ChronoMet: Metabolic and Inflammatory Effects of Eating Timing and Quantity

This is an observational study to address the important knowledge gap of the metabolic and inflammatory impact of acute overeating and whether timing of acute overeating may modify these effects. The hypothesis is that acute overconsumption of calories will promote inflammation and metabolic dysfunction, with the most detrimental effects observed with evening caloric overconsumption. The expectation is that this study to provide critical insights into the biological consequences of overeating, which will direct novel approaches combating overeating and its detrimental health effects.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Experimental group; 60 young (age 18-65), healthy, normal body mass index subjects for this study.	Dietary supplement: Meals; Each subject will participate in 4 visits with a 1-week washout period in between visits. Each visit will be either a morning or evening consumption of either a standardized mixed meal of containing 600 calories (standard control) or 2400 calories (overeating meal) - meals will have the same nutrient composition.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Inflammatory markers quantification	employ a the MILLIPLEX ® Human Cytokine/Chemokine Multiplex Assay Panel to quantify 50 specific inflammatory markers in the serum samples.	8 months
quantitative metabolomics on serum samples	leverage the University of Minnesota Center for Metabolomics and Proteomics to conduct analysis of serum samples utilizing the Biocrates MxP Quant 500, which provides detailed quantification of over 500 individual metabolites.	8 months
