Best way for health and money, bring your own food and keep it chilled. I've brought my entire food for 4, sometimes 5 days. Get a fridge every night with a freezer for a good ice pack. Oatmeal, fruits vegetables all fresh none frozen. Low cal wraps for turkey, cheese and lettuce. If you don't get a good cool one night on the food it'll be fine maybe not till the end of the trip but thats happened very few times on me. You can tell if things go a little funky. Never have had food poisoning and always feel great. Done this for nearly a decade. Works great at the majors too when you do make more money and you have more to spend at home. As far as those saying the food is 4/5 days old, I'd eat the same thing at home...left overs cold cuts I buy for the week. Wouldn't change a thing. Add in some self made trail mix with cereal dried fruit; fuels me well. Saving on tips that someone brought up is also a great point.
