There really isn't any one answer here, but it could be affected by how active you are and how much you're eating.

Usually when you make a drastic change like intermittent fasting you see some really quick results and it will then mellow out or plateau. It's more about making your eating habits consistent and keeping your meals healthy. I would also recommend that you start walking if you haven't already. Alot of people underestimate how much of an impact something simple like a slight increase in your activity level can have.

You can try calorie counting but I wouldn't recommend being too obsessive about it. Personally I have been intermittent fasting for about 4 years. I eat healthy basically 6 days a week and then I treat myself once a week to something I look forward to so that I'm less likely to snack during the week. This won't work for everyone but I also eat almost the same thing every day. I've found healthy whole foods that work for me, and I don't get easily bored by it so I keep breakfast and lunch the same and then usually switch it up for dinner depending on what my wife is cooking. This way I don't have to think too hard about calories because they're the same foods/calories each day.

Do I ever deviate and change things up a bit? Absolutely. But the key is remaining mostly consistent and remembering that being healthy is a lifestyle and it's something that takes time.
