Summary

This study tests whether a plant-based diet is practical for overweight people with MGUS or smoldering multiple myeloma, conditions that can lead to multiple myeloma. For 12 weeks, 23 participants receive two pre-made plant-based meals daily. Researchers track weight loss and diet adherence to see if this approach could help prevent cancer progression.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: plant-based meals
What this could lead to: If this diet is feasible and effective, it could point toward a simple dietary approach to help prevent multiple myeloma in high-risk individuals.
What could go wrong: This is a very small pilot study with only 23 participants, so results may not apply to everyone. It tests feasibility, not whether the diet actually prevents cancer.
