Tired After Eating Means Low Body O2
Are you tired after eating? As we discussed before, night sleep is generally the most negative factor that reduces body-oxygen levels. The following most damaging factor is eating or meals, especially large ones. You can easily prove that eating dramatically reduces your body-oxygen content using a simple body-oxygen test (see the links below). It is a common effect that body-oxygen test results are reduced by up to 50% or 10 seconds due to ineffective breathing. Consequently, most people feel tired after eating. What is the mechanism?
Overeating produces a serious biochemical shock on the whole organism due to factors related to heavy breathing (or breathing more than the medical norm). Heavy breathing reduces CO2 in the blood and that causes constriction of blood vessels (see the image below) and the suppressed Bohr effect (less oxygen is released in tissues). Both effects lead to tissue hypoxia and feeling tired after eating.
Feeling exhaustion after eating and even getting drowsy and falling asleep after meals are typical signs of this biochemical shock. This effect of tiredness after eating lunch or other meals is much stronger after eating less nutritious food or junk food and especially overeating. We start to generate free radicals in body cells causing oxidative stress or damage to tissues, when the body-oxygen levels drop below 20 seconds.
People with normal breathing parameters (or with more than 40 seconds for the body-oxygen test) do not feel exhaustion after eating and can do light physical exercise, like walking or gardening, with no problems. Furthermore, normal breathing also means fast digestion or about 2 hours to digest a normal or regular meal.
The same meal for a sick individual (e.g., with about 15 seconds for less for the CP or the body oxygen test) usually require about 1-2 hours more to get digested. The sick person would usually need a rest after a meal.
Causes of fatigue after eating
The answer is simple: people used to have about 40-50 seconds for body O2. With such O2 levels, people crave physical exercise and do not feel tired after eating.
Feeling tired after eating, overbreathing and obesity
Why and how can hyperventilation cause obesity? According to Professor KP Buteyko, MD, PhD,
and research conducted by Russian medical doctors, CO2 is also responsible for
control of permeability membranes of fat cells. When we hyperventilate,
due to low CO2, glucose is driven from the blood into fat cells, and
the blood-glucose level naturally becomes low due to hyperventilation
alone. Since glucose is crucial for the brain and well-being, it
is sensible to eat in a manner that increases blood sugar levels up to
the norm. Eating more intensifies respiration and this leads to the
formation of a vicious circle:
- hyperventilation drives glucose into fat cells
- the person gets hungry
- he eats more and ...
- hyperventilates more.
Hence, over 70% of people "naturally" gain weight when they hyperventilate. And low brain and body-oxygen levels are the expected effects of overbreathing.
Conversely, when people start to slow down their breath while practicing reduced breathing (especially with the DIY breathing device or the Frolov device), they naturally have less hunger. If they start eating only when really hungry, they can easily lose weight. Physical exercise with only nasal breathing is another great way to fight obesity. These are the most natural methods or techniques to lose weight and increase body-oxygen levels. Moreover, breathing less makes obese people more alert and more energetic. All these factors make breathing retraining more meaningful than other weight loss techniques.
Permanent solution for feeling sleepy and tired after meals problem
You need to increase your brain and body-oxygen content up to 30 or more seconds so as to have much more energy and a clear mind 24/7. If you feel tired or sleepy after meals, this means that your current body oxygenation is less than 20 seconds, while the norm is about 40 seconds.
