You can change the amount of an already-existing diary entry—without having to add the item again—as follows: 

1. Open your YAZIO Diary and click on your desired meal category.
2. Choose the Diary entry you would like to update.
3. Enter the new amount.
4. Click "Save".

Note: If you want to edit entries imported from other apps, you need to edit them in the respective third-party app, not in YAZIO.

We hope that you were able to find answers to all your questions and wish you a great journey with YAZIO.
