Jason, like you people are amazed at my appettite (and i'm lighter than you!):
breakfast - kiwi, porridge, 2 poached eggs on brown soda/seed bread, tea
11am - triple-decker oatcake/hummus, nuts, coffee
lunch - big salad, mackerel or similar, pitta bread
afternoon - apple, biscuit
dinner - fish/chicken + sweet potato/pasta + 3 veg, yoghurt and nuts, coffee plus the odd glass of red
10pm - 2 x weetabix, semi-skimmed milk
I run 4 times a week and like yourself have a seemingly quick metabolic rate. Would like to put on a few pounds but doesn't happen.
