The reason for the lack of calories in Huawei's healthy diet record is: I forgot to punch in. You can do this:

1. Open Huawei Health APP.

2. Find and enter the "Diet Diary" at the top of the "Health" homepage.

3. In the "diet record" column, click the corresponding icon and fill in the food composition of breakfast, lunch, dinner and extra meals in turn.

4. When filling in, enter the name of the food in the top search field.

5. Then select the food weight, click OK to finish adding, and after adding all the food, finish punching in.

6. Back to the "Diet Diary" interface, you can see today's calorie budget.
