Disadvantages of low-carbon water diet
In a short time, especially in 1-2 weeks, glycogen in the body is completely consumed due to strict restriction of carbohydrate intake. It can cause dizziness and weakness. The energy of brain activity mainly comes from blood sugar supply. When there is no blood sugar supply in the body, it can only be provided by decomposing fat or protein. At this time, physiological ketosis (nausea, fatigue, rotten apple smell, etc. ) will happen. Constipation, long-term intake of only a very small amount of carbohydrates, lack of dietary fiber in food to stimulate the intestines, constipation will accompany the whole diet process.
In the long run, a high-protein diet will increase the burden on the kidneys, especially for patients with chronic kidney disease. Long-term intake of red meat (lean pork, beef, mutton, etc.) rich in protein. ) will also increase the risk of colon cancer and rectal cancer. Long-term lack of blood sugar and energy supply may make the brain memory decline and even become stupid. The brain accounts for 2% of our body weight, but it needs 20% of the total calories every day. It is very picky and needs a continuous blood sugar supply. Only when carbohydrates are extremely scarce will the brain use fat or protein as fuel.
Therefore, our body cannot do without carbohydrates, which are the main source of calories for metabolism. A low-carbon water diet is not suitable for everyone.
What is a low-carbohydrate diet?
A typical low-carbohydrate diet usually refers to a low-carbohydrate food or a diet with limited carbohydrate intake. This diet is low in carbohydrates, while protein is high in carbohydrates. Usually eat meat, fish, eggs, nuts, seeds, vegetables, fruits and healthy fats. Try to reduce the intake of foods with high carbohydrate content, such as grains, potatoes, sugary drinks and junk food. The intake of low-carbon water diet is determined according to personal goals and personal preferences. Generally, the intake of low-carbon water is maintained at 50- 100g, which requires a lot of fruits and vegetables to maintain weight slowly and steadily.
Low-carbon water diet can lose weight in a short time.
Without carbohydrates, protein and fat, the human body can't function. For thousands of years, carbohydrates have been a great energy supplier. Today, the energy supply ratio of carbohydrates is still as high as 60%-70%.
The so-called low-carbon water diet is to limit the intake of carbohydrates. The energy supply of glucose is reduced or even disappeared, and the human body is equivalent to entering a state of hunger. When the body is cheated, it will change the energy supply mechanism, no longer consume glucose, but use the accumulated fat in the body to provide energy. In this way, the purpose of losing weight is naturally achieved.
At the same time, low-carbon water and low-carbon water diet encourage eating more fat. The satiety of fat is much higher than that of carbohydrates, and people who take fat as their staple food will reduce their desire to eat and eat less. The daily intake of calories decreases, and the rate of body fat accumulation naturally decreases.
Who is the low-carbon water diet suitable for?
Low-carbon water diet is characterized by rapid weight loss in a short time, which is suitable for people who need temporary rapid weight loss. Focus on weight, not body fat. However, people with hypoglycemia, pregnant women and lactating women, and people with liver and renal insufficiency should use it with caution.
As mentioned above, for ordinary dieters, a low-carbon water diet is completely unnecessary. Because in the long run, there is no advantage compared with a healthy low-fat diet. Moreover, after returning from a low-carbon water diet to a normal diet, unless it is kept low-carbon, it is easy to rebound. In addition, the low-carbon water diet has many disadvantages, such as hypoglycemia, constipation and malnutrition.
For fitness enthusiasts, low-carbon water diet is not recommended unless there are special circumstances. First of all, carbohydrates are the main energy source of moderate and high intensity exercise, and a low-carbon water diet is bound to reduce the storage of glycogen in muscles, thus affecting the training state. In addition, low-carbon water diet is easy to lose muscle. Life and work will be affected under hypoglycemia.
