It may or may not
If you have a 500 kcal deficit every day, you will lose a pound a week - that should be around the 2 year mark.
If you low carb, often you find your appetite going down after the first week or two, so some of this may come naturally.
If you add to the equation a brisk walk of about 30 minutes every day, you should knock off 200 kcals on that, and it is good for your blood sugar control too.
If you have any excess skin it will have better time to adjust the slower you do the weight loss. Losing much more than 1kg a week (2lbs) is not really recommended as it is likely to mean you will be losing muscle.
I would set goals that revolve around 1lb a week loss (2 years time) and be happy about the extra that might come off before then.
Just remember how much better you will already feel in 10lbs, 20lbs time - the end goal is one thing, but the benefits from a 10 percent weight reduction are already excellent and if you say 'At Christmas, I want to have lost 25 lbs' you'd have a beautiful goal for the med-term that you are likely to achieve and then you cross the next bridge when you get to it.
You can also calculate the other way around and see how many calories you would need to get to a certain weight by a certain date as long as you don't put yourself on an absolute starvation diet. Maybe 1800 kcals would be a nice compromise.
It is far better though to have goals that you are likely to achieve than goals and expectations that get disappointed - you need the motivation and the extra bits that come off before then will then be a nice bonus.
Also remember than when you have lost say 20 lbs, you will need to look at your calorie intake again because it doesn't take the same metabolistic work to keep a smaller person on their feet, so the bit towards the end of that imaginary line may be misleading. 1900 kcals can be a lot for a small person, but will probably made a big person lose weight.
Good luck.
