OBJECTIVE: To explore the lived experiences of prediabetic participants in an in-home, family-based meal kit delivery intervention for 12 weeks. Delivered foods followed a plant-dominant pattern, including small meat portions, to encourage long-term adoption of this pattern.

METHODS: Qualitative in-depth individual interviews (n = 21) were undertaken online with 7 pilot participants, at 3-time points (preintervention, during intervention, and postintervention). Three online focus groups were also undertaken postintervention with 12 participants.

RESULTS: Postintervention, most participants reported positive changes in eating patterns and mindset changes enabling future healthier eating. The deliveries inspired enthusiasm for tastier cooking and family involvement. Although participants indicated they felt well-being improvements, they often became focused on the outcome of their physical test results (eg, weight), leading to some disappointment and feelings of failure.

CONCLUSIONS AND IMPLICATIONS: Participant engagement with the intervention was high, but other underlying emotions, outside diet behavior, can affect long-term adoption outcomes. This has implications for designing future interventions.
