thank you for your reply. I am already watching what I am eating, but have not yet started tracking calories, which I plan to start doing next week, when life returns to its normal routine.
My doctor is the one who suggested walking to increase endurance and capacity of breathing. I would just like to use it as part of my exercise programme and the
get most benefit from it, both from a health point of view and also as a calorie burner. At the moment it is the only form of exercise I do.
Again, thank you for your interest in helping me.
