Study focus
This study evaluated a whole food-based low-calorie diet combined with app-based digital education for managing Type 2 diabetes, resulting in significant weight loss and metabolic improvements.
This study highlights the potential of integrating digital education with dietary interventions in managing Type 2 diabetes. The significant weight loss and metabolic improvements suggest that such combined approaches may enhance patient outcomes and adherence to lifestyle changes.
