Finding the right BMR SUCKS!

[bboyjihad]

Hey guys, i'm trying to workout my BMR, i've tried different formulas and different websites. Everytime I try I get a different result, the lowest being 1943 cal and the highest 3239! What the hell?
Which formula is most accurate?

If anyone can help me out i'd really appreciate it.
Here are my stats:

28 years old (male)
5'11''
215lbs
177 lbs LBM
20% body fat (44lbs)
I move about a fair bit in my job (primary school teacher), always running round school!
1h 15mins weight lifting 3 times/week
40 minute run twice/week

Thanks in advance guys!

It doesn't necessarily only apply to IF diets. Best calc you can find online. Use the Katch-Macardle formula within this calculator.

Thanks alot guys! I used the Katrch-Macardle formula and my BMR came out as 2059. Doesn't that seem a little low to you guys?
That would mean I should be consuming 1500 cal during my cut.

No, bmr is calories you would eat if you lay in bed all day. You still need to factor in activity and then subtract 500 from that.

Multiply bmr by an activity factor. Then subtract cals from that to find cutting cals

ive always used michael and kendra's calculator to find my BMR and never really had any problems. What does everyone thing about this one?

I understand what you're saying but how will I know what the activity factor is? I mean say i'm moderately active, what would I times my BMR by? And by activity you mean daily activites like your job, not cardio/time in the gym right?

You're over thinking this. If you want to cut start at 2000 calories a day. Roll with it for 2-3 weeks and start dropping cals by 100 daily per week if you're not seeing results.

Screw equations.

Ok my BMR is 1564 and TDEE is 2424. So if I hit a -500cal deficit for cutting I should be munching about 1900 cal/day right???

This! Trial and error > equation! repped!

[bboyjihad]

Yep.

Thanks!

Yep!

Spend some time tracking with MyFitnessPal (or other calorie counting site) and daily/weekly weighing with PhysicsDiet. It won't take long before you've got a pretty clear idea of what your TDEE is and it's gravy after that.

Good luck, work hard, eat smart!

Thanks bro! I really wanna use 'myfitnesspal' but the iphone app just freezes when 'loading'. Apparently a problem with some jailbroken phones. Downloaded 'mynetdiary', seems pretty good for tracking calories so will give it a go.
Thanks again!

I rarely log on MFP with my phone. Usually do it with the home comp

1564 bmr for 221 lbs strikes me as low

Equations are a good starting point but trial and error will get you to YOUR figures.
