First of all, it's not that you can't eat meat, but that you should eat less meat and choose meat with high protein and low fat. Meat is rich in protein, which is irreplaceable. In order to eat less meat, it is advisable to use tofu to partially replace meat.

Tofu and meat are both foods rich in protein, but tofu can only replace part of meat, but it can't completely replace meat. Because the protein content of many high-quality meats, such as chicken breast and fish, is much higher than that of tofu, it is necessary to ensure that the human body consumes enough protein for healthy weight loss. Under this premise, only eating tofu to consume enough protein will consume more calories than eating meat, which is not conducive to weight loss.

Moreover, the protein contained in meat belongs to animal protein, and the protein contained in tofu belongs to plant protein, which is more beneficial for human body to absorb than plant protein. Protein of human body is composed of 2 kinds of amino acids, of which 12 kinds are called non-essential amino acids which can be synthesized by human body through its own biochemical reaction, and 8 kinds of amino acids which cannot be synthesized by human body and must be provided by food are called essential amino acids. Animal proteins generally contain 8 kinds of amino acids which are essential to human body, while plant proteins contain few essential amino acids, especially lysine. So you can't just eat tofu without eating meat.

Moreover, meat also contains some trace elements and vitamins that tofu does not have, such as vitamin B12. These vitamins and trace elements are very important for maintaining health, so it is not recommended to completely replace meat with tofu during weight loss. And eating too much tofu is easy to cause indigestion, which is not conducive to health.

But in order to prevent excessive intake of meat, it is still possible to replace some meat with tofu. Although we should pay attention to diet control during weight loss, we still need to ensure full and comprehensive intake of nutrition. Eat less fried food, don't eat too much sugar and exercise more. Eating less, exercising more and persevering will naturally achieve the goal of losing weight.
