i have lost about a stone (11.5 - 10.5) in less than a year. i find i need to eat 5 times a day. big porridge breakfast, fruit and yogurt at 10.30, sandwich and fruit at lunch, mid afternoon snack of a small sandwich and raisins. normal dinner.
if i eat protein at lunch (2 chicken breasts with some salad) i dont get too hungry till tea time.
my advice is add protein at lunch (fish/ chicken) and eat dinner at 7 - 7.30pm. this keeps the 9 oclock munchies at bay.
for me its the usual crappy processed food, sugary stuff and drink which is the killer for weight control, not the quantity of good food.
