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.
What is amazing is that our bodies and minds have become stronger, more resilient, and even shown signs of increased cognitive brain function, boosted immune function and general overall health as a result of forced or voluntary calorie restriction for periods of time.
This course covers intermittent fasting - the history, the great minds who have fasted but mainly the amazing and scientifically proven benefits to our health and well being - from living longer, brain health, immune system health, inflammation, weight loss and or control - the list goes on.
The course will also go into how to do fasting - the best protocols and frequency.
You will be astounded by just how amazing you feel once you start.
This lecture goes through the structure of the course and what students can expect to have learned by te end of the course
This lecture briefly describes what fasting is ... and what it is not.
This lecture outlines the benefits of fasting in an evolutionary context. How going without food for short periods actually made us stronger.
There are many great minds in history of our species, who have been active proponents of fasting, They have used it for cleansing, healing and mental clarity. They may not have known the science behind why it actually works but intuitively they felt the benefits. I will go through a few of them in this lecture.
In this lecture I will explore the concept of homoeostasis - this is natures way of keeping things in balance and can occur at many different levels, macro & micro. A natural variable like body temperature will fluctuate but kept in balance by a homeostat (like a thermostat) by sweating or shivering... an acceptable range of body temperature is maintained.
This lecture explores our energy systems - it is useful to understand because when we deny our bodies food, it has to adapt and make alternative plans to survive.
What doesn't kill us makes us stronger. This is an important adaptive concept when it comes to intermittent fasting
In 2016 Yoshinori Ohsumi won the Nobel prize for Physiology and Medecine for his discovery of the mechanisms of autophagy. Autophagy and apoptosis are key mechanisms for cleaning out old and dysfunctional cells and is kicked i when intermittent fasting.
This video is an introduction and outline to this section. The benefits of intermittent fasting are enormous and the consensus in the science is also very encouraging... enjoy
Longevity is living longer. There have been some amazing animal studies on the effects of fasting on longevity. Some animals have shown an increase between 15% and 60% when subjected to fasting regimens.
Whilst we can't always assume that animal studies will directly relate to human experience, so many of the physiological mechanisms are present in a wide range of species including humans.
This is lecture covers some of the science behind the effects of IF on longevity.This is quite a technical lecture, so if you are less interested in the technical side of the science, feel free to skip through to the next lecture.
Age related brain diseases are becoming more and more prevalent, partly because we are, as a species living longer. The research on intermittent fasting and brain health is extremely exciting. Brain health has to be a priority if we are going to extend our lifespans.
Intermittent fasting has also had great success in animal studies. Human studies are more sparse but what has been observed is the success of cancer treatment in conjunction with fasting.
Many of the studies of IF and cancer treatment have also revealed a surprising increase and improvement of overall immune function.
Inflammatory diseases are on the rise in modern western society. The normalisation of hormone balance, especially in relation to insulin, results in an overall reduction in inflammation. Studies on people partaking in the Ramadan fast month showed a significant reduction in inflammatory markers.
Increases in autophagy, apoptosis and mitochondrial biogenesis all have positive effects on heart health. The change in energy metabolism from glucose to fats also improves the HDL cholesterol profile of fasters.
Going without food for a period of time can be a great way to normalise some of your 'less healthy' eating habits. Fasting makes you extremely perceptive of how your body feels, both in terms of hunger and energy.. You will also find you will have a greater desire for healthy food choices rather than grabbing for fast or comfort food.
Many people are anxious that they might lose muscle mass as a result of fasting. In fact th exact opposite is true. Fat weight is lost and lean muscle is maintained or even increased.
Whilst much research has concentrated on longevity, brain health, heart health and cancer treatment, weight loss or weight stabilisation was observed in most studies. One simple reason is that the IF participants never make up the calorie deficit of a fasting period and so overall calorie is reduced overall.
There are many different ways to fast. This lecture outlines some of the most popular. Most methods have benefits; it is important you find one that you are OK with and is sustainable in your lifetyle.
Like the methods, frequency of fasting can come in many shapes and sizes. Again, find a frequency you can maintain.
I hope you enjoyed the course. Give fasting a try ... you won't regret it.
