it sounds like you've done a good job on feeling better yourself, re: weight, so good work there.
However, to be honest i do have to agree with the others. It's not enough food, and you're setting up your kids to find self-worth in restricting their food intake to a degree that isn't healthy. You would be better off letting them eat more and insisting that they get an hour's running round per day (if they don't already) - and letting yourself eat more and getting 30 minutes' vigourous exercise per week. In your position (and given the possibility - I realise this may be impossible for all sorts of reasons) I'd add in snacks of fruit and veg and possibly toast, between meals, and a half-hour trip to the park every day to kick a ball around before or after school.
My mother was brought up with this kind of restriction of food in the house, with parents constantly harping on about the Depression, and has always had an incredibly unhealthy relationship with food, which she has passed on to my sister and my niece. My sister has an eating disorder (among many other issues). My niece will probably have an eating disorder soon if things go on the way they are. Everything is about being "good" by restricting food, and constantly running oneself down over body image.
I used to steal food because my mother was so restrictive. I had absolutely no self-regulation at events with free food, until I was in my mid-30s and realised I definitely needed to change my habits. I still absolutely crave sugary and fatty food, and if it's in the house I find it very difficult not to just eat it. These days I live in a different country from my family, eat healthily, do exercise, and honestly wouldn't really care if I weighed more than my mother and sister combined (I'd probably only be mildly overweight if I did). But every time I visit them, I am constantly criticized for what I eat, for the fact i'm not beautiful and underweight like my sister, etc., etc. and I return to the mentality of stealing food, buying food when I'm out of sight so that I can eat as little as I'm supposed to in front of mother and sister.
