Andrew Huberman has consumed foods with artificial sweeteners, including occasional Diet Coke, and uses stevia.

“I have long ingested foods with artificial sweeteners. So throughout graduate school, I didn't have the best habits. They're healthier now than they were back then. But I would drink a Diet Coke or two per day. I still have the occasional Diet Coke, I'm not completely averse to drink something that has artificial sweetener. Although, I do avoid sucralose for reasons that maybe I can get into a little bit later. But a lot of the things I consume contain stevia, which is not artificial but it is a plant-based non-caloric-- or low caloric sweetener.”

“for reasons that are entirely personal and have no scientific basis whatsoever I avoid things with sucralose in them I don't really like the taste of it and I have kind of an aversion to it”
