Pretty easy. Get fully cooked eggs from Whole Foods, pate, duck liver / pork liver / chicken liver mousse, or just buy ground beef and cook it at your apartment, Airbnb or home or place or residence. Or just hit up the hot food bar — 4 pounds of beef meat and beyond.

Also — for gym, just find local gyms and just rent a car, Uber there and either get day passes, week passes or even a month pass. Travel with your own liquid mini tube weight lifting chalk.
