Substrate Utilization At Rest And Following A Meal After Acute Caloric Restriction

Carbohydrates (CHO) and fat are the predominant substrates oxidized for energy by humans. At rest, when energy demands are low, there is typically a small preference given to fat over CHO oxidation. However, following a meal or during exercise, both times of increased energy demand, many factors influence the type of fuels utilized. A non-invasive and validated technique for estimating substrate utilization is the respiratory exchange ratio...
