This question is about Cycling
In theory, approximately 30-60 minutes of cycling per day (250-500kcal energy expenditure) is needed to lose 0.5-1 pound per week if dietary intake remains the same. However, in practice, the amount of cycling required to lose weight most likely varies from person to person and depends on factors such as sex, age, genetics, exercise intensity, medications, and more.
According to Harvard University, a person can burn anywhere from 315-441 kcal in 30 minutes on a stationary bike and between 240-336 kcal cycling outdoors for 30 minutes between 12-13.9 mph [ 1
