Please tell me how often you ride bicycles and treadmills. This is more important. If I take a moderate average speed, I can lose 1kg to 3kg without dieting. However, if you pay attention to proper diet, such as less oil and salt, non-frying, it may be more certain than 3kg, but it is best not to fluctuate too much, otherwise it will lead to the problem of blood pressure and blood sugar and convenient metabolism!
