You seem defensive. Don't you believe it's better to be physically fit and energetic than not, or do you argue that fitness and health is truly irrelevant to your role as an employee?

You could suppose that there is an unfair cognitive bias at work (see /beauty premium/) which could favor one candidate over the other. But think about how an interviewer would consider the physically fit you versus the physically unfit you. This is the real point, not how you compare to someone else.
