Default Calculating Maintenance Calories/Tdee/BMR

I weigh 260 pounds according to a certain scale and 250 according to another, I am gonna say I weigh 260 to be safe haha. my bf% is roughly 29-30% height is 6'-6'1"-ish

The only activity currently is cardio and lifting. Lift M-W-F, cardio Tues.-Thurs-Sat. other than that I am sedentary as it gets, I work in computer graphics so go figure haha. I've read that most methods of calculating your maintenance calories often are misleading if you are extremely muscular or extrmely overweight. I happen to be extremely overweight.

the quick method is, from what I gather

12-13 x bodyweight=fat loss
15-16 x bodweight=Maintenance
17-19 x bodyweight=gain

the quick method puts my calories at 3120 for fat loss, sounds a lil off to me.

the more "in depth way" the The Harris-Benedict formula is:

Men: BMR = 66 + (13.7 X wt in kg) + (5 X ht in cm) - (6.8 X age in years)

Women: BMR = 655 + (9.6 X wt in kg) + (1.8 X ht in cm) - (4.7 X age in years)


so according to that my maintenance calories are 1987 or there abouts, huge difference.

so then theres the Katch-McArdle formula

BMR (men and women) = 370 + (21.6 X lean mass in kg)

that lands me at 2314

so I have these numbers
3120
1987
2314

I read that anything below 1800 for a male is unhealthy, and anyhting under 10x your bodyweight is also not beneficial...so now I am confused

if 3120 is my maintenance, I debit htat 20% and I get 2496
if 1987 is it, I debit that 20% and I get 1500 something
if 2314 is it, that puts me around 1800

2314, 1500, and 1800 are huge differences. Assuming I followed anyone of these isocaloric wise I'd be getting at least 50g under my protien requirements, or does that not matter? man this is a long post hahaha. Any help would be grrrrrreat haha

I am leaning towards the 2314 debited 20%, maybe a 50/50 split between calorie reduciton and cardio. that would put me at that oh so low 1800 and that doesnt seem right.


EDIT: ok my head is apperantly up my ass and its interfering with brain function....the BMR is too kepp your body alive, basic functions.....so going below that not good....I didnt realize there was ad ifference between BMR and TDEE. hmmm

so I am, for my lifestyle supposed to multiply my BMR x 1.375 and that puts me back around 3000 calories...haha I cant beleive that I just cant believe that...if I want to lose 2 pounds a week, I need a 7000 calorie deficit, thats about 20 minutes of excersie a day and 2500 calories, which kinda sounds right doesnt it? Sorry to do this, I need a record of my process of thought so I can see it flaws haha. I was just hoping to get away from the excersise everyday honestly haha. damnit
