I was slender (118ish) until my 20s, then I married and started to enjoy food and sweets a lot more, began to put on the pounds. When I was around 30, I quit smoking and gained an additional ten pounds which I never lost. I'm okay with that though, fair exchange for the health of my lungs and feeling so much better. Although I started to actively exercise and jog, the weight was a lot slower coming off than it was going on.
Since menopause, I find it even harder to lose weight, but I try and maintain and not go up any more sizes, etc. I used to do a lot of exercise videos at home, step at home and in classes, Jazzercise and Zumba. Liked to do it all, but there were other chores or things that needed attention too. Luckily I always had physical jobs at work, so that helped keep me strong and in fairly good shape. I did count calories for awhile, but too restrictive for me, I just like to go with what I want, no strict guidelines.
My husband can eat whatever he wants and never gains much weight, I'm not like that. But, we both love good food, french pasteries, ice cream, etc. so we haven't done without. I just try to limit my serving size when eating high calorie items. Never was much for junk or fast foods, so that's a plus.
I'm 5'4", and the highest I've ever weighed was 163, wasn't very happy at that weight. Currently I'm 154, but would rather be 148ish. Seems I go up and down ten pounds depending on the season, been that way for a long time. Now I just try to put the brakes on at around 158 and don't let it go any further. I do have some muscular strength, so I'm thinking some of my weight is attributed to heavy muscles.
I do a lot of walking, daily walks every day for a couple of miles and much longer hikes when I'm out camping in wooded areas. The walking does help a lot, to keep things at an even keel. I do have a gym membership and will start going more often in the fall and winter months. Right now I'm busy doing a lot of yard work, etc., as opposed to cardio.
