Comparison of morning vs evening exercise on weight loss and related health behaviors in individuals with overweight or obesity: study protocol for a 56-week randomized controlled trial (TIMEX)

Seth A. Creasy, Katrina M. Oselinsky, Erik A. Willis, Ann E. Caldwell et autres

BACKGROUND: Aerobic exercise is recommended for weight management. Recent evidence suggests that there may be time-dependent differences in how exercise affects body weight and energy balance regulation. The primary purpose of this study is to determine the effect of morning versus evening …

Examining the Role of Sleep in Body Weight Regulation and Implications for Obesity Treatment: A Narrative Review

Rebecca C. Rosenberg, Matthew J. Breit, Kevin C. Clark, Josiane L. Broussard et autres

Despite significant public health efforts to counter the obesity epidemic, approximately 50% of US adults will have obesity by 2030. The cornerstone of obesity treatment is a behavioral intervention promoting negative energy balance via a reduced-calorie diet and increased physical activity. Behavioral …

Using Time‐Weighted Averages of Total Daily Energy Expenditure to Estimate Energy Intake During a Weight Loss Intervention

Matthew J. Breit, Zhaoxing Pan, Danielle M. Ostendorf, Jared H. Dahle et autres

OBJECTIVE: The doubly labeled water (DLW) intake-balance method estimates energy intake (EI) during weight loss using the time-weighted average of total daily energy expenditure (TDEE) and changes in body energy stores. Because TDEE declines rapidly during the early phase of weight loss, …

Effects of 4:3 Intermittent Fasting on Eating Behaviors and Appetite Hormones: A Secondary Analysis of a 12-Month Behavioral Weight Loss Intervention

Matthew J. Breit, Ann E. Caldwell, Danielle M. Ostendorf, Zhaoxing Pan et autres

Background/Objectives: Daily caloric restriction (DCR) is a common dietary weight loss strategy, but leads to metabolic and behavioral adaptations, including maladaptive eating behaviors and dysregulated appetite. Intermittent fasting (IMF) may mitigate these effects by offering diet flexibility during energy restriction. This secondary …

1908-LB: Time of Day of Exercise Alters the Metabolome in Adults with Overweight or Obesity

F. C. Hu, Rick Reisdorph, Katrina Doenges, Erik A. Willis et autres

Introduction and Objective: The time of day that aerobic exercise is performed may alter the metabolic response leading to downstream effects on cardiometabolic health. This pilot study aimed to identify metabolites that are affected by time of day of exercise using metabolomics. …

Effect of physical activity on changes in weight and aerobic capacity during an 18-month behavioral weight loss intervention

Seth A. Creasy, Danielle M. Ostendorf, Rebecca C. Rosenberg, Matthew J. Breit et autres

BACKGROUND: The objective of this secondary analysis was to examine the effect of MVPA and the time of day that MVPA (i.e., morning vs. evening) is performed on long-term changes in body weight and aerobic capacity. METHODS: Adults with overweight and obesity …

The Effect of 4:3 Intermittent Fasting on Weight Loss at 12 Months

Victoria A. Catenacci, Danielle M. Ostendorf, Zhaoxing Pan, Seth A. Creasy et autres

BACKGROUND: Long-term (≥12 months) randomized trials evaluating the efficacy of intermittent fasting (IMF) as a dietary weight loss strategy are limited. Furthermore, no studies have compared IMF versus daily caloric restriction (DCR) when both interventions are provided in the context of a …

Improving quality control procedures for the measurement of total daily energy expenditure using the two‐point doubly labeled water method

Matthew J. Breit, Nassia M. Duncan, Jared H. Dahle, Victoria A. Catenacci et autres

Rationale The precision of the doubly labeled water (DLW) method is determined by the precision and accuracy of the isotopic measurements. Quality control (QC) procedures to mitigate sample variability require additional measurements if sample duplicates differ more than a factor of instrument …

Effects of follicle-stimulating hormone on energy balance and tissue metabolic health after loss of ovarian function

Andrew E. Libby, Claudia M. Solt, Matthew R. Jackman, Vanessa D. Sherk et autres

We find no effect of follicle-stimulating hormone (FSH) on energy balance using a novel model in which rats are ovariectomized, subjected to gonadotropin-releasing hormone antagonism, and systematically given back FSH by osmotic pump. However, tissue-specific effects of FSH on adipose tissue and …
