When scientists first reported that in high-intensity exercise, your body consumes glycogen, an energy that stores carbohydrates in the liver and muscles, and in low-intensity exercise, your body burns fat, everyone suddenly changed their exercise habits and carried out low-intensity exercise to burn fat.
Is it useful? Obviously, this won't work, because there are still many obese people, although they do low-intensity exercise, aren't they? Why is this happening?
Well, scientists are right to say that our bodies burn more body fat during low-intensity exercise such as walking or leisurely swimming. But in high-intensity sports such as running, our bodies will burn more calories. Even if some of the calories burned come from glycogen, we will burn a lot of fat calories.
When your stored glycogen is low, the carbohydrates in the food you eat will be converted into sugar to supplement your stored glycogen, but when you don't consume energy, it won't be converted into body fat.
In addition, high-intensity aerobic exercise will speed up your metabolism even after exercise. This means that your body will continue to burn fat hours after leaving the gym. This effect hardly exists in low-intensity aerobic exercise. Cumulatively, your body burns more calories during or after high-intensity aerobic exercise than low-intensity aerobic exercise.
You can inject high-intensity exercise into aerobic exercise through some interval training. You can walk fast for 5 minutes and then jog for 5 minutes. Then walk until you can't breathe, sprint for another minute and walk for another minute. From this point on, sprint and walk alternately, every minute, do this for 15 minutes, and you're done.
Stick to it for five days a week, and it won't take long for you to lose excess fat and weight steadily and healthily.
