This seems to come up every couple of weeks, and is invariably followed with a whole bunch of recipes for rice and beans. But the thing is that eating at McDonald's for three meals a day is both dumb and expensive. It isn't just expensive compared to rice and beans, it's expensive compared to regular-person food. A meal at McDonald's doesn't cost $3, it generally winds up more like $6... but even if you could find a way to eat at McDonald's for $9 per person per day, that's still a helluva lot of money compared to a sensible diet of breakfast cereal for breakfast, sandwiches for lunch, and meat + veges + rice/whatever for dinner.
