Full Circle Weight Wellness Support
Most supplements only address one piece of the puzzle. We've closed the loop with a unique blend that addresses every part of the weight wellness journey.1
Metabolism and mental wellness are deeply connected. Your brain is one of the most metabolically demanding organs in your body, using up to 20% of your daily energy. That's why the GBX Slim2Fit Program was designed with mental wellness in mind—offering full-circle support for both the body and the mind.
At the center of this connection is the gut–brain axis—the constant, two-way communication system between your brain and gastrointestinal system. Messages travel back and forth along the vagus nerve, much like cars moving along a highway, helping coordinate hunger cues, fullness signals, mood, and motivation.
A key player in the gut–brain axis is the gut microbiome—the trillions of microorganisms that live in your gut and function as their own internal ecosystem. When your gut is supported, your brain is better equipped to support healthy choices, consistency, and overall well-being.
The GBX Slim2Fit Challenge is a 6-week holistic experience that goes beyond dieting. It's designed to help support healthier habits, mindset, and motivation by working through the gut–brain axis, supported by products and a healthy diet and exercise.
The Science of Satiety
Beyond the GLP-1 Supplement Hype
The future of metabolic health isn't in forcing change — it's in supporting connection.
Our program and products work to support the body's natural release of Cholecystokinin (CCK) — the gut's own "I'm full" signal — helping you naturally regulate hunger and fullness.4
The natural release of cholecystokinin happens when fat and protein reach the small intestine, helping coordinate digestion and signaling fullness.4
While others chase GLP-1 supplement hype, we're pioneering what's next — a holistic approach rooted in the Gut-Brain Axis.4
