The refreshing thing about these characters is that they never focused on their weight - they treated them like normal people. Being “overweight” isn’t Randy’s main/only characteristic. I’ve only seen one or two episodes of Roseanne (which ran for 7 seasons) that talked about losing weight and being healthy.

Sadly, now, any TV character over the size four (but under a size 18 because there’s no one on TV over that weight) is known as the “fat” character, where their character trait is FAT.
