Doctors advise diabetics to keep their blood sugar levels below 10 mmol/l because otherwise they could go blind.
The strange thing about this is that it has been known for over 100 years that muscles use sugar as fuel. The more muscles that are active, the higher the blood sugar level.
Patients would have noticed this decades ago, were it not for the fact that the Contour, the device used by most patients to measure their sugar, consists of seven parts. This makes it completely impossible to take a sugar measurement while walking, running, cycling, or engaging in any other activity.

For nearly ten years, a select group of patients has had access to a sugar sensor. This is a device that is attached to your arm and measures your sugar 24/7, recording it in a graph. Doctors tell patients that the graph is chaotic, but if you compare the graph with your activities, a very clear line becomes visible.
- Blood sugar levels rise to 12 mmol/l when you have a bowel movement, pick something up from the ground, or prepare your breakfast.
- Blood sugar levels rise to 16 mmol/l when you cycle with a tailwind.
- Blood sugar levels rise to 22 mmol/l when you cycle against the wind.
- Blood sugar levels rise to higher than 28 mmol/l (the maximum measurement range) when you do the exercises in my exercise schedule.
Yet I haven’t gone blind. How is that possible?
My theory is that Adenosine triphosphate (ATP) protects capillaries against sugar.
When obese people train their oblique abdominal muscles, they gain more energy and, in their eyes, the accommodation muscles start working better.
In obese people, the feet are often turned outwards. When obese people train their calf muscles without also training their oblique abdominal muscles, their feet turn forward again, turn into blocks of ice, and in my opinion, there is a high risk of foot amputation. Doctors believe that the increased risk of foot amputation is linked to type 2 diabetes.
According to an article in this newspaper https://www.volkskrant.nl/ in the 1980s, a mutation occurred five million years ago that rendered our ancestors’ bodies no longer capable of producing vitamin C, forcing them to start eating plants, whereas they had been carnivores until then. All apes living on Earth today are descended from this mutation.
Plants contain much more sugar. According to doctors, sugars are extremely bad for capillaries, particularly those in the retina. Therefore, it is inevitable that a second mutation occurred within a few days/weeks/months/years that solved the sugar problem. Otherwise, our ancestors would have become blind and gone extinct.
My theory is that the back door of the oblique abdominal muscles was opened. All muscles are capable of converting sugar into a limited supply of ATP. But if it becomes possible to deposit that ATP into the bloodstream, then it becomes possible to process a virtually infinite amount of sugar.
ATP in the bloodstream meant that our ancestors had access to much more energy. For example, the leg muscles are unable to extract more sugar from the bloodstream than was available before the mutation five million years ago. However, they are capable of extracting extra ATP from the bloodstream. When you ride a bicycle without gears, your leg muscles need this extra ATP to move forward.
The functioning of the oblique abdominal muscles is the difference between apes and humans.
Muscles without ATP production
Evolution builds upon existing systems. With ATP in the bloodstream, it proved possible to develop muscles that do not produce their own ATP. These muscles turn out to have major advantages. When you lie in bed for three months, you have to learn to walk again because your leg muscles have become weak. But when the accommodation muscles receive ATP again after thirty years, they immediately become active again.
I think our ancestors discovered the roll-up about 4.5 million years ago. For thin people, the roll-up is the easiest way to get back up when lying on their backs. After half a million years, the first three parts of the rectus abdominis muscles would have become much heavier, allowing them to increase their walking speed from 2.9 km/h to 6 km/h. The first three parts of the rectus abdominis muscles consist of 80% muscle cells that do not produce their own ATP, which is the reason why it is so difficult to train them. You have to train the oblique abdominal muscles first because they are the ones that supply the ATP.
About 2.5 million years ago, another development occurred. While our ancestors walked, their center of gravity was located in front of their lower legs, causing the hands on their hind legs to be loaded. This stimulated the development of elongated feet. With elongated feet, the body’s energy consumption at 15 km/h is approximately equal to the energy consumption at 8 km/h. This allowed our ancestors to increase their maximum speed. The elongated feet consist of 90% muscles without their own ATP production. Therefore, the body needed extra ATP production capacity. The calf muscles also deposit ATP into the bloodstream.
