If you want to quickly add the BITES for an item or meal that you already know the BITES value of, you can do a quick add. From your Tracker, tap the Add ("+") button located on the bottom of your tracking screen, select Food, then the blue pencil near the top right on the Results tab. This will take you to Create Food.

Enter a name for your food and then scroll down to the Override Bites section and enter in the BITES by tapping on OVERRIDE BITES VALUES. Tap on SAVE at the bottom. 

NOTE: If you track calories and/or macros as a Secondary Metric, not entering in calories and grams of protein, carbs, and fat will cause your Secondary Metrics to be inaccurate.
