## Frequently asked questions

### Can this hub tell me what diet or training plan to follow?

No. It provides educational calculations from the inputs you enter. It does not diagnose health conditions, prescribe nutrition, or replace a qualified professional.

### Why combine nutrition, body composition, hydration, walking, and sleep?

They often inform the same planning conversation: energy needs set the calorie range, macros and protein divide it, activity and sweat rate add session context, and sleep affects recovery timing.

### Should one calculator result override the others?

No. Treat each result as a separate estimate with its own formula and assumptions, then review the spread instead of forcing a single definitive answer.
