Well, I'm about 6' or 6'1" but look shorter because of my weight...
Something I noticed after losing a load of weight (6 & 1/2 stone or 91lbs, if my Maths are correct) was the change in my posture, I used to slump quite a lot, not really something you notice, or is something you can change without losing weight. Losing the weight has done wonders for the insecurities I had, those being obesity, spots and an over biting bottom jaw, which can make me look grumpy even when I am perfectly happy. Through the depression in too, when I had it.
I'm different now though? I am happy with my body, roughly 225lbs and 6"3 tall. I found that my insecurities were based on what I thought people might think of me, rather than what they actually thought of me. I've found that most people don't care and those that do I have no interest in, I have no interest in speaking to people like that so they won't become a friend. It also helps that I'm loving what I'm doing and am happy with my life, they do tend to work together. Life happiness and body insecurities. Then again, I am lucky, I have been given the nickname "Nine Inch" at college and its hilarious, a lot of people would go red faced, but it's just funny. Being laid back helps a hell of a lot though and it's definitely not the same for everyone.
I don't like how they get swept under the carpet or laughed at. To take an example which springs to mind is that of when John Prescott MP announced that he was Bulimic, people just laughed at him. It's pathetic and diseases like that are not acknowledged for what they are. A lot of people just can't be bothered to take the time to listen to the human brain, to study it, even. It's a very complicated thing and we should all do our best to help those around us who struggle. You sure as hell find out who your friends are when the going gets tough, that applies to body insecurities too.
It's not easy and it will always play a part in many peoples lives. Change is not easy, be it losing weight or gaining weight, ridding of spots or just accepting that you are who you are. I don't think it helps with the ideologies or our "perfect" society. The need to be thin. The need to be "attractive". The need to be well built. It's all a load of tosh, you are who you are, we're not robots made to the same spec, quite frankly "attractive" people are boring anyway. No personality whatsoever.
Touching on change. How easy is it? Well some things are changeable (diet, things that can be linked to it, spots, etc), though with current treatments available this list is getting shorter all the time. If somebody wants to change, they will. Losing weight or having a nose job, if it makes
you happier than do it.
Look after numero uno.
