RMR TEST RESULTS ?????

Hello,

I had my rnr tested with the BODYGEM device

RMR was 1570

I said my lifestyle was active which equals 2.3 mets

I figured 10 hours per day / 70 per week I am "working" as a stay at home Mom

so 1570 (RMR) X .542 (FACTOR) = 850.94

850.94 + 1570 = 2420.94 (TOTAL ENERGY EXPENDITURE BEFORE EXERCISE)

2100 (# of calories on average burned per week with exercise)

300 (calories on aver per day burned per day with exercise)

300 (calories burned per day) + 2420 (total energy before exercise ) = 2720 (TOTAL ENERGY METABOLISM)

So if I do not exercise I should take in 2420 to maintain my weight???

If I do exercise I should take in 2720 to maintain my weight???

But ... I was 140 - now I'm 147 - I would really like to be 138 so ... so If I want to lose 2 pounds per week minus 1000 calories = 1820 to lose ????

Is this correct??? I have been eating under this # in calories according to this- and the scale seems stuck - Do I really need to UP MY CALORIES to lose?

any help would be appreciated

thanks,
Britty

"UP MY CALORIES to lose?"

No way - your suspicions are correct - that is just not right -

2720 a day for a moderately active woman - not even close , there is NO way, I say experiment - try 2000 for a while - that is a lot of food ! I am a highly active guy at 180 & 6' and I don't even eat 2000!

There is no friggin' way you should eat 2720 a day ! You would gain weight.
You will NEVER lose weight by eating more food - that is a myth.

No problem - I think all that stuff grosly over esimates the RMR / BMR etc...

Good thing for instict.

I kind of wonder why these things are off by like 500 caloires or more too ? ! ?

My experience with RMR

I was given an RMR of 1410 and an occupational activity factor of 1.3 based on my work. This means I needed 1410 x 1.3 = 1840 calories a day to break even, not including exercise.

HOWEVER...I believe that the RMR is correct, but the activity factor isn't a very scientific guess, and I was low-balling (the counsellor said 1.4 but I wanted to err on the low side). I got a BodyBugg, which calculates every single calorie you burn, and found that I only really use about 1600/day without exercise even though my RMR has actually gone up a bit since the initial measurement, to ~1480 (yay! lost 35 lbs and increased my basic metabolism!).

So, for a very long time, I was using the 1840 number plus the read-out info from cardio machines...fine for bikes and treadmills, but I was using the elliptical and arc trainer (liars!). I thought I was burning up that 1840 plus 800 calories in the gym and should have been losing 1.5 lbs a week eating 1800/day. Well, the truth is, I was only using 2100 a day (1600 for my usual stuff, 500 on the cardio machines), not 2600. That translates to losing 2 lbs a month and not the 6 I thought I'd earned. Incredibly frustrating, started thinking I had medical problems, you name it. Now that I know the truth, I've altered my fitness plan and the numbers finally match up to the scale.

So, if you are not breastfeeding (which I believe requires an additional 500 calories/day), I'd guess you're using 2200-2300/day with exercise. Dropping to 1200 will probably make you miserable, lethargic, and ravenous given your lifestyle, so I'd recommend eating your RMR of 1570 and using your extra burn (active motherhood + exercise) as your weight loss calories. This will probably add up to 1-1.5 lbs a week, and you'll be beach-ready by Memorial Day.

SIDEBAR: Did you know that even someone who goes to the gym 3 hours a week still usually qualifies as "sedentary" because the other 165 hours are spent driving, watching TV, sitting at a computer, etc? That's where things like taking the stairs instead of the elevator, stretching your legs with a 10-minute walk at lunchtime, and all of those things that many of us think are baby steps for beginners kick in and give us enough of a "bonus burn" to justify that shot of half-and-half in your afternoon coffee. I used to think those ideas were pathetic for a gym maniac like myself, but I've seen the error of my thinking.

(((thanks a bunch))))

thanks you so much for all of your information.

It makes sense!!!!

I am going to do 1570 - and see what happens :)

Thanks for the side bar information too - very interesting!

How long do you think I should commit to the 1570 - be ore adjusting *if needed* 1 week 2????

Should I expect to see a gain - from upping the calories - initally??? since i've been under this #

thanks for your input

hugs,
Britt

RMR --- > ADJUSTMENTS

I had my RMR tested today with the Body Gem device at my local YMCA.

After speaking with a few people who are familiar with these #'s I have made a few adjustments - with my lifestyle and activity level.

Here are the #"s

RMR was 1570

I said my lifestyle which equals 1.8 mets

1570 (RMR) X .190 (FACTOR) = 298.3

298.3 + 1570 = 1868.3 (TOTAL ENERGY EXPENDITURE BEFORE EXERCISE)

2100 (# of calories on average burned per week with exercise)

300 (calories on aver per day burned per day with exercise)

300 (calories burned per day) + 1868 (total energy before exercise ) = 2168 (TOTAL ENERGY METABOLISM)

So if I do not exercise I should take in 1868 to maintain my weight.

If I do exercise I should take in 2168 to maintain my weight.

I ant to lose 7 pounds - what do you suggest???

Come on, you know the math...
3500 calories = 1 pound
Eat 500 calories less than you need and you'll lose 7 lbs in 7 weeks.

All this RMR/BMR stuff is really interesting, but really, you are over-complicating matters. In order to lose a pound a week, you need a 500 calorie per day deficit. (500 cal/day x 7 days = 3500 calories = 1 lb fat). Just eat 500 calories less per day (or exercise 500 calories more--about 5 miles jogging)...or better yet, do a combination of eating less and exercising more.

Remember that your BMR adjusts as you slim down...less mass means a lower BMR, so you need to exercise more (to burn more calories & raise your metabolism) than you did when you were heavier for the same effect. This is why it is hardest to lose those last lbs.

Hi,

I was application the egg-shaped and arc trainer (liars!). I anticipation I was afire up that 1840 additional 800 calories in the gym and should accept been accident 1.5 lbs a anniversary bistro 1800/day. 70-553, 70-559, 70-652

Keep up your exercise and drop your calories to 1350 per day. Keep very close track of the calories.

It's craziness and "magical thinking" to think you will lose weight by incresing calories.

Friday, August 27, 2010, 12:24 AM

But if it's so crazy and magical, then why does every registered dietitian say the same thing?

I went and found the actual Harris-Benedict formula and used that. Of course, I extrapolated from there based on my own voodoo magic spider sense and came up with a number I could live with.

We're humans, not robots. It's never going to be an exact science.
