As long as you exercise, you will lose weight. If you run for 50 minutes every day, you don't need to run too fast, otherwise you will feel uncomfortable. You can do it step by step. For example, run slowly today and speed up gradually, as long as you adapt yourself. As long as it is exercise, it will consume energy. Of course, jogging and running consume different energy. The faster the speed, the more consumption, but it is not absolute.

As for the effect, it depends on your specific situation and your own quality. First of all, if you are overweight all the time, it will be difficult and take a long time to lose weight. However, if you have gained weight in recent months, a little exercise will have an effect. If you are thin, running can only achieve the purpose of fitness, and the weight loss effect will not be too obvious. And after a day's exercise, don't eat too much, and you can achieve the goal of losing weight by being flat or slightly lower than before. Generally speaking, if ordinary people really insist on 50 minutes a day, it will take half a month to have an effect, and it will take at least one month to have an obvious effect.
