In this brief YouTube monologue, the speaker argues that while running burns more total calories, it primarily uses carbohydrates and elevates heart rate, which can increase hunger and make maintaining a calorie deficit harder.

The speaker concludes that walking is the preferable cardio for fat loss and directs viewers to a link in the bio for personalized calorie guidance.
