Fasted cardio is a form of exercise performed after a period of fasting, typically first thing in the morning before breakfast. During this time, glycogen levels are lower, so the body may tap into stored fat for fuel, which some believe can accelerate fat loss. Fasted cardio usually includes low- to moderate-intensity exercises like jogging, cycling, or walking, aimed at burning fat more efficiently.
People who practice fasted cardio are often aiming for faster fat loss, improved insulin sensitivity, or heightened metabolic efficiency. However, while some research supports fat-burning benefits, the results aren’t conclusive, and individual responses vary widely.
The downsides of fasted cardio include potential muscle loss, as the body may break down muscle tissue for energy when glycogen is depleted. It may also reduce performance, causing fatigue or dizziness, which can limit workout intensity. Moreover, long-term adherence can be challenging for those who need energy from food to feel their best during exercise.
