Family Based Time-Restricted Eating

Childhood Obesity Clinical Trial

Official title: Piloting a Family-Based Intervention of Time-Restricted Eating to Treat Obesity

Status Completed

Clinical Trial Summary

This study will test whether managing the hours during which people eat, called time restricted eating, might help them to lose weight. For this study, one parent and a child will enroll as a group (called a dyad). The dyads will be assigned at random to practice time restricted eating (within 10-12 hours per day) but will be able to eat whatever they would like or to limit portion size and increase fruit, vegetable and lean protein intake and limit sugar sweetened beverages and undergo . Both groups will receive dietary counseling, Bluetooth toothbrushes and scales to help monitor their progress. The study will last for 12 weeks and will have one survey four weeks after the last in person visit. There will be 2 in person visits, 7 virtual visits, 2 phone visits and daily time logs.

Clinical Trial Description

This study will provide preliminary data to demonstrate feasibility and acceptability of time-restricted eating (TRE) in the family unit, providing critical preliminary data to support NIH-level funding for a more detailed analysis of TRE in families. Obesity affects over 40% of adults and over 25% of children in the United States. Obesity - defined in adults as a body mass index (BMI) > 30 kg/m2 and in children as BMI > 95th percentile - is associated with several physical and psychological comorbidities, such as hypertension, heart disease, type 2 diabetes mellitus, and reduced quality of life. Heritability of obesity is 40-75%. Thus, if a parent is obese, children in the family have a high likelihood of also becoming obese due to both genetic and environmental factors. As such, treatments that apply to the family unit can address the public health concern of obesity at the child and adult level. Typically, obesity treatment primarily focuses on intentional caloric restriction. In adults with obesity, behavior-based weight loss programs result in weight reduction of 1-4 kg over one year. In children with obesity, lifestyle modification therapy typically results in weight stabilization, while children without treatment gain weight. Weight stabilization results in reductions in body mass index parameters (e.g., percent BMI or BMI z-score) due to increased height in children. Family-based obesity treatment also focuses on intentional caloric restriction through reduced consumption of energy dense foods, as well as increased consumption of low energy density foods, increased physical activity, and implementation of strategic parenting practices. Parent BMI change is a significant predictor of child outcomes in family-based treatment. Unfortunately, family-based interventions are typically time and resource intensive, thus limiting their receptiveness by many families. In contrast to intentionally restricting calories, time-restricted eating (TRE) intentionally restricts the eating window while allowing ad libitum intake during the window. TRE's agnostic approach to eating allows individuals to select foods that align with their needs and preferences. Multiple studies in adults, including our own, demonstrate TRE reduces weight. The postulated mechanism is that a reduced eating window reduces the number of eating occasions to reduce daily caloric intake. ;
