"If you are what you eat, how many mushrooms do I…

Jean Anthelme Brillat-Savarin (1755-1826), in the book Physiologie du Gout (1825), wrote “Tell me what you eat, and I shall tell you what you are,” often interpreted as “you are what you eat.” This was figurative and not meant literally; one does not become an apple or a donut or a “skinny person” by eating such things.

“If you are what you eat then I am going to eat mushrooms because I want to be a fun guy. #imadork” was posted on Twitter by Greg & Jana Fletcher on April 3, 2012. “If you are what you eat, how many mushrooms do I have to eat to be a fun guy?” was posted on Reddit—Shittyaskscience on May 15, 2014. “Momma always told me ‘you are what you eat!’ So I started eating mushrooms every day. I wanted to become a fun guy” was posted on Reddit—Dadjokes on January 6, 2021.

“Why did the mushroom go to the party?”/“Because he was a fun-gi” is a related joke.

Wikipedia: Mushroom
A mushroom (or toadstool) is the fleshy, spore-bearing fruiting body of a fungus, typically produced above ground on soil or on its food source. The standard for the name “mushroom” is the cultivated white button mushroom, Agaricus bisporus; hence the word “mushroom” is most often applied to those fungi (Basidiomycota, Agaricomycetes) that have a stem (stipe), a cap (pileus), and gills (lamellae, sing. lamella) or pores on the underside of the cap. These pores or gills produce microscopic spores that help the fungus spread across the ground or its occupant surface.

“Mushroom” describes a variety of gilled fungi, with or without stems, and the term is used even more generally, to describe both the fleshy fruiting bodies of some Ascomycota and the woody or leathery fruiting bodies of some Basidiomycota, depending upon the context of the word.

You know what they say “you are what you eat” so I guess that means I’m not a “fun guy” because I don’t ever eat mushrooms.

If you are what you eat, how many mushrooms do I have to eat to be a fun guy?
I’ve eaten a quarter already, and I’m still me.
