Yes, but the intensity of exercise is very important. At your speed, does it look like a walk or a jog? If you walk, it will take at least 4 weeks to be effective. Jogging can reduce the exercise time a little, and it is enough to exercise 1 hour every day.

If I were you, besides walking, I would consider adding some other sports, such as badminton or skipping rope, so as not to be single and unable to persist. In addition, it can consume more calories. In addition, please cooperate with light diet and low-fat and low-starch food. As the saying goes, "practice three points, eat seven points", which shows the importance of diet to slimming.

Adhere to fixed-point and regular continuous fitness, pay attention to diet and rest. I wish you success in losing weight!
