Study Summary
The purpose of this study is to evaluate the acute impact of ingesting individual and combined dosages of caffeine and paraxanthine in comparison to placebo on changes in resting metabolic rate, perceived levels of affect, and markers of lipolysis.
Primary Outcome
During all study visits and on six occasions during each of the seven experimental conditions (0, 30, 60, 90, 120, and 180 minutes after supplement ingestion), resting metabolic rates will be determined in a thermoneutral laboratory environment. To complete each assessment, participants will rest supine with a blanket placed over them in an environment free of auditory and visual stimuli. A clear, hard plastic shield with a transparent plastic drape will be placed over the participant's head and
Interventions

- OTHER Resting Metabolic Rate Determination
