1. protein's intake must be sufficient. Eat not only vegetables, but also foods rich in protein, including beans, bean products (tofu, soybean milk, dried tofu, etc.) and dried fruits (including peanuts, but there are some things to pay attention to when eating dried fruits, which will be mentioned below).
You should take all kinds of vitamins. The simple and safe way is to take all vitamins and calcium tablets every day. The complicated way is to eat all kinds of vegetables. The only nutrient lacking in vegetarian diet is b 12. It used to be thought that vegetarian food such as kelp could provide b 12, but recent research found that b 12 in vegetarian food was very unstable. Therefore, vegetarians must take extra vitamin b 12 tablets. Otherwise, it may cause anemia or neurological problems after a long time.
It's a good idea to buy a weighing scale to monitor your weight when you are a vegetarian. Although vegetarian diet can lose weight, there are some misunderstandings, which will lead to weight gain if you don't pay attention. What are the misunderstandings:
A. Some people don't get enough protein, so they always feel hungry, and then eat a lot of meals, and as a result, they gain weight.
B. Although protein is rich in dried fruits, they are also high in fat, and if you eat too much, you will get fat.
C. Some people will become addicted to sugar or eat snacks after eating vegetarian food.
D. Some people drink too much milk-milk is high in fat, which will lead to weight gain. So if you want to drink milk, you'd better drink all skim milk. Or use soybean milk instead.
Of course, eating some fruits and vegetables and increasing fiber are good for your health.
