Carbohydrate is the cheapest of the three main nutrients that provide heat energy for human body. Carbohydrates in food are divided into two categories: effective carbohydrates that can be absorbed and utilized, such as monosaccharides, disaccharides, polysaccharides and ineffective carbohydrates that people can't digest.
The main food sources of carbohydrates are:
Sugar and grains (such as rice, wheat, corn, barley, oats, sorghum, etc.). )
Fruits (such as sugar cane, melon, banana, grape, etc. )
Dried fruits, dried beans, root vegetables (such as carrots, potatoes, etc. )
First, carbohydrates are broken down into glycogen, which is stored in our muscles and liver.
Therefore, liver glycogen and muscle glycogen are waiting for our activities to consume.
Because when we do daily activities, or exercise training, or even shake our legs, we will decompose glycogen stored in our bodies as fuel to provide energy.
Therefore, a large part of the carbohydrates we usually consume will be converted into glycogen to fill the glycogen that has been consumed.
Under normal circumstances, but our body consumes too much glycogen, the "warehouse management" of glycogen will tell the brain: "I have enough here, please store the carbohydrates elsewhere", and then the excess carbohydrates will be converted into fat and stored.
However, it is not as easy as you think to convert carbohydrates into fat.
Because the carbohydrate we ingest is a priority as a supplementary source of glycogen, for example, when we ingest 100g of glycogen, the carbohydrate we ingest will be preferentially decomposed into 100g of sugar to fill our intake of 100g of glycogen, so we don't have to worry that the carbon water we ingest will immediately become fat and make us fat.
Important: Food will not be directly converted into fat.
Nutrients extracted from the food we eat will give priority to meeting the needs of our bodies, and excess nutrients will only be converted into fat when our bodies don't need them and stored for emergencies.
For example, if we use fat as coal and carbohydrates as firewood, then we can only burn coal if we burn the firewood. What if the firewood hasn't been burned? We'll turn the extra firewood into coal.
Even if we do consume a lot of carbohydrates, from energy supplement to massive oxidation to glycogen storage, this transformation process will waste some carbohydrates as the transformation price.
Glycogen likes carbohydrates very much, so it will oxidize more carbohydrates and store them for a period of time, so it is not easy to get fat.
So in general, if you occasionally eat too much carbohydrate, it is not easy to gain weight. Your weight will only increase because of the increase of glycogen storage, and it will not become fat, not fat, but will only bring benefits to weight loss and health.
Third, why did people in the past eat a lot of carbon water but not get fat?
This will start with the food eaten by the older generation. In the 1990s, the older generation basically needed a fixed amount of tickets to buy things. The carbohydrates they eat are basically mixed with coarse grains. Although there will be white flour, they are still relatively few, and they are not finely processed foods.
As far as we are concerned, the intake of carbohydrates is not the main reason for our obesity, while the dishes with carbohydrates are mainly high in oil and salt.
For example, the calorie of 100g rice is 1 16 calories, which is not high, but the calorie of a 250g bacon rice is basically around 900 calories, which is simply outrageous.
Including some fried rice and fried noodles we eat, are carbohydrates with high oil and salt, so we will consume a lot of calories, but after we gain weight, we will think that we gain weight because we eat too many carbohydrates.
