Do you factor in activity level to your tdee?

I don’t know if I’m saying it right, but like when you calculate your tdee (specifically when you’re going into a calorie deficit) do you factor in your activity level?

In the past I’ve just always chosen sedentary, but I’m starting a deficit tomorrow to prep for summer and I’d like to do 10,000 steps 6 days a week. Currently I haven’t been making hardly any steps so this would be a bit of movement for me. I also plan to do some Pilates twice a week ish.

I’ve noticed in the past when I did 10k steps regularly I’d get more hungry not all the time but like def a little more than normal in a deficit.

I’m toying with the idea of maybe choosing lightly active? In place of sedentary.

I use tdeecalculator.net to calculate my deficit / maintenance.

What do you all do?

Edited: to fix moderate to lightly active. I typed the wrong one lol.
