It was a series, something like Spaceways Patrol or something. Kind of pulpy, maybe, around the 80s. Small books, maybe around 150 pages.
One of the books had some guy who was storing his fat outside of his body in cases maybe, and when they were lost (or stolen, or destroyed), he was upset because you only had so much and he couldn't get it back. I know there is more to that but it has been over 20 years since I've read it and can't remember a lot. I know some sort of space police were after him for some reason.
There were other books in the series (at least one more), and I don't think this was the first book. Maybe Interstellar Patrol instead of Spaceways?
Edit:. There is a series of stories collected in a book called Interstellar Patrol by Christopher Anvil, and there is a story called The Nitrocellulose Doormat, but I found that story online and it doesn't seem like what I'm thinking.
