While this is an older thread I definitely wanted to post in it.
I was overseas for 10 years and I didn't see a lot of my friends in that time.. I only saw my brother once until I returned home to Australia.
During that 10 years my weight has gone from 55 kg (about 120 lbs) at 188 cm (6'2"

up to about 98 kg when I came back to Oz... since then I've seen my brother again and my weight had gone up to 108 kg and due to medical reasons back down to about 102 kg but my gut got much bigger.
While my brother didn't comment the last time he saw me he did comment when I first moved back home, I told him it was due to quitting smoking and he was happy with that and said it was better to be fat than smoking.. can't wait until I quit again!
I'm not likely to see my brother again for about another 8 months and I'm hoping to get up to at least 110 or more kg and knowing that most of my regain and new fat goes to my gut I'm guessing he'll notice and possibly comment.
My friends haven't said a lot about it, they just accept me as I am, but a couple of them have packed on a few kgs as well...
Live and let live pretty much..
