Yes, it used to happen to me before every significant weight loss.

No cravings, just pure wolf-like hunger. At the time I still did fitday I could easily take in 3000 calories and still lose. I always fed that hunger because we are not supposed to starve on this WOE.......and it worked. My choices were always protein and fat dense foods......

So I'd say - feed the hunger with the right foods.
