Honestly, won't sugar coat it, the food noise is there most of the time.
What has helped me:
When craving or obsessing over a certain food, I plan it into my next weeks meal plan.
I try do mind over matter, so if I really fancy a bag of crisps but I've already used my 'snack' calories, i just think to myself, if I've burned 250 cals on exercise, I might as well of just done half the exercise as I'm eating away what I've burnt off. I then promise myself the crisps tomorrow in my 'snack budget'
I meal plan a week in advance. Being prepared is the only way for me as if I don't, I struggle to stay on track.
I've taken a progress picture with every 7lbs lost, I've done this for two years and it's amazing to see where I was and where I am.
I looked into why I was stressed and depressed and tried hard to address that. Not 100% yet but absolutely on my way! I've made lots of small changes that have made my whole mind better.
I visualise in my head how I will look if I keep on calorie counting and exercising and then look at photos of me at my biggest and tell myself I don't have to end up back to where I was.
I keep all my old clothes and every now and again try them on.
I drink lots of water as I think I sometimes just need to use my mouth 
Choosing more protein rich foods and bulking meals out with veg if I can.
I don't deprive myself, if I want to go out for a meal or a drink, I do, I just don't have the old mindset of 'that's ruined it, let's just carry on'. I think I used to do that as a form of self sabotage.
Honestly, it can be difficult at times as my husband doesn't need to lose weight and has a physical job, so I actually cook him different meals to myself. I still buy in all his snacks for work too, but he keeps these out the house.
