for quite a while. I didn't start lifting weights until October, six months in, and by that time I'd already lost 80 pounds.

Some recommend not even counting calories when you start, just make sure to count carbs. You'll find that with fats you get satiated faster. I counted calories from the start though, because I wanted to see quick results to keep me motivated. With the amount of fats I ate, I did not feel hungry all the time. If I ever did decide to eat extra, I always made sure that it was keto food, never extra carbs.

There was about a week at the start where I felt pretty awful mentally and physically. They call it the keto flu, and it's your body reacting to not having the carbs it's used to. But soon after that I felt great, much better than I did before I started.
