In a recent study, Jenny Craig and the Pennington Biomedical Research Center evaluated the effect of time-restricted eating on weight loss in patients with obesity.

Respiratory quotient (RQ) and resting metabolic rate (RMR) are approximately the same measure for our purposes. They are estimated by measuring carbon dioxide and oxygen in the breath to determine the rate of carbon dioxide production and rate of oxygen uptake.  The ratio of these two rates (CO2 productions to O2 uptake) provides an indication …
