Like you, hunger sucked at the beginning, but now I never even notice it.
This is based on the assumption that all calories are digested and metabolized.
Calorie is simply a unit of energy. There are calories in paper, charcoal and wood, so taking that to the extreme would mean that one would gain the same amount of weight consuming a bunch of shredded paper as consuming, let's say, a donut, yet digestion does not work that way.

Output is governed by hormones, and the only reliable hack for now seems to be significantly lowering insulin by switching to ketogenic diet (or a variation thereof, /r/zerocarb, /r/keto, Atkins, Dukan). I'd recommend this book https://en.wikipedia.org/wiki/Good_Calories,_Bad_Calories with understanding that a lot of nutrition and diet science is in very premature stage because of World War 2 and lack of funding thereafter.

If I have hunger issues later on I will drink cold water or unsweetened vanilla almond milk (It's crazy, IIRC, an entire half gallon is only 200 calories).
My personal experience is that I try to only eat 1 meal per day. Intermittent fasting is nothing new, and when I combine it with a low carb diet, it is extremely effective for me. I went from ~300 down to 225 in a matter of 4-5 months.
As long as I am busy, I hardly notice any hunger during the day now that I am used to the schedule and the 1 meal makes it much harder to over eat. 2000 calories is extremely hard to take in all at once, so it basically puts you at quite a deficit just due to the logistics of eating that quantity of food in a small window of time.
