When Jogging What Fat Is Burned

When I first started jogging, I was often curious about what kind of fat my body was burning during the activity. It’s a common question among fitness enthusiasts and beginners alike. After doing some research and speaking with fitness experts, I learned that jogging primarily targets body fat as a source of energy, particularly during longer, steady-state runs.

The Science Behind Fat Burning During Jogging

During jogging, the body primarily uses stored fat as a source of energy. This process occurs due to the aerobic nature of jogging, which means it utilizes oxygen to help generate energy. When we jog, our muscles require more energy, and the body taps into its fat stores to provide this energy. It is essential to understand that while jogging does burn fat, the specific fat stores burned can vary from person to person and depend on various factors such as genetics, diet, and fitness level.

The Role of Target Heart Rate

While jogging, the body’s energy source shifts from carbohydrates to fat once we reach a certain heart rate. This is often referred to as the “fat-burning zone.” At this intensity, the body is more efficient at using fat as a fuel source. It’s important to note that the fat-burning zone varies from person to person based on individual fitness levels and age.

The Types of Fat Burned

When we jog, the body primarily targets stored body fat. This includes both subcutaneous fat, which lies just beneath the skin, and visceral fat, which is located deeper in the body, surrounding vital organs. Subcutaneous fat is what we typically think of as “body fat,” while visceral fat can be more harmful to our health. Jogging helps to reduce both types of fat, contributing to overall improved health and fitness.

Caloric Expenditure

Beyond the specific fat types, jogging also aids in overall weight management by burning calories. The body enters a state of calorie deficit when the calories burned during jogging exceed the calories consumed through food and drink. This deficit leads to the body tapping into fat stores for energy, resulting in reduced body fat over time.


After delving deeper into the science behind fat burning during jogging, I have a newfound appreciation for the impact of this activity on my overall fitness and health. Whether it’s the visceral fat around vital organs or the subcutaneous fat that affects body composition, jogging proves to be an effective solution for burning fat and staying healthy. So, the next time you lace up your running shoes, remember that each step is not only propelling you forward but also burning away unwanted fat.
