Intermittent Fasting Adherence and Self Tracking

Patients randomized to the commitment device arm will be asked to visit the Way to Health platform. There, they will identify a support person, a family or friend who they speak to frequently and who is invested in their health. They will then complete a series of questions intended to create implementation intentions. Specifically, they will pick a time for their fast to begin each 24-hour period and a time for their fast to end. They will also develop strategies to deal with hunger arising during a fast period. After this process, they will sign a contract pledging to adhere to the 16:8 time-restricted feeding dietary pattern, and acknowledging that their support person will receive a copy of the contract and weekly updates about their adherence to the regimen.
