Not Applicable
Completed
Conditions
Hypertension
Interventions
Other: Water-only Fasting
Registration Number
NCT04515095
Lead Sponsor
TrueNorth Health Foundation
Brief Summary

This purpose of this study is to examine the safety and feasibility of water-only fasting to treat hypertensive patients.

Detailed Description

This is a prospective, open label, single arm, intervention study to examine the safety and feasibility of water-only fasting to treat hypertensive patients. Additional aims include describing mean changes in resting blood pressure as well as markers of cardiovascular health and inflammation between baseline and end of fast, end of refeed, 6-weeks post departure, and 12-months after 6-weeks follow-up.

Primary Outcome Measures
NameTimeMethod
Determine number of treatment-associated of grade 1-4 adverse events as assessed by CTCAE v5.0up to 10-60 days after baseline

Adverse events will be identified through participant interviews and medical record review

Secondary Outcome Measures
NameTimeMethod
Examine the feasibility of using fasting and refeeding in the treatment of stage 1 and 2 hypertension based on change in systolic blood pressure (SBP)Baseline, up to 10 to 40 days after baseline, up to 5 to 20 days after end of fast, 6-weeks after departure, 12-months after 6-weeks follow-up

SBP will be measured using digital blood pressure device and reported in mmHg

Examine the feasibility of using fasting and refeeding in the treatment of stage 1 and 2 hypertension based on treatment acceptabilityUp to 7-40 days after baseline and 6-weeks after end of refeed

Treatment acceptability will be assessed using the validated Treatment Adherence/Acceptability Questionnaire

Examine the feasibility of using fasting and refeeding in the treatment of stage 1 and 2 hypertension based on food acceptability6-weeks after end of refeed

Food acceptability will be assed using the validated Food Acceptability Questionnaire

Examine the feasibility of using fasting and refeeding in the treatment of stage 1 and 2 hypertension based on dietary adhernece6-weeks after end of refeed

Dietary adherence rates will be assessed using the SOS-free Dietary Screener
