NCT04836312

Brief Summary

This pilot study will randomize 34 patients with hypertension and obesity to either time-restricted feeding alone or a commitment device to encourage time-restricted feeding, including a commitment pledge, involvement of a supportive partner, setting of implementation intentions, and multiple daily reminder text messages. The intervention will last 12 weeks, followed by a 6-week follow-up period. The primary outcome is adherence to the IF regimen, captured via daily text message, over 18 weeks

Outcome Measures

Primary Outcomes (1)

  • Adherence to the Intermittent Fasting Regimen, Captured Via Daily Text Message, Over 18 Weeks, Expressed in Days Per Week

    Adherence to the IF regimen, captured via daily text message, over 18 weeks, expressed in days per week. This will measure adherence to the IF regimen throughout the 12 week intervention period and the 6 week follow-up period.

    Weeks 1-18

Secondary Outcomes (1)

  • Adherence to the IF Regimen, Captured Via Daily Text Message, Over 12 Weeks, Expressed in Days Per Week

    Weeks 1-12

Study Arms (2)

Attention Control

NO INTERVENTION

Patients will be instructed via text message and email to fast at least 16 hours per day every day. For the next 18 weeks, they will receive a daily text message via the Way to Health platform asking if they fasted for at least 16 hours over the past 24 hours. If they fail to respond, reminder text messages will be sent. Once per week, they will receive a text message asking them to weigh themselves and check their blood pressure, and reply with the results via text message

Soft Commitment Device

EXPERIMENTAL

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.
