The good news is that all the spices and herbs are just fine, even if they do have carbs you never eat enough of them to worry about.
Ghee is fabulous stuff, no problem there.
Meat and fish and eggs are great too.
The bad news, you may need to watch the pulses, I can't eat dal anymore, but if you wanted to buy a meter you might get away with it. Shame really, dal and rice was one of my favourite meals but then that's probably why I have diabetes.
Best avoid naan, best avoid all the breads but naan is especially bad <<sigh>>.
You probably need to read around the site for a bit as that will help you to decide how many carbs you are happy to eat in a day. You will find people adopt different levels for different reasons and the choice is personal and based on your goals.
At worst some of your favourite meals will cease to be options but curries are very definitely still on the menu.
Careful of mango, it spikes my blood levels like nobodies business, and you might (will, need to wave goodbye to gulab jamun and barfi

).
