Why do people develop type 2 diabetes?

Here, we will focus on #type_2_diabetes   (hereafter referred to as #diabetes ), but why do people develop diabetes?
There are many different opinions regarding diabetes, and I have no intention of dismissing them.
However, the reality is that people with type 2 diabetes have something in  #common_before_they_develop_diabetes :

People who develop diabetes have a lot in common

Commonalities

① Accelerated obesity
② Time spent isolated due to various reasons such as retirement or interpersonal relationships
③ Long hours spent sitting in a chair due to work
④ Onset of depression

In many cases, one or more of the above coincides, and it can be said that many people #spend_a_long_time_sitting .

On the other hand, a characteristic of type 2 diabetes is that symptoms ease when you adopt a lifestyle that stops you from sitting.

From this, you can see that there is a high correlation between the onset of diabetes and a sedentary lifestyle and obesity.

*This statistical survey is my own opinion.

Did you get diabetes because you ate sweets?

I don't deny this opinion.
But it's a little different from my research.
In my research, I'm of the opinion that people don't get diabetes because they ate (drank) sweets, but because they became diabetic and their body craved carbohydrates.
In other words, I think there was a reason why the body needed sugar.

So what kind of situations can cause the body to crave sugar?
First of all, the brain.
The brain is the organ that consumes the most sugar, so it's only natural that it craves sugar.
But did it suddenly need sugar?
There's a big question here.

Next, the body got cold, and sugar metabolism was necessary to relieve the cold.
In fact, I support this theory.

Human history has been a battle against hunger.
The era in which you can get anything you want if you have money, as is the case today, has only been around for the past few hundred years, but in order to get food, people have had to move to get it themselves.
The problem is what if you get hypoglycemia and can't move at that time?
Hypoglycemia can easily cause loss of consciousness.

If you become unable to move due to hypoglycemia when faced with some kind of prey, the prey will become you.
That would be inconvenient in itself.
For this reason, it is necessary to always be able to convert carbohydrates into energy and be in a state where you can start moving immediately.

In diabetes, hypothermia occurs in some parts of the body.
This can be the feet or hands, and the way to warm the feet or hands is by the command of hormones such as glucagon and cortisol, glucose, a type of sugar, is carried from the liver through the bloodstream.

Considering the above, it seems more natural to think that the body needed something sweet and tried to take in it.
Of course, I'm not denying differing opinions.
I'm just saying that if we think about it in a consistent way, we arrive at the results in this way.
