Cycling is a kind of exercise, so strengthening physical exercise should have the effect of losing weight, but cycling can't naturally lose weight. It must be related to the amount of exercise, because exercise improves the muscle system, exercise system and bone joint system, and consumes a lot of energy. According to this principle, it can consume the energy stored in fat. So you can definitely lose weight by cycling, but you should stick to a certain amount and keep it for a long time, because stopping exercise may have some rebound effects.
