I've had lifelong food dependency/bulimia issues.
My dad: he more or less ate pretty healthy. Not restrictive 'healthy' (re: diet) but he didn't eat butter or margarine or mayonnaise, didn't use salt, etc. He ate real food. But at dinnertime (we always ate dinner together as a family) he would eat everyone's leftovers (there were four of us kids) if there were any. He refused to see anything go to waste. He would save even water with weiners boiled in it to use as soup stock for himself, lol...I still bug him about that. I've seen him get really **** about it and actually take half-eaten fruit out of the garbage and wash it off and yell at the person who threw it away. He also used to fly into a rage if anyone threw anything out that he deemed inappropriate. For example, I remember one day my mom called and asked him to go to the restaurant and do something for her (this was toward the end of their marriage, when all they did was make each other miserable). He had just made a breakfast for himself of side bacon, eggs, etc, and was sitting down to eat when the phone rang. So he took off in a huff. While he was gone my brother ate half of it and picked the rest apart so I came along and threw it out. Well my dad came home and asked where his breakfast was and when I explained what happened he flew into a rage about how money doesn't grow on trees, yada yada. We ended up having a screaming match that ended with me going to the bank, taking out all the money he'd given me to help pay bills while I was waiting to get on medical EI (I was pregnant) and giving it back to him. Now, fast forward ten years, he and my stepmother have been on some weird-*** Atkins type diet where they don't eat any carbs or foods with any kind of high glycemic level. He cheats all the time whenever he travels, but that's how it is. I never thought I'd see my dad on a diet.
My mom: she was always slim until she had four kids. Then she filled out. One day when we were all still school-aged - I was probably in my teens, the youngest would have been still about 6 or so - she saw a picture of herself that caused her to become disgusted with her appearance, and she more or less stopped eating. She always was a chain smoker and drinker, and a compulsive Pepsi drinker, and a picky eater to boot. But it got to the point where she wasn't eating much of anything. She'd still make us all these really elaborate meals but not each much herself. By the time she bought the restaurant it was really obvious. She spent most of her time there and her idea of a meal was half a sandwich or a bowl of soup (as in, one or the other), or she'd just have a bite or two of what someone else was having. And she always used to make comments about my eating disorder, and about my brother's and dad's weights. Food and fat were definite issues for her. And ironically all three of my siblings have issues with disordered eating.
