In this course we will take a close look at fasting and the evolutionary adaptations, humans and many other species have made to counter the effects of reduced calorie intake. 

We will also look at the history of fasting and some of the greatest minds who used fasting for health, energy and mental clarity. 

Our eating habits are exactly that - habits. 
What and how we eat is a behaviour - the same as many of the other behaviours we have that make us - US.

Many of our habits we are totally ok with - they don't invoke any feelings of guilt or anxiety. Some of our habits are truly beneficial and we should feel proud we have made them a habit...

One of the trickiest habits or behaviours we own, relates to Food. That's because our eating behaviour is shaped by so many emotions,desires and feelings... both good and bad.
It is interesting that humans are pretty much the only animal on the planet that don't really know what we are meant to be eating. What is human food. A panda bear has no question that it's primary preferred food source is bamboo shoots. A lion or leopard knows that a zebra, gazelle or wildebeest are perfect food - we are not entirely sure if they actually have a preference. White sharks definitely fancy the taste of seals.
So why are humans so confused.
Well there are a couple of reasons. Firstly we are the great colonisers - there's hardly a space on the planet we haven't managed to colonise and survive - we had to adapt to whatever foods were available.

There are very few of us in the western world who have experienced what it is like to be truly hungry. And quite right - it is sad that any human beings in this day and age should have to experience hunger.

Having said that, we have, as a species over the course of evolution, experienced hunger, sometimes for extended periods.
