If you don't know much about the primal diet it is sort of based on the low carb or Atkins diet. The idea of the diet is to reduce the amount of carbohydrates in one's diet.
When carbohydrates are reduced or eliminated from the diet the body is starved for energy and can not survive. Every single cell of the trillions that make up a living body requires carbohydrates all the time. In order to overcome this the body will turn protein and fat into carbohydrates.
This process creates ketones. These ketones are toxic and the body must eliminate them along with all of the other metabolic toxins. This requires a lot of extra work for the body and these extra toxins can cause diseases.
This process is a survival process and not a normal process. Normally our body was designed to consume vast amounts of natural carbohydrates and use them for fuel.
Mark Sisson has a question and answer page on his website. Here is one particular question and his answer following it:
What is your health philosophy?
Really, my health philosophy is surprisingly simple. I follow a diet based on an understanding of evolutionary science. I think it’s more important to eat, move, and live according to how humans are designed and not according to society’s artificial developments of the last 100 years. Fortunately, this regimen is not only incredibly healthy, it’s quite simple.
In a nutshell:
- fresh, organic, unprocessed food – no junk!
- daily activity – whether it’s the gym or a walk along the beach, it all counts
- plenty of quality sleep
- plenty of water, no soda or sweetened drinks
- antioxidants galore – the key to limiting stress
- a good fish-oil supplement
- lots of essential fats, reckless amounts of vegetables, and clean protein
- time for fun – don’t take anything too seriously – ethical behavior – because what goes around comes around
- taking responsibility for yourself and your life – openness to new things and ideas
This is where I have a problem with Mark. He mentions that we need to eat fresh, organic and unprocessed food. He then recommends eating moderate amounts of animal flesh. Animal flesh can only be fresh if you kill the animal yourself. I don't think Mark is out in the woods right now slitting a deer's throat.
I don't know where he gets his supply of animal flesh but certainly it can't be fresh unless he kills the animal himself. Organic for animal flesh is really a big lie. There are no organic guidelines for animal flesh. Most meat that is sold as organic is really the same as the factory farm meat. It's not easy to force animals to eat organic food, they will eat whatever they find. All meat has to be processed or it will putrefy in a short time. No meat is unprocessed unless it is eaten as soon as it is killed. For example a lion will take down an antelope and eat it within minutes. The lion will consume everything from head to hoof and eat it raw. Humans just do not seem to want to do this.
He says to get plenty of quality sleep. Further down the page he said that he sleeps 7 hours a day. The recommendation for sleep is 8 to 10 hours by every health organization around. He obviously is not even following his own advice.
In order to get antioxidants (galore) someone needs to consume a lot of colorful plant foods like fruit and vegetables. Meat and animal products contain none to a trace of antioxidants. If you are recommending people to eat animal flesh then you can't at the same time recommend they eat antioxidants (galore), because that is a conflict.
The part about ethical behavior is self explanatory. How can you consume thousands of harmless sentient animals, destroy the environment and recommend that others do the same and call that ethical. I believe that he is right however on the part about what goes around comes around, so Mr. Sisson, remember you said that and not me.
These are just a few of the inconsistencies of a supporter of the low carb or primal diet. If you read a few more of his webpages you'll find many more.
