@NurseDee - I've said it before on the forum, and I'm 100% certain I'll say it again at some stage, but the thing about sustained Change is the individual required to make those changes has to want to do it. Everyone has their "right time", as we so often see with former smokers who tried gazillions of times before they eventually gave up.
Aside from anything else, her motivation has to come from within her.mmshe has to identify what she wants, and in my experience, both personally and professionally, "better" isn't a good enough reason. Preventing some action works less well too. Doing something positive with a real answer to the question, "what's in it for me?" Is the key.
For me, at diagnosis, I was about to embark on a long overseas trip, and the last thing I wanted was to be, from that point forward, tethered to a pharmacy every month for a repeat prescription. I wanted the drug free life I loved, and I wanted to be well. To live the life I do, I need to be well.
So I decided to take the big D and shake it by the throat until it fought no more.
So, what was in it for me? Remaining drug free. Continuing to have my freedom from what I felt would be intrusions into my life filling prescriptions), and having the almost boundless energy to be as active as I want to be, and that's certainly more active than many 59 year olds. My OH, although 10 years older than me is equally vital and I wanted to be able to continue to party in our own ways for some time longer.
For me, I want to still have all my toes in 10 years was too far away. It had to be something in the now, and I have to be able to gauge if I was achieving it.
My feedback loop was my glucose testing meter and actually, although I didn't ever set out to reduce weight, I got skinny along the way.
So, I think what I'm saying is this is her issue to deal with in her way. If she lives with you, and you do the shopping, you can control some of what she eats, but at 23, she islikely to know how to shop for what she wants.
Only you will know what sort of conversation you could have, but to be honest, if you are doing well and losing weight, she may just get curious along the way and decide to join you on the journey, even nif she doesn't want to discuss it much.
It's a horrid situation, but as I say, she is the one with all the actions, unless she asks for some help.
Good luck to you both.
