I can only say that the principle of losing weight is to absorb less calories than to consume. According to the propaganda, the goal of losing weight is to reduce your energy intake and absorption at dinner. It's hard to say whether you can lose weight. After all, your energy intake has decreased (if you don't eat, you will definitely eat less), but what he said can provide a feeling of fullness. It is estimated that there will be a lot of sugar in it, because sugar can provide satiety in a unit volume, and correspondingly, the calories provided by sugar are also considerable (as is fructose).

It is not good to eat these things at present. He said it was to extract the essence of fruit. The key is what the essence is, it is all chemically extracted things, and a lot of nutrients are lost. Moreover, even if you eat whole fruit, there is no loss of nutrients, and nutrients such as meat and vegetables cannot be completely replaced by fruits.

In the final analysis, to lose weight, it is necessary to have a reasonable and healthy diet and moderate exercise. It's hard to say whether this kind of thing can be reduced. If it is reduced, it will be easy to be malnourished and weak.
