Does running while fasting burn more fat?

There is no clear answer as on the one hand, during fasting periods the glycogen stores are empty. This theoretically makes the body start burning fat for energy during exercise, including running. This might be helpful for dropping fat. On the other hand, some studies show that people who fasted overnight and exercised the next morning did not lose more weight, compared to those individuals who ate before the workout. The rule of thumb is simple: if you’re aiming to shed more fat, you don’t necessarily need to follow a fasting regimen. All you need to do is burn more calories than you consume each day, sleep better, stay hydrated, and eat a healthy balanced diet.

Will I lose muscle if I do cardio while fasting?

Yes, there is a possibility for you to lose muscle while doing cardio fasting. There are even studies showing that fasting generally can lead to protein loss and obviously muscle mass. If you’re trying to build muscle mass, fasted cardio may not be a good choice for you.
