Debbie -- you ask for age when you figure calories, does the number of calories needed, even if you work out, decrease as you get older? I am almost 52, 5'6" and 138. I have gained about 8 pounds I'd like to get rid of because of permenipause and a slow thyroid. I am now doing interval treadmill for 30 minutes 2 days a week, steady treadmill 1 day for 30 minutes, upper body 2 days a week and lower body 1 day a week. I'm hoping that this will trigger a weight loss if I can clean up my diet some. What do you think?
