"McResource Line" — McDonald's' employee-only resource and advice site — has been dispensing a hot mess of helpful tips in recent months: From advising workers to get a second job, to suggesting they sell their stuff for quick cash, to reminding them to tip their nannies and pool boys generously this holiday season.

Its latest recommendation, however, may be its most useful yet: Lay off the fast food.

An image posted on the site labels a McDonald's-like meal of hamburger, fries, and a coke as an "unhealthy choice," and warns employees against consuming such foods, which are "almost always high in calories, fat, sugar, and salt."

"It is hard to eat a healthy diet when you eat at fast-food restaurants often," the site goes on to say. "Many foods are cooked with a lot of fat, even if they are not trans fats. Many fast-food restaurants do not offer any lower-fat foods. Large portions also make it easy to overeat. And most fast food restaurants do not offer many fresh fruits and vegetables."

So what can employees do to eat healthier? For one thing — stay away from McDonald's.

"In general," the site suggests, "eat at places that offer a variety of salads, soups, and vegetables."

In a statement to CNBC, McDonald's insisted the website's tips "continue to be taken entirely out of context."

None the less, the company said it was "looking into the matter."
