WASHINGTON, D.C. — After one very committed individual ate nothing but Sweetgreen for 25 straight days, the salad chain has decided the right response is to find 30 more people to do it again, this time for 30 days, and to document the whole thing.

The original challenge was undertaken by Tim Donohue, who ate Sweetgreen twice a day for 25 days and, in a detail the company has chosen to feature prominently, reported that he “pooped 23 out of the 25 days” — a metric he offered with no additional context, and which the chain has since presented, in its marketing materials, as a result worth celebrating.

He spent $996.91 on 50 bowls and 20 sides over the course of the challenge, which the company notes was, in a sense, a saving, because he “bought nothing else,” a statement that is true and also, in the way that matters most, not really what anyone was asking to hear.

"He ate the same kind of food, in the same kind of bowl, twice a day, for more than three weeks, and he came out the other side *functioning.* That is not a food challenge. That is a statement about the human colon. And now we want to know if it holds for 30 more people."

The new “30 Days of Sweetgreen” campaign is recruiting participants who are “willing to eat Sweetgreen every day for 30 days and document” the experience, a phrase that, on the company’s landing page, is followed by a very specific call for people to “share their results,” which, based on the original participant’s most-cited finding, will very likely center on the bathroom.

Food experts were divided on the whole endeavor, but in a way that was surprisingly unified. “I do not understand why this is a thing,” one said. “And also, why is the company happy about it?” A second expert offered a more measured take: “The bowl is a very consistent product. That is the whole story. That is the entire article.”

THE 25-DAY BOWL: BY THE NUMBERS

  • Days of eating only Sweetgreen: 25.
  • Days with reported bathroom activity: 23. (Two unaccounted for.)
  • Cost: $996.91, which is a lot and also, per the company, a saving.
  • Items purchased: 50 bowls, 20 sides.
  • Days of the follow-up challenge: 30. People recruited: 30. Coincidence: no.

At press time, the company had not yet confirmed how many of the 30 recruited participants had completed day one, a number that, given the nature of the commitment, the company has described, in internal materials, as “in progress.”
