That's a serious question, and deserves a serious answer. Granted, I may be a little flippant sometimes...
But actually, single, celibate, and sane is a great place to start off.
I'll suggest that you scour every mailer and newspaper you get/find to look for sales.
Something you like will be on sale. Generally for about 14% off.
Buy it. Lots of it. All you can afford.
Sucks to have to live on it until next paycheck, but payday, you can buy the next thing on sale and the first thing is mostly still stored and not eaten.
This doubles as a weight loss program, depending on your tastes and physiology, and the sales.
After a couple of years, you find that you are having to moves stacks of stuff that you bought on sale. And your grocery bill is about 20% less.
Never eat at a restaurant, they are scams, I know. I'm qualified to run one.
