stress and appetite

just wondering if stress will affect appetite.
i heard ppl dun eat bcoz of stress but i found tat i hardly feel full or tend to look for food these few week.
eventhough i already had my normal meal.
just feel like eating
izzit bcoz of stress or just bcoz of the weather. it's turning cooler now.
try to control so tat i wont overeat n harm my stomach.
btw, sis, dun need to tell mum bout tis.. dun let her worry bout me. i m alrite here. living happily ever after... =p
