I am an active almost 53 year old woman who has gained 15 pounds over the last year! I run 3-4 miles about 4 times a week, and I power walk or snow shoe the other days.  I am not a big over-eater, but I do like to graze!  I have been very mindful of what I am eating since the first of the year and consistent in my exercise and I have only lost 3 pounds!! Grr.....
