Fasting during exercise for fitness during feasting?

Fasting, feasting and the glutamatergic synapse

Obesity has reached pandemic proportions, with the United States being one of the nations most affected. Among many lines of investigation aiming to counter obesity is the examination of how energy homeostasis and feeding behavior are regulated by the brain. Feeding behavior and weight regulation are largely controlled by the hypothalamic circuitry. Key components of this circuitry are two type...

Is carbohydrate mouth rinsing a novel approach to maintain exercise performance during Ramadan fasting?

About a decade ago, carbohydrate mouth rinsing was shown to enhance endurance exercise performance. This improvement was more pronounced in a fasted compared to a fed state, suggesting that the ergogenic effect of carbohydrate mouth rinse is dependent on endogenous carbohydrate storage. Hence, indirectly highlights the potential use of carbohydrate mouth rinse as a potential strategy to mitigat...

Energy metabolism of the Virginia opossum during fasting and exercise.

Rates of oxygen consumption and CO(2) production were measured in Virginia opossums (Didelphis virginiana) during fasting and prolonged exercise to quantify changes in total energy expenditure and oxidative fuel selection. We hypothesized that fasting would cause metabolic depression and a progressive shift towards lipid utilization to spare alternative substrates. It was also predicted that pr...

Holidays, celebrations, and commiserations: measuring drinking during feasting and fasting to improve national and individual estimates of alcohol consumption

BACKGROUND Accurate measures of alcohol consumption are critical in assessing health harms caused by alcohol. In many countries, there are large discrepancies between survey-based measures of consumption and those based on alcohol sales. In England, surveys measuring typical alcohol consumption account for only around 60% of alcohol sold. Here, using a national survey, we measure both typical d...
