“Carb Loading” is surely not what we all did for millions of years?

 

Many of you who take serious exercise believe in “Carb Loading”. But please step back for a moment. How did our ancestors who ran down prey – who used their bodies all day do all of this without carbs – for they did not have them? They used our primal fuel – fat.

The Problem: The Basic Assumption of the Carb Paradigm is Wrong

Glucose is not the preferred fuel of muscle cells under normal human resting metabolic conditions or even under most normal human movement patterns (exercise). Fat is. Sure, given an unlimited supply of glucose and regular refilling of glycogen stores, skeletal muscle will burn through it during exercise the same way a fire burns through kindling when that’s all you have to offer. The body can shift carbohydrate oxidation to keep up with intake. But skeletal muscle can burn fat with great efficiency (and far less oxidative fallout) at relatively high outputs for very long bouts. Cardiac muscle actually prefers ketones, and the brain can run just fine (maybe even optimally) on a blend of ketones and minimal glucose.  Our survival as a species has depended on these evolutionary adaptations away from glucose dependency. Entire civilizations have existed for ages on what is practically a zero-carb diet. Think about this: there is actually no requirement for any “essential dietary carbohydrates” in human nutrition. It’s possible to live a very long and healthy life never consuming much – if any – in the way of carbs, provided you get adequate dietary protein and fat. The same can’t be said for going too long without protein or fat. Cut too far back on either of those macronutrients and you will eventually get sick and die.

What is the Missing Human Manual All About?

Do you want to age well? Most of us do. If you are my age, 60, this is more important a question that if you are 30. But most of us would not wish to have heart disease, cancer, dementia when we get old.

Most of us think it is normal that we will get ill like this.

But science today tells us that this is not "Normal". Our evolutionary past designed us to be active and fit until we drop dead. Why? Because raising human children takes so long. Mature adults had to do most of the hard work enable us to invest up to 25 years in our kids.

We are designed by our evolution to reach a plateau of fitness in mid life. So why do most of us not live like this?

We don't because, we have strayed away from the best way of living that fits our evolution best. Our culture has got too far ahead of our biology. We eat foods that make us ill. We have lost our social identity and power and that makes us ill. And we have lost touch with the circadian rhythms of the Natural World, and that has made us ill too.

We have lost our fit with our true nature.

This site will be a Manual. It will show you what the best fit is. It will show you the science behind this. It will share with you some methods for getting your fit back with your true human nature.

So welcome to the "Missing Human Manual" . I hope that we can help you and I hope that you can help others as a result.
