How do you only eat once per day and not be starving all day?Nothing. I prefer to eat one meal in the evening, when I can relax and enjoy it. I voted $1-5 simply because there was no $0 option.
Your body and appetite both adapt. It seems impossible until you get used to it, then something clicks and you really stop missing food and spending so much energy thinking about it.
I'm curious about the inclusion of the "I bring lunch everyday" option? It's not like that food doesn't cost money. It could easily fit into the price range options. For example, there's a guy in my office that brings two frozen lunches every day. Each one is ~$3.50. So that's like $7/day, which is comparable to a fast food budget. Others that bring in leftovers are probably spending anywhere between $1-$4/meal. Seems to compromise data by lumping those two scenarios together.
Why would leftovers not be considered a proper meal? They were considered a proper meal the night before.About $10. I commute 2 hours a day like you, OP, and I try to go out with colleagues every day. Just getting outside and getting some fresh air is what keeps me going some days. Swedish lunch box culture is very strong but I refuse to be part of it. Why people who could easily afford a proper meal insists on constantly eating last night's leftovers for lunch will always be beyond me.
