GSP RushFit giving me a high BMR - this look right?

[quinnz]

Hey all,

Just starting with the GSP RushFit program and one of the first steps is to calculate your BMR. I'm a 31 year old, 6'4", 200 lb. . The calculation the nutrition guide provided with program gives for calculating BMR is:

66 x (6.3 x weight in pounds) + (12.9 x height in inches) - (6.8 x your age in years) = _________. Once you have that number, times that by 1.4 (I do light / moderate exercise per week) to get your BMR. So, for me, it looks like this:

66 + 1260 + 980.4 - 210.8 = 2095.6

2095.6 x 1.4 = 2933.84 = BMR

However, that seems a bit high no? And using any of the online BMR calculators seems to suggest as much. For example:

MyFitnessPal BMR calculator = 1,964
BMI-Calculator.net = 2066.4
FitWatch.com = 2063

1000 calories is a big difference. Any ideas on this? Want to make sure I get this right before I start the program.

Thanks,
Q

Basal metabolic rate is the minimum calorie consumption deemed necessary, to sustain healthy metabolic function.

Your calculation is not right, because in the first instance you've quote the required calculation as beginning with "66x", but in your own workings you've quoted it as "66+"

Why not just try some of the online BMR calculators, for example this BMR calculator?
