Nutrition Education and Community Gardening: Participants will be presented with 16 nutrition education modules based on the Portfolio Diet, through group-based virtual sessions delivered by the investigators for one year. In addition, participants will take part in two community gardening sessions during growing season, and will grow Portfolio Diet foods such as eggplant, okra, and temperate climate fruit.
Study summary
The goal of this clinical trial is to assess the effectiveness of an intervention that delivers nutrition education based on the Portfolio Diet on type-2 diabetes (T2D) risk factors among adults who are without chronic conditions, who have overweight and a high waist circumference plus one self-reported T2D risk factor. The main questions it aims to answer include:
1. What are the barriers and facilitators for effective implementation of the nutrition education intervention?
2. What is the effectiveness of the intervention on T2D risk factors?
3. What are implementation strategies for scaling up the intervention?
Participants will participate in a 12-month lifestyle intervention comprised of nutrition education based on the Portfolio Diet that includes community gardening sessions. In addition, participants will take part in pre-implementation focus groups/interviews and post-implementation focus groups/interviews.
