Quest Nutrition's closest audience match is Zach Boychuk, an athlete, at 0.76 — and no other food brand appears anywhere in the top 10 neighbors.

The shape here is broad: the top 10 scores span from 0.76 down to 0.67, with no single neighbor pulling far ahead of the rest. Zach Boychuk leads at 0.76, followed by The Tonight Show at 0.71, NBC Sports EDGE Betting at 0.71, Kiefer Sutherland at 0.70, and SiriusXM at 0.70. Tallying the subcategories across all 10 neighbors: TV Shows appears three times (The Tonight Show, NBC Sports EDGE Betting is a Website, Around The Horn, Below Deck), Athletes twice (Zach Boychuk, Cris Collinsworth), and single entries for Actors, Podcasts and Radio, Fitness, and Car Makers. The dominant subcategory pattern is TV Shows and Athletes — neither of which shares Quest Nutrition's own Food subcategory. The one fitness-adjacent neighbor, Shakeology at 0.70, is the closest thing to a thematic peer, but it belongs to the Fitness subcategory, not Food. The cross-kind character of this neighbor set is the defining structural feature: Quest Nutrition's audience shape is built around sports media consumers and TV viewers, not food or nutrition brands.

This audience's broad overlap with sports programming, athletes, and general entertainment TV suggests it is defined less by a single content niche and more by a mainstream, sports-inflected media diet.
