Me, too, five kilometers every night. You said you lost more than a kilo and came back the next day. This is not to lose weight. You should digest the food and then lose weight. Generally speaking, rebound means that a person keeps exercising, but after stopping, his muscles become slack and then he gains weight. You shouldn't. If you really want to lose weight, I suggest you run more at night, for example, 8 kilometers, because you can lose weight if you consume more than your energy intake, so you can run more to increase your exercise, and then pay attention to your diet and eat more vegetables and meat, but don't eat greasy vegetables. Eat an egg in the morning to supplement it, or consider running in the morning. You can try this method. I used to lose weight quickly, but now it's only at night.
