I see, well if you are overeating that would mean you're eating more food than the energy you expend. Overeating will lead to weight gains and typically obesity.
I'm sorry! Sounds like you might struggle with overeating. Basically meaning that you eat an excess of food in relation to what you need.
When I am stressed, I overeat. Last night I ate a whole pizza by mself!
Overeating is the excess food in relation to the energy that an organism expends (or expels via excretion), leading to weight gaining  and often obesity.
