So when your body is expecting food and you don’t eat you obviously get those strong hunger pains, but why does that feeling begin to die down if you leave it for a bit?

The feeling of hunger is extremely complex and differs a lot from person to person and changes over time. So we can not even start to understand how it all works together. What you are describing tends to be a common trait in humans. And it might have made people more able to withstand periods of hunger and fight through it to find more food. This would have made people more capable of bringing up their offspring to bring these genetic traits on. However we do see that the body is able to train itself to withstand instincts like this. If you rely on this to reduce your food intake without feeling hungry, for example by intermittent fasting, then the body will adapt by for example getting stronger symptoms of hunger breaking down your will to fast or preparing for the fast period by eating way more then it needs building big fat reserves.
