Effect of 14:10 Time-Restricted Eating on Body Weight and Metabolic Markers

Time Restricted Feeding Clinical Trial

Official title: The Effect of 14:10 Hour Time Restricted Eating on Body Weight and Metabolic Markers: An 8-Week Pilot Study in Individuals With Obesity

Status Completed

Clinical Trial Summary

The purpose of this study is to investigate the effect of engaging in time restricted eating schedule on body weight, blood glucose, and ketones (breath acetone) in individuals with obesity.

Clinical Trial Description

There are significant metabolic and weight reduction benefits associated with time restricted feeding/eating. Time restricted eating splits the day into a period of regeneration (non-eating or natural fasting) and a period of nourishing. Providing the body a period of regeneration allows the body to go into ketosis, or the elevation in circulating ketone bodies, a byproduct of fat metabolism. Breath acetone concentration is a good predictor of ketosis and loss of body fat. In healthy individuals, low concentrations of breath acetone are 1 to 2 ppm. Engaging in weight loss via nutritional ketosis (engaging in high-fat, low-carbohydrate diets, caloric restriction diets, or fasting) increases fat utilization, resulting in increased formation of ketone bodies and breath acetone concentrations ranging from 4 to 30 ppm. In individuals with obesity, nutritional ketosis facilitates weight loss and improves insulin sensitivity, lipid profile, and reduces inflammatory markers. This study will investigate the effect of participating in two different time restricted eating schedules for 8 weeks on body weight, blood glucose, and ketones. After being informed about the study and potential risks, all eligible participants giving written informed consent will be randomized to a different time restricted eating schedule (ie, one group fasts for a longer period of time). In both of these groups, fasting will begin each evening and end the following morning. This is a remote study. All procedures will be conducted at home. ;
