Metabolic Impact of Time Restricted Feeding
2022年9月21日 更新者:University of Minnesota
Using Novel Digital Mobile Technology to Implement Time-restricted Feeding to Improve the Metabolic Health of Overweight and Obese Participants at Risk for Developing Diabetes
The investigators are interested in how time-restricted feeding will impact weight, sleep duration and efficacy, and activity levels in obese adults.
Significant advances in digital mobile technology allow detailed measures of an individual's habits, permitting the opportunity for personalized dietary and lifestyle recommendations.
This is especially relevant as time-restricted feeding appears to promote weight loss independent of calorie intake, potentially shifting the paradigm of dietary recommendations from a calorie-based to a time-based perspective.

详细说明
Given the obesity epidemic, there is intense medical and public interest in dietary and lifestyle management to mitigate obesity and its associated complications.
Although weight loss has traditionally focused on restricting calories, it is well described that most people are unable to maintain the caloric restriction required to long term weight loss or maintenance.
This proposal will address whether restricting the timing of food intake, rather than restricting calories, may facilitate weight loss and provide metabolic benefits.
It has been recently shown that the average American eats over the course of 15 hours per day.
Such an eating cycle dictates that most people are always in a fed metabolic state and likely misaligns circadian patterns.
Time-restricted feeding (TRF) is the process of limiting food consumption to a specific window of time (e.g. 8 hours per day) and is associated with weight loss in humans and metabolic improvements in rodent studies.
Significant advances in digital mobile technology now allow further detailed measures of an individual's habits to facilitate this analysis.
Thus, the objective of this study is to test the health related effects of 12 week TRF (8 hour fed and 16 hour fasting cycle) in overweight/obese adults.
The investigators hypothesize that TRF will 1) improve sleep duration, sleep efficacy, increase activity and increase basal metabolic rate, 2) promote weight loss and lower body fat, and 3) improve insulin sensitivity and postprandial hyperglycemia.
The investigators expect these studies to show that TRF is effective and sustainable approach to improving metabolic parameters in overweight/obese individuals.
