You will find a lot of Twelve Step program useful in your journey of weight loss. Much of your success in losing weight will depend on getting your mind in the right place. The tools of the twelve step program will greatly aid you to achieve the right mind set.
My father was an alcoholic and as a boy I decide that I was not going down that path and chose abstinence. However, in my determination not to go that way - I ran smack into his other failing - obesity!
I see a lot of linkages between the two alcoholism and obesity. Many of the deep seated issues are very much the same.
I see that you have been in sobriety just about the same amount of time I've maintained my weight loss. I hope that through this weight loss journey you will be able to gather greater insight and be successful - and that binging of any sort be a thing of the past.
When I started on my weight loss journey I could only manage a ten minute (slow) walk as exercise. Towards the end of my journey I could easily jog for an hour, swim for an hour and cycle on my exercise bike for an hour - and still be up for more!
This could be you! It may seem highly improbable now but I know it can be done - I've done it!
I was the wrong side of 50 years when I started this weight loss journey. I was a chronic asthmatic, bad back, ingrown toenails, had a belly hernia the size of my fist and knew nothing about weight loss. On the 1/1/2011 my weight was 153.7kg and exactly 60 weeks later (24/2/2012) I weighed in at 66.6kg - losing 87.1kg (56% off - over half of me).
Believe in yourself. It can be done...my example shows that.
More importantly - the skills that you have developed in keeping you successfully sober are the same you will need to be successful in weight loss must fill you with confidence for your future.
To that better future that awaits you!
