In this segment, Eric Roberts explains the metabolic differences between high‑intensity and low‑intensity cardio and how those differences affect appetite and fat loss. He states that high‑intensity cardio primarily burns carbohydrates, while low‑intensity cardio relies on fat as the main fuel source. Because low‑intensity cardio uses fat, the body’s craving for carbs—especially sugary and junk foods—diminishes, leading to lower overall calorie consumption and greater fat loss. He recommends performing low‑intensity cardio 2 to 4 times per week for 15–30 minutes, ideally after weight‑training sessions or on rest days.
