Challenging myself to live on minimum wage for one week... any tips/advice and how much $ do you live on per day?

I have about $10 to spend per day on food and other day-to-day purchases. The cost of rent/utilities has been factored out.

I'm doing this in conjunction with r/LiveTheWage (a community I started) which is apart of an effort based out of Cambridge, MA to raise the minimum wage.

All politics aside, I'd love to get your tips and advice to help me make it through the challenge. I'm also curious to know how much money you spend per day after rent and basic utilities.

EDIT: I'm considering only eating one meal per day. I heard about a guy Wim Hof who does this. He only eats around 6pm and fasts every day until then. Could be a great way to save cash.
