First, congratulations; 10-11 kg is a great start!
Are you tracking your macros? How much of a caloric deficit are you running? Do you know if 50g of carbs is keeping you in ketosis? (20g is traditionally used because it pretty safely keeps you in ketosis, but some people can consume considerably more carbs and still stay in ketosis.)
Are any of your other metrics changing -- pants/belt size, etc. Sometimes you can drop a size without actually losing any weight.
You could try intermittent fasting. Sometimes that helps people jump-start things.
