Suggest to add some quality fat to your diet. You can actual harm yourself if you're getting too many of your daily calories from protein. You need some carbs of course but if you overdo it then it's counter productive. So make up those additional calories with fats instead of carbs.

Olive oil and coconut oil are fine as long at they aren't heated ie. avoid deep fried foods like the plague. Animal fats are good for you so some nice marbled beef if you can get it. Or pork. Grass fed is always better than grain fed, but I realize that in a hotel you probably won't have that option.

Transfats AKA hydrogenated fats are fucking poison.

Soy oil should be avoided regardless because of its estrogen-like qualities.

You need some leafy green veggies with those rotisserie chickens (they are delicious, aren't they?). The human digestive track needs a certain amount of roughage to be healthy -- you don't want to be shitting rocks every day. Raisin bran will give you that, of course, but greens are better. Probably the best veg you can eat are onions. Have some ground beef with your chickens, too, and the occasional fish meal. You do have access to restaurants, right? Bread is always a staple of any healthy Western diet. I like buns, myself, rather than sliced. Put some real butter on them. And drink whole milk, not that evil 2% or 1% or skim. You need milk fat, which you get as cream mixed in with your 3% milk.
