Do workouts add calories to my day?

Activity does not add calories by default. If you choose Count activity from Health, Calsa shows the revised base goal before enabling it and adds half of the day's combined active energy from Apple Health or Health Connect. Protein does not change.

Calsa uses the platform's combined active-energy value, rather than adding steps and individual workouts on top of it. There is no manual workout logging. Check your phone connection and the activity line before assuming a missing workout should increase your food allowance.
