I remember some wise chick telling me at the beginning of this journey -
We take care of the things we love.
(It may have been Torister as she is one of my heroes). That simple statement has stuck with me for the nearly 3 years I've been on this journey. This truly is about you - sure it helps to have support at home but I was never force fed. I also have a fit, active DH - sometimes he needs to add things to his meals - sometimes he needs a snack I don't keep in the house - he is really good about doing this mostly during times when we're not together. He doesn't care what size I am but he does care about my happiness - as the lifestyle changes continue we are both amazed.
As for the how - I started with baby steps - my first "rule" was no more drive thru - if I wanted fast food that was fine - but I had to get out of the car and go in - I knew myself well enough to know I wouldn't do that. Nearly 3 years later I have not had fast food.
I would also encourage you to lose the "diet" mindset. Embrace healthy choices and a healthier you.
I can't wait to hear more - take care of yourself!
