It is called fasting. It has been practiced for entirety of human history in all societies except for last couple of decades.

Fasting is an opportunity for the body to burn stored fats. Insulin is a hormone that tells every cell in the body to take sugars from the bloodstream and effectively prevents burning stored fats. When cells are used to burning sugars all the time, when given access to sugars and fats they will chose sugars preferentially. So as long as they have supply of sugar there is very little fat burning happening.

What's more, when you stop eating for a moment, for whatever reason, your body still does not have ability to burn much fat for energy because the metabolic pathways to do it are too dormant to provide enough energy on a moments notice. You become hungry which is your body telling you it can't get energy and you resolve the only way to fix the issue is by putting more carbohydrate-rich food in your mouth.

Fasting periods are necessary for the body to train those metabolic pathways. For example, by eliminating breakfast and not snacking in the evening you can easily double the time it takes between two meals giving couple of hours each day during which your body has to get energy from the fats. Over time your body relearns to burn fats and when you don't eat for a moment for whatever reason it is able to start burning fats faster and start providing more energy lessening the feeling of hunger and immediate need to put more food in your mouth.

Fasting is the normal state of the human body. We have evolved in conditions where food was relatively scarce and when we finally caught something, we had to eat it here and now and then move on and wait until we are able to catch something else at unknown future time.

This means we have evolved to accept food for a relatively short portion of time, be very good at storing energy as fat and then to use this fat for a long time until we could catch something else.

Very interesting, thank you!

This correlates perfectly with my experience: When I've tried to incorporate breakfast or other frequent small meals into my diet, I've found it wreaks havoc on my energy levels and feeling of fullness throughout the day. Without attempting to "fast," I've found that I feel best and experience fewer "crashes" when I skip breakfast and after-dinner snacks. You've just explained a convincing reason why that would be the case.

Next level is removing most or all carbs from your diet and restricting your eating window to a short time every day, no more than 4 hours. Which is what I do besides longer fasts.

I now don't even need to eat every day -- I had situations where I skipped entire days of eating because I simply forgot about it.

If you think about it most people have hundreds of thousands of calories on them in form of a huge fat layer covering most of the body which is enough for even lean people to live off for weeks at a time. If you think about it, it is pretty silly to complain one is hungry when there is so much energy stored on us.

I remember this thought struck me when I was reading about first Inuits trading in Canadian outposts. They would sell their furs and buy food. When a curious scientist decided to follow them he discovered they would stop outside the outpost, eat ALL food they just bought in one huge binge and then travel back home for many days or even weeks without eating anything. They were not only good at storing fat, but they were also good at recovering the energy when they needed for however long they needed. This is what means to be fat adapted -- being able to completely separate intake of food from burning stored fat for energy.

People nowadays are like a car that does not have a tank for gas. You have to keep pouring the gasoline into the engine constantly or it will shut down. What you want is a large tank from which you can be constantly supplying energy to your engine but you can fill this tank at your convenience.

Yeah. But no. I naturally seem to eat once a day and am thoroughly overweight.

And this is meant to be proof of what exactly?

Somehow doing one thing right is supposed to prevent obesity in every single case?

That all obesity must necessarily be because of people eating multiple meals?

And you're not losing weight? What/how much are you eating?
