Lots of excellent support and advice here, so thank you :-D Ice lollies sound a good idea - could make them from fruit juice or nibble frozen berries. I am not going to buy any more biscuits. My OH loves my baking so I will bake flapjacks for him - I'm not that keen on them though so won't be tempted.
Walking after a main meal is an excellent idea but we tend to eat late in the evening, but I could run up and down stairs instead!
Jingl - rice cakes I have but had forgotten about them, so thanks for reminding me! Apples I've just got in and plan to eat those when in need of a snack.
We usually eat loads of veggies and salads, especially on fast days but other days too - except for yesterday's dinner which was extremely silly!
Must increase my efforts, drink more as advised, buy in celery, apples and cucumber to nibble on, eat smaller portions...tonight I'm making a chicken casserole with vegetables, and I plan to cook it with barley or quinoa if I can work out how, rather than with rice or potatoes (I love the latter so would eat too much of them)
Italiangirl - will try and look for that book. How was your fatty liver diagnosed and what do you do about it?
