I've lived for many, many months on what people back home (US) spend on food per month. To do this, you might have to lower standards a little and increase the importance of having new experiences. If I wasn't struggling financially for various reasons, but making a very average "US office job" salary while abroad, I'd have lived like a king in the countries I've lived in. As is, I've lived in what I'd consider interesting locations and been in interesting situations, never at risk of going hungry but, frankly, always worried about it. In my early 30s, I'm now rethinking my lifestyle a bit but don't regret what I've lived.
