Eating plans, dinner and crunches

I've set out an eating plan.

Every morning I will have oats, with non-fat youghurt and boyenberries with a cup of green tea(277cal)

then for lunch I'll have a scrambled egg(74cal)

But dinner is tricky. I'm expected to eat with the rest of the family, but because I don't cook (I don't know how) i have no control over what is being served so I don't know how many calories are lurking in my dinner. I suppose I could just eat all my vegies first, then as I begin to eat the meaty part i'll say I'm too full. or I could ake ages eating and everyone will finish before me, so then i could just throw everything away.

After every meal I will do 100 crunches, no exceptions!

This is it, i'm getting skinny NOW!
