Does this calculation sound right? BMR question

Ok, so I've been calorie counting for the last 75 days (some days I overestimated because I was away from home on short vacations or had 'days off' where I didn't count).

Because I'm a sad nerdy type I wanted to see if I could get a handle on my BMR using my stats.

I added all the daily totals for calories consumed together (whoa mama, that was a huge number!)

I multiplied my loss (36 pounds) by 3500 to give me the amount I've lost and added that on to the total above.

I took that total number and divided it by 75 (number of days). 

The number came out as 4082!  Does that mean my BMR is 4082 or did I get my number crunching wrong?

I know I'm 294 pounds, but that seems like an incredible amount for someone who's not very active!

 

No, I am afraid that is not how you work out your BMR. Seems like you're a little confused what with all the info out there! Here is how:

Take your age, height and weight and use this: http://www.bmi-calculator.net/bmr-calculator/

It'll tell you your BMR. For example, I am 5ft 11", 28 and weigh 139lbs - so mine is 1462. That is what I would burn doing absolutely nothing!

To get what you would burn in a regular day - because most people do not lay in bed all day - decide what level of activity you have and then multiply you BMR figure by the level as per: http://www.bmi-calculator.net/bmr-calculator/ harris-benedict-equation/

I hope you find this helpful.

If you like crunching numbers, I can give you the formula. I also have it in an Excel spreadsheet.

Jeff,

I love all that, please post it!

Helen.

Thanks for the replies!  I knew I had it wrong somewhere.  If only my bmr was 4000 calories a day lol

I'm sure that must work for some.  But when I use that calculator, it gives me 1375, meaning I burn that much doing nothing.  But I maintain my weight on 1200.  If I eat more, I gain.  So take these numbers with a grain of salt and learn how your own body works.

When I multiply 36 x 3500 and divide by 75 I get 1680 calories per day.

This is your calorie deficit, not your BMR.  It's higher than the 1000 calorie per day maximum that calorie count recommends.  You've also been losing over 3 lbs a week, which is more than cc recommends.  I won't pass any judgement, but you might consider slowing down your weight loss.

And congratulations on losing 36 pounds, which I hope translates into some inches lost on your waistline.

Hi thhq

I'm currently eating 2000 - 2200 calories a day and still losing.  I think I may experiment with adding 100 cals or so a day for a few days and seeing what that does. 

The weight loss is showing but the best thing is that I have so much more energy now.  I would be worried about the quick weight loss if I didn't feel so good lol

Thanks for your input!

skulder is 294 pounds, though, so 3 pounds/week *is* a safe rate of weight loss.  It's safe to lose up to 1% of your weight per week.  The 1-2 pounds guideline assumes that most users of this site are women who weigh between 100 and 200 pounds.

(9.99*m)+(6.25*s)-(4.92*a)+s, where s=+5 for men and -161 for female

m=weight in kilograms

s=height in centimeters

a= age

multiply this by 1.2 to 1.9 depending on activity.

Make sense?

Jeff, sorry to be so lazy but any chance you have that in pounds/inches?

1 kilogram =2.2 pounds

1 centimer=2.54 in

Just convert your weight and height. If you are familar with Excel, you can

enter it as a formula.
