I had a couple of time periods where it was difficult to eat. First was the couple of weeks after my surgery, and the second time began a week or two after my radiation began, and lasted for maybe 3-4 weeks. My diet was mostly liquid in nature. I drank a lot of high calorie milkshakes, with a multiple scoops of ice cream, a variety of fruits, chocolate, peanut butter, etc. Always added a scoop of whey protein powder.

I also own a juicer, so I'd often make myself a green juice to make sure I'm getting my veggies. I was also able to get some soups down, but I had to make sure they were smoothly blended.

The liquid diet left me craving carbohydrates, so I was pretty happy when I was able to introduce thin noodles & start eating more solid food again.
