How Does HIIT Impact Fat Loss and Weight Management?

There are many ways in which HIIT workouts help reduce body fat and promote healthy weight management goals. In the previously referenced 2011 research review published in the Journal of Obesity, it was found that HIIT workouts cause a striking surge in epinephrine and norepinephrine, also known as adrenaline and noradrenaline, respectively. Adrenaline and noradrenaline are your fight-or-flight hormones. These hormones are also known to ignite the breakdown or burning of fat by your exercising muscles. In addition, the surge of fight-or-flight hormones stimulates fat cells to release some of the body’s stored fat, which then becomes fuel for exercise. A 2017 study in the Journal of Diabetes Research also found that HIIT workouts have the potential to help reduce your abdominal fat stores, a process that has positive health implications. Fat around the middle of the body is highly associated with the development of heart disease and type 2 diabetes, so gradually depleting this abdominal fat is an important step in reducing a major health risk. Plus, reducing abdominal fat is one of the most common goals for people trying to improve their health and fitness.
