What is Fasted Cardio?

Fasted cardio is a cardiovascular activity done on an empty stomach, usually in the morning before eating. During the workout, your body is supposed to use stored fat as its primary energy source. Its supporters believe it can help with fat loss and insulin sensitivity. Jogging, cycling, and jump rope activities are among the examples. However, the overall effect on weight loss and athletic performance is still being challenged.

Elevated Growth Hormone Levels: The fasted exercise may result in greater amounts of growth hormone, which has a role in fat metabolism and muscle preservation, according to certain research.
