The Jane Austen Diet

I must be going on a diet (with the Chinese New Year feasts ahead) as I've been a shocking omnivore of late, eating any- and everything and unrepentantly remembering how, once upon a time, I would at various stretches not eat yolks, prawns, red meat, fishballs, luncheon meat. A decade went by without drinking sugary bottled drinks; Years went by without my eating cake. Now, sadly, I eat everthing like the Veronese boy (above, Boy Eating, Veronese). Durian, mango, claypot rice, birds nest, beef burger, carbonara pasta, lobster, tempura prawns, early pineapple tarts - all this within the last week.
Emma's Mr Woodhouse would not approve. Mr Woodhouse prefers plain cooking for invalids (or anyone, actually):
“Mrs. Bates, let me propose your venturing on one of these eggs. An egg boiled very soft is not unwholesome. Serle understands boiling an egg better than any body. I would not recommend an egg boiled by any body else — but you need not be afraid — they are very small, you see — one of our small eggs will not hurt you…"
Prescribed diet from Mrs Rundell's 1816 book, A New System of Domestic Cookery formed upon Principals of Economy:
1. Water Gruel
Put a large spoonful of oatmeal by degrees into a pint of water, and when smooth boil it. (You see, this is quite easy to make, but perhaps not very tasty.)
2. Eggs (click and see below)
