About 25% of glycogen will be directly supplied to the brain for all activities of our brain. The rest will be transported to muscles and organs with blood.
Once the glycogen stored in our body is insufficient, our brain will feel threatened-sending a signal that "the baby is hungry and the baby needs to eat delicious food". If you still don't eat, your brain will get angry easily.
When our glycogen can no longer support the body's operation, then our body will accelerate the decomposition of fat. The role of fatty acids.
However, fatty acids are not the energy source that our brain needs, and because the complete oxidation of fatty acids requires the participation of sugar, without sugar, the body can only convert fatty acids into ketone bodies through "ketogenic reaction" to provide energy for the brain.
But at most, only 75% of the brain can function as a ketone body, and the remaining 25% still needs sugar. Lack of sugar can damage brain function. It is at this stage that it is easy to cause a series of metabolic disorders such as anorexia.
When the fat consumption reaches a certain level, about 72 hours (or 48 hours) after not eating, the body will start to decompose protein in its muscles and produce glucose through gluconeogenesis.
Slowly, the muscles gradually decrease, and the bodybuilding figure→ thin.
1-2 weeks later, due to the lack of vitamins and inorganic salts, our immune ability decreased and the function of the heart was also damaged. In order to survive, the body will further decompose decomposable tissues. Finally-space necessities (R.I.P Latin: rest in peace! )
Don't eat in order to lose weight (so-called don't eat after noon, don't eat the next day, etc. ) can basically be equivalent to repeating a certain stage above.
Moreover, once glycogen storage itself is insufficient (muscle glycogen storage will be less than normal exercise) or fat storage is insufficient (the kind of fat that you feel fat), the body will enter a state of stress earlier than expected.
Even Thor can become a bamboo pole. . .
Repeatedly, brain function is damaged, and habitual hunger strike will lead to a series of diseases such as anorexia and metabolic disorder.
You don't have to skip meals in order to lose weight.
Healthy weight loss really needs "diet control".
But "diet control" and "hunger strike". Diet control needs to be "fine-tuned" on the basis of the existing diet. Then through the accumulated diet improvement, correct the original unhealthy eating habits and gradually lose weight.
How to "diet control"?
First of all, diet control needs to gradually reduce the energy in the diet. For example, eating 3,000 calories a day has dropped to 2,500 calories. (You can estimate the energy intake of a day by combining food nutrition labels with Baidu. )
Secondly, diet control needs to improve the diet structure. Eating pizza, French fries, hamburgers and fried chicken every day will definitely not lose weight. But if you add more lean meat, vegetables, melons and whole grains to your diet, reduce your oil intake.
You will find that as time goes on, your figure will get better and better.
Finally, diet control needs to be adhered to. Rome wasn't built in a day. Diet control may not have any obvious effect for a week or two, but once you stick to it for a while, you will find yourself changing.
By the way, don't forget that regular exercise can not only reduce expenses (control diet), but also open up new sources (increase energy consumption). )
