How do I change a serving size once I've added a food to my diary?

In the app

1. Tap on the entry in your Diary and this will bring up a pop-up menu at the bottom of your screen.
2. Tap EDIT and select the correct serving size.
3. Select the meal occasion at the bottom of your screen and the details will be amended in your Diary.

On the website

1. Click on the serving size of the food when it is in your food diary (or calorie badge if using the Picture Diary view).
2. Change the quantity or serving size directly from your food diary.
