Yes, same here. It's not just "I'm hungry". It's more "I cannot think about anything other than food".
I'm not sure it has anything to do with burning fat stores though, because I don't get the same feeling after say, a 3-day water fast. At that point I'm definitely hungry, but don't have the same insatiable food craving.
In fact, when I was experimenting with extended fasting, the only reason I stopped at 3 days is because I was lifting lighter weights every day and hit a point where my strength was physically depleted. I could only do about 3 reps instead of finding 15+ easy. Hunger wasn't really a problem after the first day of getting used to it.
