If you’re trying to lose weight, you’ve probably heard about fasted cardio—exercising on an empty stomach, usually first thing in the morning. But does it really help burn more fat?
In this easy-to-understand guide, we’ll break down the science, pros, and cons of fasted cardio so you can decide if it’s right for you.
What Is Fasted Cardio?
Fasted cardio means working out before eating, typically after an overnight fast (8-12 hours without food). The idea is that your body, low on glycogen (stored carbs), burns fat for energy instead.
Popular Fasted Cardio Exercises:
Running or jogging
Cycling
HIIT workouts
Walking (brisk pace)
Does Fasted Cardio Burn More Fat?
Short answer: Yes, but with some caveats.
The Science Behind It
When you exercise without eating, your body taps into fat stores for fuel since glycogen levels are low.
Some studies show increased fat burning during fasted workouts (Journal of Nutrition, 2011).
However, total fat loss over time depends on calories burned vs. consumed—not just when you exercise.
Pros of Fasted Cardio
✔ May boost fat burning during the workout
✔ Can improve insulin sensitivity (good for metabolism)
✔ Helps some people stay consistent (morning routine)
Cons of Fasted Cardio
✖ Can feel harder (low energy for intense workouts)
✖ Risk of muscle loss if overdone (body may break down protein for energy)
✖ Not ideal for long/high-intensity sessions (performance may suffer)

How to Do Fasted Cardio Safely
