Brief Summary:
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.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 20 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Intervention Model Description: This is a single-arm, single-center pilot.
Masking: None (Open Label)
Primary Purpose: Prevention
Official Title: A Pilot Plant-Based Dietary Intervention in Overweight and Obese Patients With Monoclonal Gammopathy of Undetermined Significance (MGUS) and Smoldering Multiple Myeloma (SMM) - The Nutrition Prevention (NUTRIVENTION) Study
Actual Study Start Date : June 3, 2021
Estimated Primary Completion Date : June 2023
Estimated Study Completion Date : June 2023

Arm Intervention/treatment
Experimental: Plant-based meals
Patients who will be administered a whole-foods plant-based diet for 12 weeks with nutrition counselling for 24 weeks.Participants will be asked to complete a survey via MSK Engage and a notification will be sent via email notification.
Other: Plant based meals
For 12 weeks, patients will receive two premade meals per day, for lunch and dinner, prepared and shipped weekly by U.S.-based WFPBD company Plantable. The meals will have a low glycemic index and contain vegetables, whole grains, and plant-based fats that have undergone minimal processing. Instructions will be provided for food storage and reheating. Detailed recommendations for snacks and breakfasts meeting the standard of a WFPBD will also be given to supplement their daily calorie needs with access to an online portal from Plantable which contains education materials and access to a coach daily for 24 weeks.

Primary Outcome Measures :
  1. Weight loss- body mass index (BMI) reduction [ Time Frame: 12 weeks ]
    Weight loss is defined as the average decrease in BMI at 12 weeks

  2. Patient adherence to the diet [ Time Frame: 12 weeks ]
    Intervention defined as ≥70% of participants consuming a WFPBD for ≥70% of meals of the 12-week intervention period (determined via a dietary recall and nutritional survey).
