another TDEE question- thoughts?

soulshine23

just looking for some feedback.

i am 5lbs to go to my goal weight, it is slow going.

i have my calories set to 1350/day, which is my BMR *&* my TDEE less 20%,
and, i calculated my TDEE based on 'sedentary', because i prefer to log in my daily exercise calories and eat them back-

usually this is between 250-500 exercise calories, and i have no problem eating any and all calories each day- i am usually hungry and i love eating & drinking

but now, my job is changing and i will no longer be able to get on the treadmill to see how many calories i am burning.
but, i will be way more active in general, 5 hours of baking/prepping/office work in a kitchen, then 6 hours of waitressing, 6 days a week, compared to my current state which is fairly sub-active except for the treadmill time.

don't have or want to deal with wearing a fitbit- so, i am wondering the best way to go forward-

*change my TDEE to light or moderate and take a deficit and set that as a standard each day, and NOT eat back my burned calories (since i have no idea how many they will be?)

or

*guesstimate my calories burned and continue on at 1350/day plus whatever it is i guess the number is?

or
some other way i don't know about?

also, as i try to lose the last 5lbs, which is incredibly stubborn fat in my stomach section- should i lower the deficit % from my TDEE if i go that route? i realize i can't spot-lose, but i feel like i am never going to lose that section of flab- whether i reach my goal or not. any suggestions? more protein? no grains? not that it matters much, but i am vegan.

any help is appreciated! tia
