Just that really. I have been overweight all my life after a childhood of being rewarded with sweets and chocolate. This is a really hard habit for me to break. I have managed to break it for my children who both have healthy diets and are healthy weights although my DD has a fairly solid build so I imagine it wouldn't take much for her to put weight on. They go to a school which does lots of sport and they provide traditional school dinners, very old fashioned home cooking but they are served to the children using proper portion sizes. The children have very little choice, they are just given the meal of the day which works very well for my children as it has made them very unfussy eaters.
We need to change things at home. I have got into the habit of giving them a quick tea (crumpets with salad, beans on toast) and then DH and I eating crap later on in the evening. I desperately want to lose weight as I know I am a ticking time bomb. I have bad knees but luckily no high blood pressure or cholesterol as yet. I eat way too much chocolate and can consumes 4/5 bars a day sometimes 
I want to make a change over the summer when things are more relaxed but have no idea where to start. I need to make meals that are suitable for all of us but will help DH and I lose weight whilst giving the DC everything they need.
I am sadly in the low carb, low fat mindset from many years of failed dieting but now have the low sugar message too. I have no idea how to eat properly. My friend saw a Nutritionist who told her to eat red meat once a week, chicken twice a week, fish twice a week and the rest of her meals veggie. Is this correct? I have no idea.
Can anyone offer any advice? I would love to start meal planning. Are there any good websites for healthy weekly meal plans that don't use a billion ingredients?
