Is 1500 enough to loose fat?

I’m currently on a “cut” after bulking for about 2 months. I used to eat around 1900-2000 a day with about 170g of protein. Im now cutting down to 1500 with the same amount of protein PLUS 1 hour of walking on 15% at 3.7 speed.

For context: I’m F23, 5’4, and I weigh 145-147lbs.

I’m not sure if this is enough but the walking is pretty intense, and I do about 5 times a week. This is my first cut so Idk if I’m doing it correctly.

Any advice is welcome:)
