HOW WE’VE EVOLVED TO EAT FAT PREFERENTIALLY TO CARBS
Okay, let’s get straight to it. Your body actually prefers to burn fat over carbohydrates. There! I’ve said it. This is quite a nasty surprise for most people who still think that carbs should from the basis of a healthy diet – and that probably includes you.
I did too until a few years ago. But you’ve got to shift from this paradigm if you’re going to become a lifelong fat Burning Machine.
We humans have been hard-wired through evolution to prefer fat as the primary fuel source – both from a dietary, and storage perspective.
We’ve burned fat as the primary energy source throughout human evolution until the agricultural revolution 10,000 years ago.
The modern high-carb diet creates a dependency on external carbs (those that we eat) for energy at the expense of an efficient fat metabolism.
We’re always reliant upon a steady source of ingested calories for energy.
As we found out in Part 2, a high carb eating pattern stimulates chronic insulin production which locks away the abundant source of internal energy we have stored in fat cells.
This promotes a lifelong accumulation of excess body fat and emotional challenges – we’ve all had them – related to eating and balancing calories-in versus calories-out.
Since the metabolism of your stored fat has been inadvertently stopped by repeated high insulin producing meals, the major driver for energy becomes your next meal….
… this is not the case if you become fat-adapted….. but more on that shortly.
Breakfast’s the most important meal of the day, right? Don’t think so!
Most people consume a cereal- or grain-based start to the day, which has inevitable consequences.
That so-called healthy grain-based breakfast stimulates elevated blood insulin levels which lead to playing a blood-sugar balancing game throughout the day (ever wondered why you’re starving a couple of hours after eating your breakfast cereal?).
Let’s call it strategic snacking. It’s led to the conventional paradigm that we should eat every 2 to 3 hours to manage our blood sugar and energy levels. It’s more like a rollercoaster.
This perpetual carb dependency and regimented eating patterns can have a massive impact on our emotional relationship with food….
Does this ring any bells?
Our modern eating habits have created a massive disconnect with our natural appetite such that meals and food trigger a bunch of negative emotions and even an unhealthy obsession with eating habits.
Time for a change?
So what happens when we increase the fat intake and lower the carbohydrates?…
We ‘switch on’ the genes involved in metabolising stored and ingested fat, and….
Normalise appetite and hunger patterns.
Isn’t that exactly what you’ve been looking for?… to become a fat burning machine (i.l.o. fat storage machine)?
Transitioning from being a sugar-burner into a fat burning machine isn’t an overnight process, however.
You’ve been consuming an excessive amount of carbs from an early age, which has basically made you dependent on a regular supply of them.
Your body is conditioned to burning carbs as fuel instead of the stored fat. The result is that you crave the carbs more and more.
It leads to the perpetual cycle of weight gain through adulthood.
The good news is that you can change all that!
It is possible by eating the right foods to reset your body… the pros call it re-programming your genes – to its factory condition and become a fat burning machine.
Now here’s something that may come as a surprise to you. The body doesn’t actually even need dietary carbohydrate. Let me make that a little clearer…
You can live on ZERO carbs. Why?
Because your perfectly evolved body can manufacture glucose from fat and protein, and in amounts that’ll keep your brain in top shape and your energy levels stable.
There are NO insulin spikes here my friend. The pros believe that your body can produce up to 150 grams of glucose in any 24-hour period.
So who said you need regular meals to stabilise your blood sugar?
Now I’m not advocating a carb-free diet. I’m just trying to make a serious point.
If you choose to transform your body, you can selectively derive most of your energy from stored fat!
By allowing your body to provide its own source of glucose from ingested fats and protein.
For this to happen, you need to become fat-adapted… this means eating the right foods, along with reducing your carbohydrate intake.
By simply cutting out the excess grain-based carbs and replacing them with more desirable nutrient-dense carbs such as vegetables, your body will naturally arrive at an appropriate carb intake that minimises fat storage whilst setting you up for life as a fat burning machine.
Remember – fat and protein have been the dominant macronutrients for 2 million years. Carbs only got a look-in with the onset of the agricultural revolution 10,000 years ago.
This isn’t up for debate.
Our ancestors often went for days without food…. and this wasn’t through choice!
This lack of access to food and, in particular, a low carbohydrate intake led to efficient pathways to access body fat for energy.
This was the only way our species could survive day-to-day and generation-to-generation.
Our genes have not changed.
We’re still the same. We’re still programmed to rely on fat metabolism as our primary energy source……
… if we’re adapted to doing so!
Here’s something for you to think about as you get aligned with this new paradigm.
Our bodies have a ridiculously low storage capacity of glycogen – only 100 grams in the liver which is used for the brain and for other organs… this is less than a day’s worth.
Your muscles hold between 350 to 500 grams….. that’d be exhausted after only 90 minutes of exercise.
So if glucose was our ‘preferred’ fuel source and our ancestors have lived for 2 million years in a low carb environment how could we have ever have survived?
It’s just not possible.
But we have an unlimited fat storage potential.
Just look around you for the evidence.
Excess glycogen storage has been unnecessary because we have a tremendous capacity to store fat, to burn fat and to produce glucose internally.
Here’s a key takeaway for you….. limit your carb intake to between 50 and 100 grams per day and make up the difference with healthy fats and proteins, and you can hit the reset button on your factory settings!
It takes between 2 to 3 weeks for this transition to occur…. and that time is dependent on your current level of insulin-resistance.
And the end game? You become a lifelong fat burning machine.
