Hi Mrs ( can't call you fatbum) your here making the changes so you are walking the first steps. The support and advise on here is excellent and sometimes knowing that you are not alone is a great comfort.
I do go to meetings but I need to have that each Monday to keep me focused but there is nothing to say that you can't get a similar thing in your life. Ask a close friend/ partner to help, set a WI day and they must come to your house same time each week and weigh you. If you know this is happening you are more likely to stay on track.
I wish you lots of luck and positive thoughts
