How do I change the theme, dates or nutrients shown in my diary?

Open You → Appearance to choose the system theme, light or dark appearance and the nutrients shown in the day's summary. Use You → Units and time for your supported date, time and unit preferences.

Changing the display does not change the underlying recorded food or convert a missing nutrient into zero. If you want to hide body or calorie numbers rather than change the theme, use You → Tracking. Check the diary after saving to make sure its display matches the choices you intended.
