That wouldn't be enough food for me either I don't think.....

What I am eating at the moment:
Breakfast
1large breadmaker size slice (so probably 2 slices) grain bread with real butter OR
3/4 cup all bran/sultana bran
Sometimes a banana as well

Mid morning
Bunch grapes or pear or other piece of fruit

Lunch
Protein of some sort and vegies/salad of some sort
Sometimes a ham and salad sandwich on multigrain
Sometimes leftovers - so stirfry or chicken/salad
Small piece of fruit

Afternoon snack
Rice crackers/fruit/muesli bar

Dinner
Protein and vege/salad/rice - varies depending on the mood and what I've had during the day - ie if I've had bread, I won't have rice/pasta at dinner

After dinner sometimes have youghurt or fruit or a fruit pillow biscuit or something

Plus lots of water throughout day.
