Intermittent Fasting & Health


I found this article online that was SO interesting and really backs up the results that I have experienced with intermittent fasting. I have experienced not only an improvement in my appearance and weight but also a noticeable improvement in my health and how I feel on the inside. Blood test results also show remarkable improvements in my cholesterol levels. My doctor is thrilled with my improved health and has encouraged me to continue with intermittent fasting. 
My favourite quote from this article is: "The big surprise in the whole process was how easy the whole thing was. We realized that intermittent fasting and dieting had opposing attributes and disadvantages. Diets are easy in the contemplation, difficult in the execution. IF is just the opposite – it’s difficult in the contemplation but easy in the execution." 
SO TRUE!!!
Please enjoy a snippet from this article by Tim Ferriss below and read the full article here.
"Before the work on intermittent fasting, the only real strategy for extending the lives of laboratory animals was caloric restriction (CR). If rats or mice or even primates had their calories restricted by 30-40 percent as compared to those fed ad libitum ["at pleasure" = as much as they want] they lived 20-30 percent longer. The CR animals not only live 30 percent or so longer, they don’t develop cancers, diabetes, heart disease, or obesity. And these animals have low blood sugar levels, low insulin levels, good insulin sensitivity, low blood pressure and are, in general, much healthier physically than their ad libitum fed counterparts. But not so psychologically.
As we saw in the Keys semi-starvation study, caloric restriction isn’t much fun for humans, and it apparently isn’t all that much fun for the animals undergoing it either. When rats live out their ratty lives calorically restricted in their cages, they seem to show signs of depression and irritability. Primates do as well. If primates don’t get enough cholesterol, they can actually become violent. But they do live longer. Even though CR has never been proven in humans, based on lab animal experience it does work. So, if you’re willing to put up with irritability, hostility and depression, it might be worth cutting your calories by 30 percent for the rest of your long, healthy miserable life.
But could there be a better way?

An enterprising scientist decided to try a little twist on the CR experiment. He divided the genetically-similar animals into two groups, fed one group all it wanted and measured the intake, then fed the other group all it wanted – except every other day instead of daily. When the intake of the group fed every other day was measured, it turned out that that group – the intermittently fasted group – ate just about double on the eat days, so that overall both groups consumed the same amount of food. Animals in the one group at X amount of food per day while the animals in the other group ate 2X amount of food every other day. So both groups ate the same number of calories but the commonality ended there.
The intermittently fasted group of animals despite consuming the same number of calories as the ad libitum fed group enjoyed all the health and longevity benefits of calorically restricted animals. In essence, they got their cake and ate it, too. They got all the benefits of CR plus some without the CR.
Intermittent fasting (IF) reduced oxidative stress, made the animals more resistant to acute stress in general, reduced blood pressure, reduced blood sugar, improved insulin sensitivity, reduced the incidence of cancer, diabetes, and heart disease, and improved cognitive ability."

  2. The article was NOT written by Tim Ferris -- it is by Dr. Eades... on Ferris' site.

  3. Why does the blogger ignore Eades's conclusions? What is her response to them? Here are the last two paragraphs of the article:

    "It’s looking like the intermittent fast is another of those ideas in science that looks good in animal studies then not so good in human studies, proving once again that rats and mice aren’t simply furry little humans. And it appears – for humans, at least – that the intermittent fast is indeed beginning to look like the reality of a late-night gimmicky infomercial: long on promises, short on delivery. I suspect that it is also a cautionary tale about the applicability of caloric restriction studies to humans.

    "Sorry to be the bearer of bad news, but that’s the way science sometimes works. Lab results and reality are often two different animals."
