Study under review: Time-Restricted Feeding Is a Preventative and Therapeutic Intervention against Diverse Nutritional Challenges

Introduction

Short-term fasting due to religious beliefs has been practiced for thousands of years. More recently, intermittent fasting (IF) has been becoming more popular. There are different kinds of IF, including randomly skipping a meal/meals, alternate day fasting, and using time-restricted feeding (TRF) windows.

A TRF protocol has participants consuming all of their daily energy intake within a set window of time (four hours, six hours, etc), inducing a 12-22 hour daily fasted window. While human trials are limited, an increasing number of animal studies are showing that TRF appears to be beneficial for improving many chronic disease risk factors, even while consuming a diet that should otherwise make the animal obese and diabetic[1].

Prior to this new study, however, it was not known if the benefits of TRF extended beyond protection against high-fat diets, or if TRF could be protective against excessive sugar or fructose intake. Questions also remained about TRF’s effect on pre-existing obesity, as well as its lasting effects.

Time-restricted feeding (TRF) has been a part of religious practices for thousands of years. Recently it has captured the attention of biomedical research due to promising research for disease prevention, mostly in animal studies.
