The human body is about 50%-60%, with more men than women. Water plays an irreplaceable role in human body. People who only lack water are more likely to die than those who only lack food. So from this point of view, water is indeed the most important component in the human body. People think that it is not important because water is very cheap and particularly easy to obtain.

Normal adults need about 2.7 3L of water every day. After deducting the water in food, they need to consume about 1.5- 1.7L every day. It is often heard that this disposable paper cup is about 200ml per cup, and 8 cups just meet this requirement. Pay attention to the water content of 1.5- 1.L, including the water content in milk, soybean milk, soup, tea, coffee and other beverages. If the ambient temperature is too high, or there is exercise, it is necessary to appropriately increase the amount of drinking water. In addition, the amount of drinking water can be appropriately increased or decreased according to the color of urine.

What's the difference between drinking water when you lose weight? Although there is no uniform standard, it is generally recommended that the daily drinking water should not be less than *30ml of body weight, that is, for a person of 60 kg, the drinking water should not be less than 1, 800 ml. Studies have shown that drinking water can slightly improve your metabolism 1 hour, so it is recommended to drink more water several times during weight loss. Hot water is better than cold water, so you don't need to follow any drinking plan.

(1) Honey water, if dry mouth and sore throat can't be relieved by drinking boiled water in the morning, you can try honey water, because honey is rich in fructose, which is very hydrophilic and has a good moisturizing effect on throat and gastrointestinal mucosa. Be sure to use honey that is not easy to crystallize, and it should be lighter, with a concentration of about 4%. However, if you want to relax with honey water, you must increase it.

(2) light salt water, many people like to drink light salt water to relieve constipation. The principle is similar to honey, but too little salt can't achieve the effect, and too much salt is bad for the health, especially for patients with hypertension, diabetes and kidney disease. If healthy people insist on drinking light salt water, they can drink 0. 1-0.2%, which generally won't have much impact. In addition, the total amount of salt per day should not exceed 6.9.

(3) lemonade. Lemonade contains a small amount of micronutrients such as citric acid, vitamin C, potassium, etc., which is beneficial to relieve the feeling of thirst and has a certain preventive effect on kidney calculi and gout. However, if the lemonade is too strong, it may cause stomach upset. Therefore, it is generally enough to add 2-3 slices of lemon to 1000ml of water. Without sugar, you can use hot water to soak, which has more nutrients. Drink after cooling.

(4) Finally, the most common boiled water is suitable for everyone to replenish water. It's best to heat it a little, about 40%. For weight loss, the effect is very good, but don't drink hot water above 60 degrees, which is not good for your health. If it exceeds 65 degrees, it will increase the risk of cancer.

The correct way to drink tea:

Tea is also a good diet drink, especially green tea, oolong tea and raw Pu 'er tea. Rich in tea polyphenols, it can reduce the absorption rate of sugar and fat, and has many health-care effects such as lowering blood fat, lowering blood pressure and bad cholesterol. So drinking tea for a long time has many benefits for weight loss and health.

However, the following points should be noted:

Secondly, people with malnutrition, children, pregnant women, wet nurses, iron deficiency anemia or anemia tendency are not suitable for drinking more tea;

Third, tea also contains caffeine, which can stimulate gastric acid secretion, promote gastrointestinal peristalsis and make people feel hungry more easily;

Fourth, drink less or no herbal tea.

Precautions for drinking coffee

Coffee is also good for losing weight. The beneficial components in coffee can regulate the metabolism of sugar and fat, increase the consumption of fat, regulate blood pressure, improve vascular function, and also have antioxidant and anti-inflammatory effects. In addition, caffeine in coffee is more abundant. Caffeine is a stimulant, which can improve exercise ability and increase fat consumption. Studies show that people who drink coffee every day will consume more fat than those who don't drink coffee, especially those who have exercise habits.

However, like tea, coffee also has a lot to pay attention to. First of all, the effect of hot coffee is obviously better than iced coffee. Then children, women during menstruation, pregnancy and lactation can't drink coffee. People with stomach problems, insomnia, heart problems and diarrhea should drink coffee in moderation. Remember not to drink espresso on an empty stomach. People with calcium deficiency and anemia should try to avoid the time of dinner when drinking coffee.
