The popular burger chain has introduced new high-protein menu items, joining brands like Chipotle and Starbucks in catering to protein-obsessed consumers in the U.S.
In 2026, Shake Shack has declared “same shack, new stack.”
The fast-casual chain best known for its burgers and crinkle-cut fries is the latest dining brand catering to the wellness-minded consumer (and the growing number of GLP-1 users) with the launch of its new Good Fit Menu.
The lineup reworks Shake Shack’s menu staples into lighter, high-protein options for all, including gluten-free diners, vegetarians and consumers using weight-loss medications.
The menu spans lettuce-wrapped versions of the ShackBurger and Chicken Shack, a gluten-free double beef burger served on a gluten-free bun, and a vegetarian double veggie burger made with farro and quinoa, alongside lettuce-wrapped SmokeShacks and Double Avocado Bacon Burgers. Protein counts range from the mid-20s to more than 50 grams per serving, with several options keeping carbs in the single digits.
Although the Good Fit Menu is being promoted as a limited-time rollout, the menu modifications it highlights will continue to be available.
Shake Shack’s move taps into America’s protein fixation, joining Starbucks, which launched Protein Cold Foam drinks and Protein Lattes, Sweetgreen, which has paired its protein push with new digital macro-tracking tools and Cuba Libre Restaurant, a chain of Cuban-inspired restaurants that has introduced a dedicated GLP-1–friendly menu.
More recently, Chipotle moved to formalize its protein play with the launch of a dedicated menu, targeting Gen Z (many of whom already gravitate toward the fast-casual brand) as well as gym-going Millennials focused on hitting their strength-building and protein goals.
