Do you think running is more effective than walking for fat loss because the intensity is higher? Dr. Sood suggests that this may not happen.
When it comes to fat loss, many people believe that running – being a more intense activity – gives faster results. However, the key to lasting fat loss is not just in intensity, but in how your body reacts to different forms of exercise. Walking, despite being a low-impact activity, can often play a more strategic role in long-term fat management.

Anesthesiologist and pain management doctor Kunal Sood explains the key differences between walking and running – and why walking may actually be more effective for fat loss. In an Instagram video shared on October 2, the doctor explains how the body’s metabolic response differs between the two — and how it affects weight loss.
walking vs running
According to Dr. Sood, for some people walking can actually help burn fat faster than running. This is because running is a higher intensity activity than walking, which causes the body’s metabolism to function differently.
The doctor explains, “When you run, which is a high-intensity workout, your body will primarily use carbohydrates for energy. Running will also increase your cortisol. Your body will want to refuel on carbs after running. This, combined with the increase in cortisol, will increase cravings for carbs. So although running will burn more calories, it can make some people more hungry making it harder to meet the calorie deficit.”
Benefit
Although walking may be more effective for fat loss, both activities have their own benefits. While walking is a low-intensity activity that helps maintain a calorie deficit without significantly increasing appetite, running may be more effective for some individuals without strict fat loss goals. Dr. Sood explains, “There are other benefits of running such as for some people it can improve their mental health and in that case running may still be a better option for you.”
