great thread. Here is my story.
I was at 300 lbs in 2009 and it was getting worse rapidly. There was this one time i had to CatScan(?) my leg and my doctor said i may need to drive to another clinic because he wasnt sure the scanunit was able to handle the weight.
I felt miserable, all the small aches were getting rediculous and at some point the lazy life was just not worth it anymore. I remember the day and even the time when it hit me, i stand up, dress and get out for a walk around the block. It was freezing, but i didnt really care.
Started walking 2-3 miles a day, dropped soda and booze, stopped eating meat (medical reasons), sweets or anything that looks like its unhealthy. Didnt have a plan or even a goal, didnt think about loosing weight, just didnt care living like that anymore.
I didnt weight myself often back then, i was heavy built all my life and grown to dislike weighting. The first time checking my weight after 3 months with my "new self" i was pleasantly suprised to see 30 lbs gone. This was the moment i started to belive it was possible for me to loose weight. You have to understand, even the thought of loosing weight was alien to me back then, it never occured to me that i could manage something like that. But seeing is beliving ...
Since then i lost 10-15 lbs each month. It was surprisingly easy, even without following any diet plans. Just eat less and move more. My personal advise would be finding something you like to do and combine it with some kind of exercise you dont hate too much. In my case it was reading. I got audiobook versions of books i always wanted to read and listen to them while walking. You just have to remember it isnt something you do for a while and then never again, i'm still walking every day in rain or snow and enjoy it quiet a bit thanks to audiobooks.
After 8 months i was down to 175lbs and feal great. Most of the small aches are gone, i can go for 10 miles and dont feel like dying. Life is good.
Thanks for listening/reading
