Brief Summary

Randomized trial of grocery-store based nutrition counseling visits for weight management vs. in-office visits. The investigators will test pre- and post-intervention individual-level dietary quality, knowledge, self-efficacy around dietary choice, and cost of shopping, measuring difference between intervention and control arms. At the study's end, the investigators will also conduct focus groups with a subset of 20 patients (10 from each arm) and do a structured interview with the dietitian to better understand the feasibility, strengths and shortcomings of this approach. Patients who complete the main portion of the trial will be randomly selected for recruitment into a focus group and consented separately for that focus group at the end of the study.

The investigators hypothesize that, compared to office-based visits, the KP Personal Shopper visits will result in higher member diet quality scores, better nutritional knowledge scores, higher self-efficacy and confidence around food purchasing decisions, and more favorable perception of the visit by both dietician and member. The KP Personal Shopper approach may also result in increased grocery store costs for some members. Long-term, the investigators hypothesize that improvements in member perception, knowledge and dietary quality will lead to improved health outcomes.

Study Groups

Grocery-Store-Based Visit Arm

25 participants will be randomized to this arm. They will receive a baseline 30-minute phone call with the study dietitian to determine their current health problems, dietary patterns, shopping and cooking habits and health goals. They will then have 3 in-person visits with the dietitian conducted during grocery shopping trips at a local supermarket. These in-person visits will be conducted monthly over a 3 month period. The information delivered in the visits will be similar in content to that delivered in an in-office visit, including how to pick the best types of foods or ingredients for a given health condition, how to read and understand food labels, healthy recipes, how to track food and drink intake, and basic nutritional knowledge.

Group Type: EXPERIMENTAL

KP Personal Shopper Visits

Intervention Type: BEHAVIORAL

Testing co-shopping visits conducted in the grocery store (1:1 visits with dietitian while grocery shopping) versus in-office visits which are the current standard of care.

Office-Based Visit Arm

25 participants will be randomized to this arm. They will receive a baseline 30-minute phone call with the study dietitian to determine their current health problems, dietary patterns, shopping and cooking habits and health goals. They will then have 3 in-person visits with the dietitian conducted in an office at one of our medical office buildings. These in-person visits will be conducted monthly over a 3 month period. The information delivered in the visits will include how to pick the best types of foods or ingredients for a given health condition, how to read and understand food labels, healthy recipes, how to track food and drink intake, and basic nutritional knowledge.

Group Type: ACTIVE_COMPARATOR

In-Office Dietitian Visits

Intervention Type: BEHAVIORAL

Participants will have 3, 1 hour in-office sessions with the dietitian during which targeted curriculum on nutritional knowledge, weight management, healthier eating, menu and label reading, will be delivered. These visits will take place monthly over a three month period.
