"The average age of the Kenyans was 21, and mean height was 1.75 meters (~5' 9"), with remarkably little variation in stature (the shortest individual was 1.70 meters, the tallest 1.80 meters, which meant that the smallest and greatest heights were just three percent away from the mean)."
The average age is 21 of these athletes is... keep a person on that kind of diet above, and lets see how well they fair as the years pass.
Natways Arguement: Because 21 year old kenyans can perform exceptionally at marathons on a diet mostly of calories, it MUST be healthy.
This a complete STRAWMAN. But as usual... natway likes to grasp at straws. Just because a 21 year old takes steroids and can tip over cars, doesn't make it healthy. Its the same thing with all that sugar. I have yet to see any kind longevity study toting the benefits of this kind of diet.
Aswell the kenyans also ate meat 4 times a week... the 80-10-10 diet is a vegan diet. Vegans do not eat meet even once a week, let alone 4 times. Saying that meat eating Kenyan Marathon runners are exemplifying the greatness of the 80-10-10 vegan diet is absolutely absurd.
So what if you say ratio... the 801010 ratio was coined by a VEGAN! It means VEGAN.
How do I know you meant vegan too... by this logic
#1, you clearly have an agenda against the Paleo diet which you have previously demonstrated
#2. you clearly support the high calorie vegan diet which you have previously demonstrated
So clearly you weren't just mentioning 801010 out of some sort of random thought.
You are also arguing against a paleo diet, in a paleo diet debate forum, with a diet of keynan marathoners that includes MEAT AND DAIRY. This is just HILLARIOUS!! why on earth you decided to argue in favour of a vegan diet using a the diet of the kenyans that includes MEAT AND DAIRY is complete ABSURDITY.
I also don't need to post all the world class paleo runners, because you already did for me. GO MEAT EATING KENYANS!!! The fact that people eating animal protein are winning all the worlds races is awesome!!!
