Ok, this makes sense.
Flipping it (comparing non-fasting to fasting), not only is the extra energy when not fasting used for functions other than health/longevity, but further energy is diverted away from health/longevity towards reproduction, because the best time to reproduce is when not fasting.
If the comparison were to starvation instead of fasting, some of the extra energy would be used for basic survival. But fasting is milder.
Is my understanding correct?
