Simple Answer – Yes
Lets take the question to extremes and consider total energy budget, magnitude of deficit and length of time in a deficit.
Short term – Hours to a few days.
It's easy to imagine that over short time periods that you could exist without feeling hungry whilst in a small net calorie deficit.
Examples of this are when you wake up in the morning, between meals, when you are preoccupied with work or engrossed in something you enjoy.
Time frames of hours to even days you may not feel hungry at all whilst being in a deficit unless the deficit is exceedingly large and you are already very lean (have calories stored in fat).
‘Long’ term – Week or more.
If you are in a notable calorie deficit say of 200kcal a day or more, then after a week you will probably start to notice the effects, you are likely to be feeling hungry more often especially if you are in a large deficit.
If you are planning to sustain a deficit for a long period of time the best way to avoid feeling hunger is to be in a small deficit, a small deficit is more comfortable in terms of adaptation to normalising the feel of hunger.
So that after a period of time you no longer feel hungry per se but are subconsciously aware you are in a deficit.
If you are in an extreme deficit of the magnitude of 700kcal+ a day then you are likely to be very hungry if you sustain it for any length.
I feel that the question is too vague to give a specific satisfactory answer, so I would just refer back to the start and say YES.
