is that it is likely very healthy to fast occasionally.

What is the take-home practical benefit from this?

Well, how many of us have been faced with trying to follow the eating plan at a party or restaurant where there are just no good food options available?

Guess what the other option is?

Don't eat anything. You can reframe this very positively as, I mentioned previously, occasional fasting is a healthy practice for most people. So you can tell yourself that making this choice will actually improve your health and allow you to live longer.

I have actually applied this a number of times very successfully when I have been traveling and there are no healthy breakfast options. Alternatively you could use Whey Healthier, a high quality protein drink in a very convenient format that I recommend highly and regularly use.

Lowering your insulin levels may be the fountain of youth. Consuming sugar and grains will increase your insulin level, and that is the equivalent of slamming your foot on the aging accelerator. There is simply no more-potent way to accelerate aging than eating sugar and grains.
