Muscle consumes more glucose than usual in manual labor, and brain cells consume more glucose in mental labor. Eating less and eating more meals can continuously increase the glucose content in the blood, while the normal three meals can increase the blood sugar content three times. Glucose stored in the body can be released when needed.
When you are exhausted or haven't eaten for hours, the body will automatically release stored glucose, that is, glycogen in the liver and muscles. When glycogen content is low, the body begins to break down fat and protein, because they will stand up and break down into glucose when necessary.
The coordination of human body depends entirely on the precise interaction between glucose, glycogen and insulin. The concentration of insulin determines the amount of glycogen released, and the insulin level depends on the blood sugar concentration in the body.
It should be a wise way to understand how the brain and muscles maintain normal daily activities and ensure the stability of blood sugar level without using internal reserves.
If you are engaged in a job with high energy consumption, or you are a mental worker for a long time, a regular high-carbohydrate diet can continuously provide calories for the human body and keep you in the best condition. This method is very useful. Keep the total calorie intake unchanged and divide the food into multiple portions. Regular diet can really maintain an effective supply of calories.
This is the real reason why people often hear that it is better to eat less and eat more, because such a diet can keep you in the best condition at all times, and of course it will keep you slim.
