Severe Diet Doesn’t Prolong Life, at Least in Monkeys

That was the headline for an article about “calorie restriction” in the New York Times on 8-29-12 (See link below). While researching the optimal diet for humans back in 2003, I explored many kinds of diet-styles, some of which would be labeled severe or extreme by the mainstream. They included fruitarian, raw-foodist and calorie-restriction.

Ultimately, I chose the whole foods, plant-based diet-style that was recommended by Dr. T. Colin Campbell, Dr. Caldwell Esselstyn, Dr. Neal Barnard and other prominent physicians that I know and respect. I was looking for a diet-style that would promote health, reverse disease and be relatively convenient for my lifestyle. I finally concluded that a simple and easy diet that reversed heart disease and type 2 diabetes was good enough for me. I later designed our 4Leaf concept around that premise as described by Dr. Campbell thusly:

The closer we get to eating a whole foods, plant-based diet; the better off we will be.

Rhesus monkeys didn’t fare too well on the CR diet.

What about the “calorie restriction” diet? That’s the “severe” diet that has been featured in the news this past week. Wikipedia defines CR as a dietary regimen that has been shown to increase both median and maximum lifespan in a variety of species.

But they point out that there has never been a randomized clinical trial of CR in humans. They mention the first study in primates, the one that began at the University of Wisconsin in 1989 and whose results were reported this week. From the article by Gina Kolata in the New York Times:

The results of this major, long-awaited study, which began in 1987, are finally in. But it did not bring the vindication calorie restriction enthusiasts had anticipated. It turns out the skinny monkeys did not live any longer than those kept at more normal weights. Some lab test results improved, but only in monkeys put on the diet when they were old. The causes of death — cancer, heart disease — were the same in both the underfed and the normally fed monkeys.

That’s certainly not good news from the calorie restriction folks, but I doubt they will change their eating habits because of it. There is a group called The Calorie Restriction Society that was formed in 1993 and I have included a link to their site below in case you’re interested. Here’s a paragraph about their philosophy from that website:

Calorie Restriction (CR) is the consumption of a diet with adequate quantities of all essential nutrients, except that the energy content of the diet (caloric intake) is safely reduced (by as much as 10-40%) below the amount of energy (calories) that the body would tend to naturally desire, absent any special dietary measures.

As any scientifically responsible review of research in the field of gerontology will quickly reveal, the only valid life-extension method that has any proven scientific backing behind it at all is Calorie Restriction (CR), from which “The Calorie Restriction Society” derives its name.

Dr. Roy Alford, shown here with Biosphere 2, where he spent two years. Is that a glass of milk in the picture?

While studying about the “optimal diet” for humans back in 2003, I discovered Dr. Roy Walford, who is one of the pioneers of the calorie restriction theory. Among other things, he was one of eight people who lived in Biosphere 2 for two years (91-93).

Although I respect much of his work and have read at least one of his books, I ultimately chose not to follow his regimen when it came to “calorie restriction.”Later I heard that he died at the age of 79.

From Wikipedia: Roy Lee Walford, M. D. (June 29, 1924 San Diego, California, USA – April 27, 2004) was a pioneer in the field of caloric restriction. He died at age 79 of respiratory failure as a complication of amyotrophic lateral sclerosis (commonly known as Lou Gehrig’s or motor neurone disease). He was a leading advocate of calorie restriction as a method of life extension and health improvement.

The Bottom Line and the Good News. With our recommended 4Leaf diet-style, you can eat all you want of the right food for humans—whole plants, still in nature’s package. That means no calorie counting, no constant effort to cut back on calories and certainly no calorie restriction. Another problem I have with the CR theory is that they appear to advocate seafood and dairy, which are simply not a part of our 4Leaf formula.
