But how much protein is there in six glasses of juice? This is a bit tragic. The content of protein in fruits and vegetables is very low, with an average of no more than 1%. 1200ml fruit and vegetable juice can only provide 12g protein. This is far from the human body's daily demand of 60 grams of protein. Protein this kind of thing, no matter lose weight or not, must be supplied. Because we want to reduce body fat, not lose our internal organs, muscles, skin, hair, blood protein, immune protein and other useful body protein. Once protein is lacking for a long time, the human body will have symptoms such as flabby skin, fragile alopecia, low physical fitness, anemia, edema and decreased immunity. This is by no means the end that people who pursue health and beauty want to see.
Only drink 6 cups of fruit and vegetable juice, with little fat. The fat content in fruits and vegetables usually does not exceed 0.5%. Eating only 6 grams of fat a day is light, of course, but the essential fatty acids needed for body cell renewal can not be obtained, and the four fat-soluble vitamins of vitamin ADEK can not be fully absorbed. If nothing else, skin health cannot be guaranteed, and normal immune function cannot be maintained.
In addition, fruit and vegetable juice is rich in potassium, but calcium, iron and zinc are seriously insufficient; Both VC and folic acid exist, but vitamin B 1 is seriously insufficient, and vitamin B 12 is completely absent. These two vitamins are necessary for the normal work of the nervous system.
So seemingly fashionable fruit and vegetable juice can't be the staple food of the day. It can only be used as a supplement to the daily diet, and it is still possible to help people increase their intake of fruits and vegetables. Because westerners are not good at cooking and stewing, the intake of vegetables is often seriously insufficient and the varieties are not rich enough. Supplementing some mixed juice of fruits and vegetables every day, especially with dregs, is really good for your health. If only fruit and vegetable juice replaces three meals for many years, it will be miserable.
Another problem of fruit and vegetable juice is a serious lack of satiety, especially when you drink it without dregs. Our body's reaction to food is related to the state of food. Solid food causes great satiety and stays in the stomach for a long time; However, liquid food stays in the stomach for a short time and rarely causes satiety. Therefore, it is difficult for people to solve the problem of hunger after drinking fruit and vegetable juice. Although the stomach will become smaller and the appetite will decrease after drinking, after all, hunger can not be ruled out, nor can the blood sugar level be guaranteed to remain unchanged throughout the day. In contrast, eating fruits and vegetables directly, chewing with teeth and emptying slowly in the stomach will be more conducive to weight loss.
It is human nature and animal instinct to eat when you are hungry. Can Manager Pan only drink fruit and vegetable juice all his life? If he stops eating like this and goes back to a normal diet, will he regain his weight? This is predictable. Unless he changes his healthy diet, eats less oil and salt, polished rice and white flour and eats a lot of vegetables every day, he can maintain his weight. However, if you really change the wrong eating habits, even if you don't use fruit and vegetable juice to lose weight, you can still lose weight slowly without starving yourself for months.
In short, fruit and vegetable juice is not a long-term solution to lose weight, and healthy living habits can't be bypassed. Weight control is a lifelong career, not a short-term behavior. Who can only drink fruit and vegetable juice without eating vegetables all his life? Who wants to be hungry every day for the rest of his life?
