She became a beacon for women navigating their health journeys, consistently promoting body positivity and, crucially, intuitive eating. One of her most iconic and impactful projects was the "All-In" diet experiment.
The "All-In" series captivated millions as Stephanie documented her personal journey of consciously moving away from restrictive dieting and allowing her body to find its natural weight set point.

It was a testament to her courage and her belief in prioritizing long-term well-being over fleeting aesthetic goals.
