I just eat normal food in reasonable sized portions and try to avoid fast food, fried food and too many cakes and sweeties. I also avoid 'sports' and energy drinks like they were the plague.
Breakfasts: porridge with dried fruit, wholemeal toast with sardines or peanut butter or honey, low sugar cereal and/or muesli with semi skimmed milk.
Lunches: sandwiches and/or soup - the Baxters 'stay full' range is pretty good.
Dinners: hot pasta with sauces, cold pasta salads, stir fries with loads of veggies and brown rice, meat stews and/or casseroles with loads of veggies.
Snacks: bananas, apples, yoghurts, tinned fish, fruit ice lollies, kiddie sized chocolate bars and the occasional packet of crisps.
For me, watching my weight is all about portion size and controlling mindless snacking. If I feel peckish but I know it's just boredom and not real hunger, I have a cup of tea.
