An inconclusive bit about eating + stress

Some ppl must eat when stressed and some ppl can't. Does it say how we handle stress? If eating builds energy reserve in those that binge for future defense (meaning those ppl are reactive) vs ppl who can't eat because food is inhibitive of a future fight. Meaning ppl who eat when stressed processed food faster into reserves while those that can't eat, process it too slow or can't store it.
