In the eyes of many people, fruit and vegetable juice is the best way to lose weight, and many nutritionists often recommend it to people, saying that it can not only supplement vitamins, minerals and antioxidants, but also make people lose weight for a long time. But can fruit and vegetable juice really make you lose weight healthily? See what experts think about the fruit and vegetable juice diet. 1. Fruit and vegetable juice is good, but it can't be eaten for a long time. There is no need to eat only fruit and vegetable juice, because your stomach and digestive system are not poisonous, and you don't need to rest. Even if you do lose some weight through fruit and vegetable juice, a short-term low-calorie diet has disrupted your metabolism. Although drinking fruit and vegetable juice can supplement the body's sugar, but because it does not consume any carbohydrates to supplement energy, daily life will be very tired, and side effects such as acute stomach pain caused by juice are also very common. 2. Fruit and vegetable juice can easily lead to malnutrition. On the surface, fruit and vegetable juice does contain a lot of vitamins, but in fact, if you only drink juice squeezed from vegetables and fruits every day, you will miss the intake of many other nutrients, including calcium, protein, vitamin D and essential fatty acids. And because there is not enough fiber in the diet, constipation will cause headaches in a few days. 3. Long-term fruit and vegetable juice is prone to hair loss and aging. If you plan to drink fruit and vegetable juice for a few weeks, the problem of hair loss will come to you in about two or three months. This conclusion has been investigated by experts. They found that many women with hair loss often have the habit of frying and only drink fruit juice as food. In addition, if you don't eat other foods in fruit and vegetable juice every day, your skin will gradually become dry, because there is no basic fatty acid you need in the food. If it takes a long time, your skin will get eczema frequently. Don't listen to the magical effect of fruit and vegetable juice to lose weight. Although vegetables and fruits are high in amino acids, they are good for your health, but if you consume a lot of concentrated juice, it will damage the enamel of your teeth like carbonated drinks.
