my TDEE

ralostaz2000

I am planning to wear my Polar sport watch for 24 hrs for 3 conscutive days in a raw and calculate my avg. Calories butrned burned during a day...and I will minus 500 on daily basis and arrange my Macros accordingly. ..

Will this give an exact numbers or around so..for my total calories burned in day?

not really... 3 days is not enough data to get an accurate read.

I calculate my TDEE based on 21 days.

If you do that for at least a couple of weeks and compare your calories in vs calories out to your actual weight loss (not the first week if you just started, since this is mostly water weight), you will get a fairly accurate idea of your TDEE. I did that back when I first started and kept a spreadsheet for a year. I found that the estimate on my tracker was pretty reasonable and often had weeks where my predicted weight loss was exactly the same as my true weight loss. Now, this only held true when I was walking and cycling as primary forms of exercise. When I started hiking and kayaking and doing strength training, it got very complicated so I would only recommend doing this if you are doing basic, steady state cardio.

The bolded part I disagree with as I lift consistently and have for 3 years, my activity tracker is typically bang on for CO and I log pretty accurately...for example last two weeks net result was 3200 calories and I lost 1lb...lifting, walking, running and logging using my Jawbone for all activity tracking.

did u get Data from ur own calculations of TDEE that much closely resembles those we get from online calculators?
I just read today..that ur TDEE could be measured by multiplying 13 with ur current weight in pounds...is that correct?

Multiplying your current weight in pds might give you an estimate for a certain activity level, another multiplier might need to be used for another activity level.

Eg my pds by 13 = 2374

An online cal for 1-3 days exercise 2179
An online cal for 3-5 days exercise 2456

I know I am lightly active the majority of the time, which MFP estimates that my TDEE is around 2080 per day.


So as a go to calculation there are probably better ways.
