Caloric intake seeming a bit much

Hello, I am new to this community and am eager in embarking upon my weight-loss journey to success with you all. Though, I am currently a bit perplexed over caloric intake.

I am 6'2" with a large frame (ancient viking blood yarrr) and currently weigh 321 lbs. I've had my body fat % tested at 33%. If my body fat is 33% then my real lean muscle mass is 321 - (321 x .33), or, simply 215 lbs muscle. Now heres where I get caught up. Using the Katch-McArdle Formula (and yes I'm pretty good with math); the formula would be as follows:

BMR (basal metabolic rate for men and women) = 370 + (21.6 X lean mass in kg)

So, for me that means 370 + (21.6 x 97.7) which equals roughly 2500 calories a day.
Assuming I work out well 3 - 5 times a week, my exercise multiplier is 1.55 (moderate). So, my BMR x 1.55 = 3875, which is then my Total Daily Energy Expenditure (TDEE). If you create a caloric deficit by cutting the TDEE by 30% then I should, in theory, be eating 3100 calories a day.

3100 still seems like a hell of alot for me considering I come from eating 2 meals a day for the past few months at about 2000 or less total calories a day to anywhere over 3000. I know that I need to balance out my metabolism over time, but do I really need to eat so much?

My second question is: Would I most likely maximize weight loss if I cycled 3 days at 2600-2800 calories and every 4th day ate 3500 calories?

If anyone that has experience with this system could reply I would be most, most grateful! Thanks!

(formula cited from "Burn the fat, feed the muscle by Tom Venuto)

Edit note: I also am familiar with the x15 multiplier rule, but as you can see, even with that I would be consuming a ton of calories (lean body mass of 215 x 15 = 3225) I don't dare use my actual weight of 321 x 15 cuz thats insane with the result of 4815.

Hey, welcome to the forums.

You are quite the math person ;) . Your best bet is to probably stick this in the harsh truth section.

And this is just advice from me, but dont' get too hung up with numbers and calorie counting (i hardly count calories, but when I do, I make an estimate, then add 10% to that total). All you need to do is to create a calorie deficit to lose weight.
 
(i hardly count calories, but when I do, I make an estimate, then add 10% to that total). weight.

I do the exact same thing. I make sure I eat healthy foods, and just figure round about what im putting in my body. After you read the back of labels enough and eat the same foods alot it gets pretty easy.
