Why a mono-diet could be the secret to weight loss - AOL

A new wave of diet debates is being framed around “mono-style” eating—rotating a limited set of meals rather than chasing constant variety. The idea leans on broader research that links plant-heavy, diverse diets with gut health and lower mortality, including a 2026 analysis across UK, US and Chinese cohorts and work from the American Gut Project. But some experts argue that reducing food choice can cut “decision fatigue,” helping people stick to meals they know suit them. An observational study in Health Psychology also reported greater weight loss among participants eating the same healthy foods daily. Clinicians warn the approach can backfire if it becomes too rigid or misses key needs.
