First of all, the weight that you lose from sweating is an illusory loss because it it just water, not fat. Further, you must replenish the water lost or you will dehydrate, which is unhealthy and can be dangerous.
The reason you sweat is to naturally cool the body because as sweat evaporates it takes heat away from the body.
If you run in summer with a heavy jacket, you may overheat, which is unhealthy and in extreme can be quite dangerous and even cause irreversible brain damage.
If you want to lose weight faster when running, carry light weights in your hands and swing your arms.
