Q. How can I use a treadmill to lose weight? Will I lose weight just by running hard?
If you get out of breath and your face turns red while running, it shows some effect. However, if your appetite surges or your knees hurt afterward, you need to change your approach. It is better to exercise 1–2 hours after a meal rather than on an empty stomach. Aim for 3–4 times per week, at least 30 minutes per session. But depending on your constitution, running may actually be harmful.
