Obesity Clinical Trial - Lifestyle Intervention Feasibility for Arrhythmia

Status Completed

Clinical Trial Summary

BACKGROUND AND RATIONALE Two out of three Americans are overweight and obesity is associated with hypertension, sleep apnea, atrial fibrillation. Metabolic syndrome with centripetal obesity is also a precursor to insulin resistance and the development of Type II diabetes mellitus. While multiple strategies for weight reduction are often recommended in physician visits, calculating calories and energy expenditure is often inconvenient and does not promote compliance. Intermittent fasting, or time-restricted eating, is a methods to limit caloric intake by fasting for 16 hours to promote ketosis and suppress insulin secretion. Weight loss and reduction in body fat has been observed with brief periods of intervention as time-restricted eating results in reduction in overall caloric intake. Prospective feasibility studies and randomized comparative trials with intermittent fasting are lacking. The investigators recommend caloric restriction in all of our patients that suffer from arrhythmias and BMI >30. However, they have not systematically measured compliance and the efficacy of lifestyle interventions. Lifestyle counseling and weight loss has been shown to decrease the progression and burden of symptomatic atrial fibrillation. Intermittent fasting can result in consistent reductions in body fat and weight without specific lifestyle counseling. The aim of the present observation cohort study is to assess the feasibility of recommending intermittent fasting in an arrhythmia clinic with regard to compliance and efficacy. The investigators hypothesize that compliance and adherence to a 16/8 intermittent fasting regimen will be >25% and result in weight loss, compared to the 6 month trend prior to the intervention. This pilot study will serve as the basis to power the first randomized trial comparing intermittent fasting with other types of dietary counseling for arrhythmia outcomes. OBJECTIVES To prospectively assess compliance to prescribed intermittent fasting, measured by adherence and change in weight at 6 months.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
