      Various sports affect the human body healthy Conditions will have different effects, and some exercises can indeed help lose weight.

      However, if you think that you can lose weight just by participating in exercise, you are totally wrong. As far as the amount of exercise is concerned, different exercise methods, different times, and different intensities consume different calories and fat.

      engage in moderate intensity exercise

      For example, during moderate-intensity exercise, 35% of the calories consumed within 30 minutes come from fat; after 40 minutes, more than 40% of the calories consumed come from fat. After that, as time goes by, more and more fat is consumed. About 48% of the calories consumed by jogging for an hour comes from fat.

      Most of the calories consumed come from fat

      But if you exercise on an empty stomach before dinner, such as a quick walk or jog, most of the calories consumed will come from fat.

      Master the time of exercise

      Therefore, if you want to achieve the goal of losing weight through exercise, you must not only grasp the appropriate amount of exercise, but also grasp the time of exercise. "Time" is critical! Blindly performing "exercise to lose weight" may be futile and achieve nothing.

      A 100-meter race won't burn any fat

      However, when we exercise at the speed of a 100-meter race, and in more intense events such as international competitions, almost all of the calories consumed come from carbohydrates and proteins, and we cannot consume any fat. Therefore, this has no effect at all on losing weight (consuming excess fat).

      Exercise also cannot achieve the effect of weight loss

      For another example, when we do short-term exercise of less than 20 minutes in the early morning, the calories consumed roughly come from the protein and sugar in the muscles. Therefore, exercise cannot achieve the effect of weight loss at this time.