The growth spurt originated approximately 1.5 million years ago.
Accommodation muscles developed approximately one million years ago. At a speed of 15 km/h, you can reach the horizon within 20 minutes. This means that large grazing animals on the horizon became a realistic prey. This means that we needed better eyesight. Accommodation muscles are entirely new and consist of 100% muscle cells without their own ATP production. So, if the oblique abdominal muscles and calf muscles become weak, you become nearsighted.
Cold feet
Humans have a reflex. When the front half of the sole of the foot is subjected to extra load, all four parts of the rectus abdominis muscles are automatically tensed. This has advantages for natural running. There is a cardio exercise where you place your toes on the pedals and cycle at high resistance to the rhythm of music. By placing your toes on the pedals, you train your calf muscles, which triggers ATP production and causes your feet to rotate forward. The feet need this ATP to perform the walking motion.
When your car runs out of fuel, it stands still. I have the strong impression that the weakening of muscles with their own ATP production is due to the fuel running out.
To produce ATP, the muscle must actively pump phosphorus molecules from the bloodstream into the cell. This requires energy. So, when the muscle is active, it uses something like 95% of the available energy to contract the muscle and 5% to pump phosphorus molecules in. But if a muscle is used too little, for example because you have to stay in bed for a few months, then 100% of the remaining energy is used to contract the muscle. As a result, no energy remains to pump phosphorus molecules inward, and the supply of ATP molecules slowly runs out.
After the first three parts of the rectus abdominis muscles have been sabotaged, the fourth part is hardly used anymore; you use it a little bit when walking. This causes the supply of ATP molecules to slowly run out.
When you activate the rectus abdominis muscles using the cardio exercise, the fourth part begins to replenish its supply of ATP molecules. In doing so, it strongly appears that it is easier for the fourth part to siphon off phosphorus molecules from the ATP molecules in the bloodstream than to actively extract phosphorus molecules from the bloodstream itself.
As a result, the ATP molecules produced by the calf muscles, which are actually intended for the feet, are sabotaged. Consequently, the energy supply to the bloodstream of your feet stagnates. You feel as if your feet are turning into blocks of ice. Your feet’s sweat production stagnates and the skin on your feet turns white while cracks appear in your skin.
I don’t know what happens next, because that was the moment I discovered the oblique abdominal exercise and my feet started warming up again.
I mention the exercise that caused cold feet in my schedule. For the sake of completeness.
Diabetes 2
In my opinion, the problem with type 2 diabetes is not that the sugar gets too high, but that the body reacts too slowly. If you start an activity at 2 p.m. this afternoon where your sugar rises to 20 mmol/l, then your sugar should be at 20 mmol/l by 2 p.m. tomorrow afternoon so that your muscles have sufficient fuel immediately. But for diabetics, it takes three weeks for the sugar level to rise.
When you stop an activity after a few months or years, it is no longer necessary for your body to raise the sugar level at the start of that activity. It seems to me that the body should break down the sugar within a few days. But for diabetics, that can take as long as six months. The liver is capable of converting fat into sugar, but this process naturally requires energy. It is a waste of that energy to produce sugar for an activity that has not been performed for months.
Moreover, type 2 diabetes only occurs in people who have weak oblique abdominal and calf muscles, causing ATP production to stagnate. This means that problems with their capillaries can arise.
In my opinion, type 2 diabetes is diagnosed in people with weak oblique abdominal and calf muscles who suddenly stop an activity they have performed for longer than three weeks. Because the body continues to prepare sugar for an activity that is no longer performed for another six months, the average blood sugar level rises.
When you combine diabetes medication with training your oblique or calf muscles, problems can occur. I am not a doctor, so I cannot give advice on what you should do about this.
