A first-of-its-kind seasonal offering is landing on Smoothie King's menu this fall: the Slim-N-Trim® GLP-1 Pumpkin Smoothie, a limited-time item built specifically for guests taking GLP-1 medications or anyone prioritizing high-protein, low-sugar nutrition without giving up seasonal flavor. The smoothie is available at participating locations nationwide and through the Smoothie King app starting August 18.
The new item is made with 100% organic pumpkin puree and the chain's pumpkin spice blend, delivering more than 23 grams of protein, 9 grams of fiber, and 0 grams of added sugar. It slots into the brand's GLP-1 Support Menu, which Smoothie King launched in 2024 as the first such menu from a national QSR brand — a positioning the company is now reinforcing by extending the platform into seasonal innovation.
The Full Pumpkin Lineup
The Slim-N-Trim GLP-1 Pumpkin Smoothie anchors a six-item fall pumpkin slate designed to cover a range of nutritional needs and dayparts. The complete 2026 lineup includes the Power Meal® Pumpkin (20g+ protein, positioned as a meal replacement), the Coffee High Protein Pumpkin (31g+ protein, 83mg caffeine), the Slim-N-Trim® Pumpkin (13g+ protein, 0g added sugar), the D-Lite® Pumpkin (12g+ protein), and the Vegan Pumpkin (plant-based, 12g+ protein, good source of Vitamin C). The breadth of the lineup signals a deliberate effort to capture incremental traffic across different guest wellness profiles during the high-volume fall season.
Operator and Market Context
The GLP-1 medication consumer is becoming a significant segment for foodservice operators to address directly. Lori Primavera, Vice President of R&D and Product Marketing at Smoothie King, noted that the brand saw an opportunity as guests began navigating these medications and seeking trusted nutrition guidance — applying more than 50 years of in-house nutritional expertise to the category. "Now with the Slim-N-Trim GLP-1 Pumpkin Smoothie, we're continuing to lead the category by proving that seasonal favorites can be both delicious and thoughtfully developed to support today's wellness goals," she said.
For operators tracking functional beverage and wellness trends, the Smoothie King move illustrates how established QSR brands are embedding clinical-adjacent nutrition language directly into limited-time offer strategy — not just core menus. The approach also layers loyalty mechanics on top: through the end of September, Healthy Rewards members can add a toast or flatbread to any 20 oz. pumpkin smoothie for $3.99, and a free Pumpkin D-Lite® Smoothie sampling event is set for August 27 at participating locations.
With more than 1,200 units nationwide, Smoothie King's scale means this GLP-1-forward seasonal program reaches a meaningful slice of the market. For restaurant operators exploring health-positioned menu development, it's a concrete case study in how nutrition credentials and seasonal demand can be engineered into a single product rather than treated as competing priorities. The brand's Power Eats Menu, introduced in 2025, won Nation's Restaurant News' MenuMasters Healthful Innovation award in 2026, suggesting the market is responding to its nutrition-first positioning.
The pumpkin lineup runs for a limited time at participating Smoothie King locations and through the brand's app.
