fattest

Heaviest of all

Fattest is the superlative of fat—having the most body mass or bulk relative to others in a group: the fattest cat in the shelter, the fattest paycheck I've ever received.

Like fat, it extends beyond physical size to abundance or thickness: the fattest profit margins, the fattest part of the book.
