Running is an aerobic exercise. Running for more than 30 minutes at a time can achieve good fat burning effect, and running can also exercise and keep fit. If you want to lose weight, you must stick to it. The longer you persist, the more obvious the effect will be. Generally, you can find obvious changes after running for about a month.

First, can running lose weight? How long does it take to lose weight? Running can lose weight, but the effect is slow, so if you want to lose weight through running, you must stick to it for a long time. If you keep running for 1-2 weeks, you can feel subtle changes in your body. But basically it will take one and a half months to have obvious effects. During this period, your weight may rebound, but don't worry. As long as you stick to it for another month and a half, the weight loss effect will stabilize. The body has inertia, which is the memory system. When it is determined that the human body is constantly exercising, the body begins to adapt to exercise and further lose excess fat. After two weeks of exercise, human cells will gradually become thinner, especially fat cells. At this time, the consumption of fat will exceed that of carbohydrates and protein, and the weight will naturally be gradually reduced. So as long as you persist, you can get good grades.

Second, how long does it take to burn fat during running? Normally, it takes about 30-40 minutes to start burning fat. The first stage of running mainly consumes sugar and water. Only when exercise reaches a certain heart rate of burning fat can we achieve the effect of losing weight. Therefore, dieters need to run for more than 30 minutes at a time to achieve the effect of losing weight and fat. If you have enough physical strength, the longer you run continuously, the better you will lose weight. The average person suggests that it should not exceed 2 hours, and the elderly or children suggest that it should not exceed 1 hour.

Third, what should I pay attention to when running to lose weight? 1. You must warm up, especially in winter. Warm-up can not only make you feel much more relaxed when running, but also reduce the possibility of injury. Warm-up before running is usually 5- 10 minutes. You can stretch your legs, turn your ankles and twist your waist. Or brisk walking+jogging to warm up and feel a little sweaty.

2. Control the running time reasonably. Generally speaking, running frequency of more than 5 times a week is the best. Run for 40-60 minutes at a time. If you run for less than 40 minutes, you can't reach the goal of burning fat. If you run for more than 60 minutes, your calf will grow muscles easily. Therefore, it is also important to control the running time.
