Mine is mixed. Didn't get much food at all with my mother, so I'd store and eat very little, but every now and then would pig out. This evened out a bit with my foster parents, although I'd say the damage was done as I was an older kid by then. And then I'd eat and eat unless someone told me to stop (and would even vomit from eating too much) and would keep food hidden under my bed, spend my money on longer lasting stuff so I could keep it (and all unhealthy type food too).
As an adult, I find it really hard to deal with leftovers. Instead of making it into another meal, I'll eat them then and there, because otherwise they might not be there tomorrow or whatever, even though I know that's not true. I can ignore signs that I'm full up and struggle to tell myself that if I feel full up, I should stop. I exercise a lot and always have, so weight isn't actually an issue for me, but I also tend to avoid particularly healthy food and even if I'm okay weight wise, what's going into my body isn't good and I have to work hard to keep it off.
I've started to write a food table, including a few snacks, which I can tick off and write in, so x number of meals/snacks a day, and I tick off my 7 fruit or veg a day, which has helped me to eat healthier. It also means I'm not eating the leftovers from the DC or whatever. I've also given myself a certain amount of money to spend on food, and when it's gone, it's gone. Of course, I could dig out some other money if I needed to, but it's helped me not to buy/store as much food (and therefore avoid temptation)
