Paleo Diets
The up surge of information on Paleo diets and how they are beneficial to your body revolves around the concepts of no processed foods, limited farmed grains, plenty of protein and intermittent fasting.
As highlighted in this article below, the concept of eating 3 square meals a day, evolved around the evolution of agriculture. That is, around 10,000 years ago. Prior to that, is the concept of Paleo - eat what is available by hunting and gathering, with limited cooking. That, essentially, is Paleo!
Read on to learn more about the concept of intermittent fasting and the science behind it and why it's successful:
Beyond Detox: How Fasting "Cleanses" Your Cells
In what is yet another clue that performing Isagenix-style Cleanse
Days can be profoundly good for you, nutrition scientists are now
encouraging the occasional fast or skipping of meals for better health.
Fasting periodically might also bring the added benefit of
“cleansing” cells of junk and debris, according to researchers in a
review paper published in the November issue of the scientific journal,
Proceedings of the National Academy of Sciences.
“Cells possess dedicated mechanisms for the removal of damaged molecules and organelles,” the authors wrote
.
Challenging the notion that a typical “three square meals a day”
regimen should be considered a standard of healthy eating, the authors
wrote that giving cells a steady supply of nutrients in this way keeps
cells in “growth mode.”
While in continuous growth mode, cells have little chance of going into a cleansing mode that involves a couple of mechanisms:
- The first is a sort of molecular “tagging” of proteins that targets
them for recycling and re-using their amino acid building blocks by a
protein degradation complex known as a proteasome.
- The second is autophagy whereby damaged molecules and organelles are “cleansed” from cells by lysosomes, those membrane-enclosed organelles full of acids and digestive-like enzymes.
Among the authors of the paper were leading scientists from around
the world in the field of intermittent fasting, time-restricted feeding,
and calorie restriction.
They included Krista Varady, Ph.D., of the University of Illinois at
Chicago (UIC), who was the lead researcher of a study evaluating the use
of the Isagenix system comprising of intermittent fasting (Cleanse
Days) combined with calorie restriction (Shake Days).
The Isagenix study, in fact, was included as one of the references in
the article as evidence that intermittent fasting combined with calorie
restriction could lead to weight loss, which resulted in suppressed
inflammation in the body.
Additional studies from Dr. Varady’s lab and those of Mark Mattson,
Ph.D., of the National Institute on Aging, have shown that calorie
restriction and, intermittent fasting especially, improved insulin
sensitivity while boosting fat metabolism.
Furthermore, these dietary approaches could lead to the elevation of
ketones in the body. Ketones are chemicals produced during the breakdown
of fat and are known to provide some benefits against brain aging.
Moreover, intermittent fasting in animals has led to production of
several brain-protective proteins, improved mitochondrial function, and
stimulation of the activity of key antioxidant enzymes such as
superoxide dismutase and catalase.
To obtain the benefits of calorie restriction and intermittent
fasting, the authors advocate an eating pattern modeled after our
hunter-gatherer ancestors who ate less frequently. Historically,
hunter-gatherers, both ancient and modern, rarely suffered from obesity
and functioned at a high level physically and mentally.
According to the authors, the pattern of “three square meals a day”
began only after the advent of agriculture 10,000 years ago as a result
of a continual year-round food supply. “Our agrarian ancestors adopted a
three meals a day eating pattern, presumably because it provided both
social and practical benefits for the daily work and school schedules,”
the authors wrote.
One of the contributing factors to obesity, they argued, was the
adoption of sedentary lifestyles combined with multiple high-calorie
meals daily.
Another cause of overeating may also be the advent of artificial
light and how it affects our internal circadian clocks, which are
intended to function on a daily light-dark cycle. The increase in hours
awake leads to more opportunities to overeat while also interfering with
the sleep/wake and fast/feed cycle that may be a key factor in
regulating appetite and metabolism.
With the adoption of a dietary pattern that incorporates periods of
fasting, calorie restriction, or both—such as an Isagenix system—along
with exercise, healthy eating, and proper sleep, the authors suggest a
number of health benefits including reduction of abdominal fat and
improved metabolic and cardiovascular risk markers.
