Carbohydrate-free diet is a popular diet before, called ketogenic diet. Refers to the protein diet which is extremely low in carbohydrate, high in fat and moderate in quantity. It is believed that by simulating hunger in this way, biochemical and nervous system changes will occur in the body, so that weight can be reduced. In this mode, carbohydrate energy supply is about 4- 17%, fat accounts for 60-90%, and protein accounts for 6-35%, which is far lower than 50-65% in the normal balanced diet mode.

So is "not eating staple food" really a way to lose weight? We have to think carefully, because it is related to your health and figure!

According to the Dietary Guidelines for China Residents, the calorie intake of carbohydrates should account for 50%-65% of the total calorie intake in the whole day. It can be said that such an authoritative guide has already explained the importance of carbohydrates to the human body.

Only by eating reasonable carbohydrates can we maintain the energy consumption demand for one day. If the intake of carbohydrates suddenly drops to zero, then the body is prone to waterloo.

Let's first understand what carbohydrates are.

Carbohydrate is a compound composed of C\H\O H \ O. Glucose, sucrose, disaccharide and starch are all carbohydrates. In daily life, common carbohydrates are rice, noodles, grains and so on.

If you go on a zero-carbohydrate diet, it means that there must be no starch food in your stomach, so you can really lose weight, but this is caused by the lack of glycogen and water in your body, not the performance of losing a lot of fat.

Why not eat carbohydrates, instead of losing fat?

There are interactions among three essential nutrients (carbohydrate, protein and fat). When carbohydrate intake is insufficient, protein and fat will start to be consumed, and the consumption rate of fat is very slow. If you want to burn fat quickly, you must have the supply of carbohydrates as fuel to accelerate its consumption, otherwise you will only sacrifice protein, that is, muscle.

What's the harm of not eating carbohydrates for a long time?

1. Liver and kidney overdraft

Eating a lot of protein at ordinary times is good for shaping and growing muscles. However, without carbohydrate intake, protein's metabolism will have problems. Because the human body's ability to absorb protein and detoxify is limited, the "amino" in protein cannot be excreted through the urinary system, which puts great pressure on the liver and kidney.

2. Ketone poisoning

I believe some people also know that a long-term low-carbon diet can easily lead to ketosis. Because the body lacks starch intake, metabolism is prone to disorder. Once the body finds that there is a lack of sugar when burning fat, the incompletely burned fat will turn into ketoacid, causing bad breath and vomiting.

3. Memory loss

The operation of the brain depends on glucose to supply energy, so long-term lack of glucose intake, blood sugar can not be adjusted, the brain will be in a state of inhibition of activity, manifested as memory loss, emotional instability, easy to get angry.

4. Increase in weight

When your calorie intake is reduced by carbohydrates, your body's metabolism will gradually decline, your body's ability to store energy and water will decline, and your weight will drop in a short time.

However, once the normal diet is restored, the body cannot improve its metabolic capacity in a short time, so it is easy to store excess calories, produce fat and soar in weight.

So, how should we help lose weight while choosing the staple food?

The choice of staple food should be mainly coarse cereals, coarse cereals and complex carbohydrates, which are rich in vitamins, dietary fiber, plant alcohol and other substances, and carbohydrates are not easy to be converted into fat.

Then the staple foods you can refer to are: red beans, kidney beans, sorghum, brown rice, oats, black rice, corn, potatoes, potatoes and so on. And let the energy intake of carbohydrates account for about 30%-40% of the total energy intake.
