It should be possible, mainly because you can control your diet and insist on riding time.

After riding a bike for five months last year, I lost 25 Jin. My waist used to be 2.7 feet, but now it's 2.5 feet.

Go to work every day 10 km, get off work 10 km, and have dinner at night 15 km, a total of 35 km a day.

For five months, we should control our diet, eat well in the morning, eat well at noon and eat less at night.

Persistence is victory, and now I have lost my appetite.
