A Net Zero Diet

A old diet which could also be used nationwide for uninvited 'guests'.

 

I sat down on the spot, sir, and began to ponder: will a vagabond like that be very much trouble to me? And on thinking it over it seemed he would not be much trouble. He must be fed, I thought. Well, a bit of bread in the morning, and to make it go down better I’ll buy him an onion. At midday I should have to give him another bit of bread and an onion; and in the evening, onion again with kvass, with some more bread if he wanted it. And if some cabbage soup were to come our way, then we should both have had our fill.
