Separate food intake from activity energy
When people ask how to track calories with Apple Health, they may mean recording food intake, viewing activity energy or connecting a nutrition app. Those are different tasks. Dietary energy describes calories eaten. Active energy describes energy used during activity. Seeing one does not establish that the other was recorded.
Keep the source and date of a record clear. A meal total in a calorie tracker and an activity number from a watch should not be treated as the same field or copied into each other.
Add a known food-energy entry manually
Apple's Health data instructions explain manual entry through a category's Add Data control. On iPhone, open Health, use Browse or category search to find Nutrition and Dietary Energy, then enter the relevant amount, date and time with Add Data. Labels and navigation can vary with your system language and version.
Use a total you can identify, such as a meal you already logged. Check the displayed energy unit before entering the number. A food calorie is normally expressed as a kilocalorie; do not copy a kilojoule value into a kilocalorie field without the appropriate conversion.
Keep meal entries distinct from a whole-day total. Entering both into the same day can double-count food intake. If you discover a duplicate, inspect the entries and remove the incorrect one using Health's data controls.
Check permissions and data sources
Health permissions are specific to an app and data category. An app being compatible with Health does not mean it writes every nutrition field. Inspect the application's Health permissions and the source list for the category you care about.
Apple's instructions describe viewing compatible apps through your Health profile and inspecting Data Sources & Access for a category. You may also need to check the connected app's own settings. If a food record is absent, determine whether the app supports writing that type before repeatedly reconnecting it.
What Heyberry currently supports
Heyberry's current Apple Health integration is read-only. With permission, it can read steps, active energy and body mass. It currently does not write dietary calories, protein, carbs or fat into Health. Logging a meal in Heyberry therefore does not automatically create a food-energy record in Apple Health.
You can keep your food diary in Heyberry and manually add an identified food-energy value to Health if you choose. That is a manual step, not an advertised automatic sync feature. Meal logging in Heyberry requires Pro; see pricing.
A short troubleshooting checklist
If you expect a food entry and cannot find it, first check that you are viewing Dietary Energy rather than an activity category. Check the day, displayed unit and contributing sources. Then confirm whether your nutrition app actually writes that category and whether its permission is enabled.
For Heyberry, the absence of dietary-energy export is the current capability boundary. Turning on read permission for active energy does not add food export. Our calorie counter app page explains the supported meal methods, and support covers account and data questions.
