I am 60 YO, reasonably active - walk, swim, bike, do yoga, weight training - at least one of these everyday. I weighed less than 120 my entire adult life except for pregnancies till I had a hysterectomy at age 48. I have steadily gained weight since then, especially since moving back to the mid west two years ago. I'm up to 155 now,I would say my ideal weight is about 125, so have that 30 lbs to take off, but instead, I have been gaining (5 pounds in the last year). I think I eat well but do eat a lot of butter and nuts. Have given up alcohol since Jan 2018 at least for now, see if that helps with the weight. I have never counted calories before.
