When I don’t bring lunch to work, I get "Fast Food." Every restaurant has healthier options on the menu and/or the restaurant allows the customer to remove unhealthy ingredients.
You control what is delivered to your office or your table. If you eat out, eat out as well as you can. If you order wings, opt for a side salad instead of fries.
Rule of thumb: add vegetables to every order and eat your vegetables first or contemporaneously.
