Brianna, I am sorry you are having to deal with what sounds like an non-supportive partner. You are correct, I cannot understand the food addiction aspects of the struggle. I have been eating healthy several years, and what caused my obesity was medication. However, I do understand the having to cook food for the family and them wanting fast food. And I can tell you what I have done in the past.
But first off, let me say your boyfriend's lack of support may be just lack of knowledge. My husband said the same thing a long time ago, why should I have to change because you are? And I said you are correct, you shouldn't "have to" and left it at that.
What I did was make meals that were healthier for me in terms of options, that is if I was making steak, potatoes, and a veggie, I would only eat steak and veggie, or make a killer salad to cut my steak over, or even eat part of a sweet potato. If they wanted fast food, I would go, order a burger with extra lettuce and no bun, or a taco salad no shell, etc. etc. Did you know that McDonald's has egg white? who knew, the things you find out just by asking. Not people will look crazy at you sometimes, but what the hell.
What happened with my family is they would see all these great looking things they wanted to try that I was making for myself. Like the loaded salad, or even the Greek yogurt, or spaghetti made with spaghetti squash rather than noodle, or the Pasta or rice dishes that I subbed with cauliflower. Slowly over time, things changed. They were ogling my food, and requesting that I make more of that. My husband finally said it made him feel left out when I would get so involved with making my own food, despite we were all sitting at the table. He then told me to just make everyone's food the way I make mine, and I did. Granted I still bake Desserts and give them the other stuff from time to time, but it was a fairly smooth transition. Years later, him and the kids don't remember when they started eating Greek yogurt, or drinking 2 percent milk, or cottage cheese with fruit in it. They don't know why they request spaghetti squash spaghetti or mashed cauliflower. And nobody is upset that some of the ingredients are sugar free or fat free or all natural.
I say all of that to say that sometimes for those on the outside, being supportive for something like this is very new, and you have to move forward regardless. There are thousands of recipes for making healthy, delicious options out there. And many restaurants have healthier options or foods which you can transform by taking something out. Make this work for you.
