First of all, we need to accept the fact that protein, carbohydrate and fat are just one element of the whole puzzle. There are many other things that affect our metabolism every second of the day. Let me highlight two other factors that play a crucial part in this whole system.

1. Autonomic nervous system

Basically, this is the part of your nervous system that you can’t control. It works in the background to keep you alive, so I think you agree that it is a good idea to support this system as much as you can. I would like to remind you that this is a very complex topic, and my aim here is to mainly help you understand the basics.

Firstly let’s see the parts of the autonomic nervous system. We have a Sympathetic side and a Parasympathetic side. What they do:

Sympathetic Parasympathetic
Dilation of pupils of the eyes Constricts of pupils of the eyes
Increases heart rate Decreases heart rate
Slows peristaltic action Increases peristaltic action

Most of the time one side is more dominant than the other, so we should strengthen the other side to create balance and harmony. This is crucial if you want your body to work optimally.

How to do that?
Let’s say you are an active person, who simply couldn’t sit in one place for 20 minutes, you talk fast, you are always about to do something, etc. In this case, your dominant side is probably the Sympathetic autonomic nervous system. It means, your meals should be based mainly on “good” carbohydrates (vegetables, quinoa, brown rice, etc). Of course, you need protein as well but not too much. Your fat intake should be minimal.

As I mentioned it is really difficult to recommend anything without knowing all the details and background of a person, so you really need to learn to listen to your own body!

Following the previous logic, if you generally are a calm, more introvert person, who like reading a nice book and you rather listen than talk, your dominant side is probably the Parasympathetic nervous system. So, you need a little bit more protein and “good” fat and you need to be a bit more careful with the carbohydrate intake.

2. Endocrine system

I guess you have already heard about the three main body types (ectomorph, mesomorph, endomorph). Now, let’s take a look at this topic from a different point of view. In 1965 Henry G. Bieler discovered that everyone has a dominant gland that plays a big role in metabolism and it affects not just the look of the body but the energy levels as well.

Which are the main glands that affect your metabolism?

1. Pituitary gland
If this gland is your dominant, you probably wake up early, your body looks “average”, you like sweets and caffeine and if you gain weight you develop ” baby fat” all around your body.

2. Adrenal gland
Usually these “type” looks strong even if they don’t train, they like red meat, they are “evening people” and if they gain weight it goes visibly to their stomach only.

3. Thyroid gland
Tall and thin people with long fingers. For them it is really difficult to develop big muscles due to this very active gland. However they need to be careful what they eat because they tend to think that they could eat anything without gaining fat. The risk of diabetes is the largest among this “type”.

4. Ovary gland
It affects only women. They have a dominant hip area with a relatively weak upper body (even if they are in good shape). They like strong spicy foods and fatty dairy products, and unfortunately they can develop cellulite easier than others.

So, why is it important to regenerate the dominant gland?
Let’s see a common example what happens if you have pituitary gland dominance.
Remember the first time in your life when you drank coffee. How did you feel? Happiness and more energy? It happened because you stimulated your pituitary gland and it started to work harder. The problem is that you will always want to feel the same “boost”, so you will need more and more caffeine. Unfortunately, after a while you will overload your gland and it will slow everything down in your body (no fat burning, no detoxification, no muscle building, etc).
So, if you want to keep your energy at the optimal level, you need to regenerate your dominant gland.

How to do that?

For approximately 21 days try to avoid foods that could overstimulate your dominant gland and try to follow the 5+1 rules I mentioned above.


If we want to summarize everything we need to understand that there are no magic pills or diets that work for everyone. You need to learn to listen to your body. It takes time and dedication but the rewards are worth it. And it is not just about a nice looking body, but about optimal energy during the day, better performance at work, reduced risk of injury and illness, better skin and so many other things.

Your food is your fuel. Use the best quality and the optimal variation your body requires.

There is no point to argue about how much protein, fat, carbohydrates do you need because it is individual (and if we want to be precise, it is quite outdated). It does matter where do these elements come from (vegetables, meat, fish, nuts, etc) and how they interact with other elements (organs, bones, tissues, other chemical elements, etc) but this is another complex topic that would drive us to the world of quantum biology.

So, in one sentence. 🙂

Try to follow the 5+1 recommended rules plus find out which is your dominant gland and side of your autonomic nervous system. Believe me, if you start eating a bit more consciously, you will notice amazing changes very shortly.
