Do Not Eat Back Every Calorie Your Watch Reports

Wearable energy estimates are useful trends, not precise permission slips.
Why this matters
The tempting shortcut is to treat one visible number, label, or feature as the whole decision. That makes a clean headline, but it hides the conditions that determine whether the conclusion travels to a different build, market, device, or person. The primary source below establishes the factual boundary; the recommendation here is an editorial interpretation of that boundary.
Use a repeatable check
Use body-weight trends, training performance, hunger, and adherence across several weeks instead of one device number. Record the date and source beside the result. If the underlying product, rule, filing, or guidance changes, update the conclusion rather than silently carrying the old answer forward.
What not to claim
Do not turn a feature into a guarantee, a scenario into a forecast, or one observation into a universal rule. Label estimates and judgments, preserve the assumptions, and give readers enough information to repeat the check themselves.
