Weight-loss 'stall' is very common. You still eat what was good when you weighed 9kg more... so some things may have to be adjusted down a bit. I think the most common issue when weight-loss stalls is the fact that you may simply not be creating a caloric deficit. IE your body has no need to 'shed' extra fat. Many people blame dairy, and in some people it is an alergy thing, but for others it's simply a matter of the fact that dairy products are very KJ rich. Cream is a prime example. If you have cream in your coffee and you end up having more than half a cup of cream for the day, in addition to 3 full LCHF meals. Chances are you are in 'maintenance' mode - IE providing more than enough in your diet for your body to operate, with no need for it to dig into the reserves...
