Food issues, plus...

I will be doing some gaurdianship care for an 11 year old boy who was adopted internationally four years ago. (Yes, I found something that's going to work out!)Without going into much detail, he comes from a very abusive and poverty-stricken background, experienced a great deal of health issues due to serious malnutrition, was moved several times in his country, and was brought to the US speaking no English.One of the biggest issues that he faces in his current home has to deal with food, which is really no surprise. He does a lot of stealing food at home and at stores. From what I know he doesn't hoard food as much as he just takes anything and everything and eats it whenever he wants, even food that he knows is for a certain purpose or belongs to someone else.Also it's felt that he has a lot of "control" issues, again not surprising given his past, a lot of it has to do with not doing chores or school work, as well as pestering other kids relentlessly (not aggressively but just being in someone's face and picking on them, breaking their toys, telling stories about them, etc) nonstop.The last issue is one I don't really expect to have to deal with too much, and that's his opposition to his adopted father, which he himself has acknowledged that his birth father was very bad and therefore he doesn't want a father. He's bonded with his adoptive mom, and as a single mother I think he should be okay with me.I'm just looking for somethings to set into place prior to him coming into my home, to make dealing with these issues a bit easier, especially the food issues. I want to have clear expectations for him, but don't want to set him up to "fail", so to speak. Strategies that have worked for others, as well as things that seem to do more harm than good, are welcome. For instance I know that in the past he was denied snacks or even a meal (rarely) as a result of bad behavior, and I think given his situation, that probably only makes matters worse! Also, I want to give him some areas in which he has control and can be in charge of so that he feels he has a little control. For instance, what he calls me and how he refers to my family is his choice. He is welcome to call me by my name, mom, auntie or "Tia" among other things. Also, while he obviously has to use his legal name on school forms, etc, I want to give him the choice of what we call him here and at school - his current name, his birth name, a new name, whatever he wants. I want him to feel empowered in some areas!Lastly I want to give my own kids some ideas of how they can handle certain situations easily and in a way that doesn't aggravate things when they are having issues with him (or he with them).I appreciate your thoughts!ETA I should note that the adoptive family feels there was some "bad" information about him given (whether purposefully or not) and that he is likely 2 - 3 years older than they were told.
