# Why do nutrition provider activity events have null summary\_id?

Some nutrition-focused providers (for example, Nutracheck) do not supply a summary ID or accurate start/end times for workouts, so their activity payloads can contain null fields despite the general data model.

For these providers, the activity event type is being deprecated in favour of moving calorie information into the daily payload.

**Recommended approach:**

* Ignore activity events from these providers, or
* Sum calories at the day level.
