A Study of a Plant-Based Diet in People With Monoclonal Gammopathy of Undetermined Significance (MGUS) or Smoldering Multiple Myeloma (SMM) NUTRIVENTION

What's the purpose of this trial?

This study will test whether a plant-based diet is practical (feasible) for overweight people with monoclonal gammopathy of undetermined significance (MGUS) or smoldering multiple myeloma (SMM). The researchers will decide how practical the diet is by looking at how much weight participants lose and how well they are able to stick to the diet. The researchers will also determine whether the diet is effective in preventing multiple myeloma in participants. In addition, they will look at how safe the plant-based diet is for participants, and see if the diet affects participants' quality of life.

This trial is currently open and accepting patients.

What will happen during the trial?

Patients will be administered a whole-foods plant-based diet for 12 weeks with nutrition counselling for 24 weeks.
