ELI5: How do movies deal with casting overweight and ugly people?

There are so many times in movies in which characters make fun of other characters for being overweight, but do they look for people who are initially fat to do the character? How are the characters okay with just being berated?

They put out a casting call for "big" or "unconventional" types.  The actor knows they are going for the ugly role but also they will get paid decently.  

Plus, the fat/ugly character is usually made up and costumed especially unflattering so the actor can take solace in the fact that they don't actually look as bad as the character does on-screen.
