I see Brian Greene (theoretical physicist), Douglas Hofstadter (cognitive scientist and physicist), George Church (geneticist) and Christine Korsgaard (philosopher) on the list of vegans, although you could check if they were producing good work while vegan. I haven’t checked the list of vegetarians, but there are probably plenty of famous examples there. Edward Witten (Fields Medalist mathematical/theoretical physicist) is/was vegetarian.
There are also plenty of famous vegan artists and entrepreneurs, and their work often takes originality or novelty.
[just having a quick look at George Church]. Said there he’s “off and on vegan” which suggests to me that he was having difficulty getting it to work. But I checked his twitter and he said he was vegan as of 2018. He studies healthspan, so his voice counts. His page on his personal site unfortunately doesn’t discuss his approach to dieting or supplements but maybe he’d link something from someone else if someone asked.
