Quick-service smoothie operator Smoothie King has announced the nationwide launch of its 2026 autumn product lineup, headlined by the Slim-N-Trim GLP-1 Pumpkin Smoothie.
Positioned as the quick-service restaurant (QSR) sector's first pumpkin smoothie engineered specifically for guests taking GLP-1 weight-loss medications, the short-run limited-time offering (LTO) enters participating stores and digital channels nationwide starting 18 August 2026.
The launch builds upon the enterprise's GLP-1 Support Menu platform initially introduced in 2024, addressing expanding consumer adoption of GLP-1 receptor agonists through macro-nutrient-dense, high-satiety seasonal beverage formulations.
GLP-1 Nutrition and Seasonal Menu Engineering
The development of the Slim-N-Trim GLP-1 Pumpkin Smoothie translates peak autumn flavour trends into a functional nutritional profile tailored for GLP-1 medication patients.
Formulated with a base of 100 per cent organic pumpkin purée and a proprietary pumpkin spice blend, each serving delivers more than 23 grams of protein, 9 grams of dietary fibre, and zero grams of added sugar.
The product strategy addresses shifting dietary habits among GLP-1 patients, where reduced appetite drives demand for nutrient-dense, high-protein meal replacements and snacks that deliver essential micronutrients and fibre without high caloric density.
Lori Primavera, Vice-President of R&D and Product Marketing at Smoothie King, stated that the development strategy focused on applying the brand's nutritional formulation standards to emerging GLP-1 dietary needs, demonstrating that seasonal limited-time offerings can deliver both traditional taste profiles and targeted functional health parameters.
