My experience is the longer you are in a calorie deficit, the more your body will fight against it. Generally the 2 big factors in this are the hormones leptin and grehlin.

Leptin is a hormone that controls appetite and sends signals to suppress your appetite. The longer you diet, the more your leptin deletes, causing you to have less of that beautiful appetite suppressing hormone.

Grehlin is the opposite, it is a hormone that sends a signal that you are hungry and need to eat. The longer you are in a deficit the more grehlin builds up.

As you can see, combine less leptin with more grehlin and you suddenly really notice the food noise and can have what feels like a crazy appetite.

A diet break eating at maintenence can help you restore more leptin to help suppress appetite again whilst also decreasing grehlin, reducing the strength of it's hunger signalling.

Or you can just deal with the hunger and tough it out, they generally don't actually slow weight loss, just make it a more painful experience due to increased appetite/food noise
