Well I have an interesting set of challenges - I am 5'2" and currently around 213 (210 was my prepregnancy weight, but I went on a week long vacation and gained while gone - I've actually lost two pounds since coming home!), down from the mid-250's when I began and a high of 270-something during one of my pregnancies.
I have a hard time figuring out a goal weight because I carry a shocking amount of lean mass for my height. For example, my shoulders, JUST BONES, are several inches broader than my husband's (he's 6'2", 225 lbs). My wrist and elbow measurements put me in the 'very large frame' category, and I have a heavily muscled natural build. When I was 160, as a high schoolers, I could have lost ten pounds - but I was roller blaring and walking daily, as well as playing soccer and figure skating multiple times a week. I was a 12/14 and looked pretty darn good.
So my BMI says my high end 'normal' weight is 132 or so... But I would literally have to starve myself and waste away muscle to get down there! Despite my height, I am not a dainty or small girl and have had to adjust my body image and expectations to match that. I am pretty and strong, but NOT delicate.
So figuring out a goal weight and size is such a challenge, beyond vague expectations, because I am SO different than every other short gal I know. I know I can get down to 160, because I've been there, but beyond that it is just a guessing game as to what looks and feels good, as well as being easily maintainable through life. It can be a little disheartening that my first major 'goal' is what other women declare to be their 'last straw, look terrible' weight.
I was HOT at 160
So yeah, being short does present challenges, and being short with a ridiculously sturdy build presents a special set. But this is what God gave me and I can work with it. On the one hand, I have a real benefit, in that I don't need to go as far down the scale to look really healthy, but it makes FINDING that happy spot a very personal challenge, with few health markers applying.
