Question on Fat Loss
Name: Bruno
Well, what to say? ...
I'm quite fascinated with the idea of hibernation diet and would like to try it out sometime in the future, but I'm also a bit sceptical when it comes to the fat-losing part. I'm a recreative bodybuilder and this "revolutionary" discovery could really help me out.
So, I would like to know if there are some valid and published researches to back this theory and its statements up?
Thanx in advance!

Hello Bruno,
The answer to your question is no, no such direct studies have been undertaken.
However in terms of the science all of the principles (and there are many) are sourced from the literature, some of the studies going back many decades.
These very simple principles have been missed by all those involved in weight loss, from the medical profession, through nutrition and dietetics and include the sport science faculties.
There are 5 key princilpes in human biology;
1. The fuel demand of the human brain.
2. The fuel capacity of the liver.
3. The rate of depletion of the liver during resting metabolism.
4. The rate of depletion of the liver during exercise.
5. The fuel used to furnish the energy required for recovery biology.
In the course of my work, in sport biology, I discovered that none of these principles are taught in medical school.
Nor are they taught in the related faculties, nutrition and dietetics or in the faculties of sport science.
This is an amazing claim to make but I have confirmed it time and time again.
I speak to athletes on a daily basis and this includes those qualified in these disciplines.
If you are unaware of these questions then you would not be aware of why it is so vital to refuel the liver prior to bed to provide glucose for the brain during the night fast.
All recovery biology is fuelled by fat and this fat is body fat as opposed to muscle fat.
Exercise uses both muscle and body fat in a 50/50 ratio, so that in an hour of aerobic work we may burn some 600 calories, but at 20% this comes to 120 fat calories and fat contains 9 calories to the gram, the maths come to some 13.3 grams of fat.
Half of this fat is sourced from muscle fat stores, so the body fat used is around 6.6 grams (less than quarter of an ounce).
Nobody in any gym in any country of the world is going to be informed of this but the science is clear.
Now we can understand why millions of people go to the gym and soon become demoralised.
The exercise regime they undertake is extremely inefficient from the perspective of burning fat (body fat in particular).
The muscle fat store is reserved from exercise only so during recovery biology the fat used is 100% body fat, therefore with a basis metabolic rate of 100 calories per hour at rest some 70 fat calories should be consumed and these are all body fat calories.
overnight some 560 fat calories and divide my 9 and we arrive at 62.2 grams overnight, that is some 10 times the amount in the gym for an hour's sweat.
Again provided the liver is fuelled prior to bed.
Resistance exercise is more efficient in terms of fat burning because resistance exercise (as opposed to aerobic) increases EPOC (Excess Post Exercise Oxygen Consumption) and if you are using oxygen something is being burned and that something is body fat.
When the book has been attacked, as it has been from two dietiticians and one nutritionist, it is from the perspective of those who are unaware of the above 5 principles.
When confronted with the science they are horrified to discover that their knowledge is based more on assumed tenets they never thought to question.
If you do not understand these principles it smply means that you are unaware of the partition and selection of fuels during rest and during exercise.
Nobody told them in a lecture theatre during their studies exactly how and why these questions are so significant and therefore they are left with the popular conceptions of fat metabolism, which amount to no more than prejudices that do not stand up to scientific scrutiny.
And since these prejudices are reinforced by their qualifications they are given the stamp of authority.
They are repeated daily in clinics, gyms and surgeries around the world to millions and millions of people.
Repitition does not make for validity.
We are the first to look at fat metabolism from the perspective of the liver/brain axis with respect to weight control and to focus on recovery biology and how it may be optimised.
The book was written for the popular market, but each and avery principle is sourced from the existing scientific literature.
We simply noticed what everyone else had missed.
Here is how the process works.
The connection between insulin and sleep is well known, which is why we are often sleepy after a large meal.
Insulin drives tryptophan into the brain and tryptophan convert to serotonin.
Serotonin converts to mealtonin and this hormone actvates sleep in the dark.
Now of you take honey prior to bed the honey refuels the liver optimally due to the 1:1 ratio of fructose/glucose.
Some of the glucose will escape the liver circulation and provide a mild glucose spike, which will provoke a mild insulin spike, therefore preparing the body for sleep, via serotonin and melatonin.
Now production of insulin at night is not great because blood glucose would fall if the insulin was sustained.
I wondered at what the effect of melatonin would be and surprise, surprise, mealtonin inhibits insulin, thus protecting blood glucose stability during the night fast.

Melatonin inhibits insulin secretion and decreases PKA levels without interfering with glucose metabolism in rat pancreatic islets

Melatonin completes the cycle.
There is more.
Melatonin promotes production of human growth hormone (hGH) and this is one of the key fat burning recovery hormones.
Only if you view this biology from the perspective of the liver/brain axis at night would you notice these simple biological principles and be aware of their significance.
If you produced honey and put on the label:
'Honey promotes Sleep' and 'Honey Burns Fat' you would have the Advertising Standards people breaking down your door but the science is there to prove it.
I noticed this Honey,Insulin,Melatonin (HIM) Cycle only after the book was published.
