Metabolism - yes, you CAN make it better

So all fall and winter, even with having to rush home and run in the dark and the cold (okay, so not that cold), I have been running 3 times a week or at least getting something in to get at least 8k steps 4 times a week, with at least 30 minutes of "active minutes" (whatever that means to FitBit), but usually more. I am also not that far from my goal weight now and with this and that, I just haven't been tracking my food very much, but have lost maybe a pound over the last month or two, but I look much better than I have in years - lots and lots of leg muscles and my bum has a little shape due to the muscles.
Anywho, I went back to get a metabolism test done. My BMR is now 400 calories higher than where it used to be. 400 calories. A day.
For a short, middle-aged, peri-menopausal woman with just about every epi-genetic card possible stacked against her (All 4 of my grandparents survived the Dust Bowl in their formative years; 3/4 of my ancestors are descended from ethnic groups well known for the genocide and famine they've endured over the centuries.) this is amazing.
So yeah, there is a way to get your metabolism reved up, even for middle-aged ladies. The solution for me was to get the okay from my doctor, go to the running store, strap a pair of good running shoes on my feet, buy a FitBit, get out there and start running!

What is involved in a metabolism test? Did your insurance pay for it?0

So... by "metabolism," you mean "running to burn calories so in order to eat more."0
-
Start/return to any physical activity after having not done it for a good period of time will increase one's metabolic rate. That's why lots of people who just start exercising, but still even eat the same way they are now will lose weight the first couple of weeks.
But yes BMR can be raised based on intensity of exercise (and almost regardless of type of exercise).

Thanks for the encouragement op. I know a lot of frustrated ladies can use it!0

jemhh - I pay out of pocket. It's less than $100 at our local women's hospital to have it done. It's a little gross (you breathe into a device for several minutes and when you take the thing out of your mouth spit goes EVERYWHERE) but well worth it to me.
peachyfuzzle and ninerbuff - My RMR is 400 calories more than where it was many months ago when I started running. I had it tested then and I just re-tested. My food calories from exercise are in addition to my RMR.0 -
I wouldn't trust those values. You might be burning 400 more calories per day from running but I don't think there's any way your basal metabolic rate increased that much. You'd have to have gained about 60 lbs. of muscle.0

Thanks Teraliel - I was skeptical and depressed after my first test, but now I am a convert. I plan on coughing up the cash every 6 months or so for the foreseeable future to track my results and see what happens.0

Uhm, I'll trust science and the medical research. There actually was a study some years back that tracked retired ladies who started working out. . .guess what? 6 months after they started, the group that worked out 4 times a week were burning 400 calories more a day on average than they were prior to beginning their exercise regime. Which means I'm just about average, LOL!

Not to rain on the parade, but I would be skeptical of those results as well. Unless you've gained a serious amount of muscle, that is a HUGE jump in RMR.0
-
Nooooooooooooooooooooooooooooooooooooooo0

OP do you have a link maybe to the hospital or the test they use? I'm skeptical but interested.0
-
Assuming your BMR was about 1500cal a 400 increase is about 25% that seems like a remarkably large increase without increasing your muscle mass.
A 25% increase in your TDEE seems much more plausable.0 -
I would love to see that study.snarlingcoyote wrote: »WalkingAlong wrote: »I wouldn't trust those values. You might be burning 400 more calories per day from running but I don't think there's any way your basal metabolic rate increased that much. You'd have to have gained about 60 lbs. of muscle.

The info in this article is pretty much the general consensus: You can't significantly affect your BMR much, except through large weight change.

I'm on the skeptic train. BMR by that much? Not believing it. I'd buy TDEE, though.
I think you're confusing the two.0 -

It sounds like what you are talking about is an increase in TDEE (total calories burned in a day, including activity) and not BMR. Unless I am misunderstanding, you are saying that you are now burning 400 more calories per day than you did before you started exercising. That doesn't seem revolutionary, just logical.0 -
To be honest, I'm just glad you said you did it by exercise and not start banging on about products of sorcery and witchcraft (i.e. green tea)0

Here is the MATH on BMR and TDEE.
The variables for BMR include: weight, height, age
The variables for TDEE: movement. ( mostly exercise )
You increase your BMR by adding muscle mass and your TDEE by moving ( exercise )
BMR Calculation for Women: 655 + (4.35 × weight in pounds) + (4.7 × height in inches) – (4.7 × age in years)
BMR Calculation for Men: 66 + (6.23 × weight in pounds) + (12.7 × height in inches) – (6.76 × age in years)
To really determine your body’s energy needs or TDEE, you should also account for how often you exercise. Use this table to adjust the Harris Benedict Equation to account for your physical activity level:
Factoring Exercise into the BMR Equation
Amount of Exercise Daily Calories Needed
Little to no exercise BMR x 1.2
Light exercise (1 to 3 days per week) BMR x1.375
Moderate exercise (3 to 5 days per week) BMR x 1.55
Heavy exercise (6 to 7 days per week) BMR x 1.725
Very heavy exercise (intense workouts twice per day) BMR x 1.90 -
I'm not saying that this is common, or that this is the case with OP, but people never seem to mention changes in thyroid status when mentioning changes in metabolic rate (BMR).
A change in status from hypothyroid to euthyroid or from euthyroid to hyperthyroid, would result in an increase in BMR.0 -
Some are confusing BMR with RMR - not the same thing! OP said RMR...
RMR can be impacted by resistance/weight training and there is some evidence that HIIT may raise RMR (EPOC).
Conversely, calorie restriction without exercise has been shown to LOWER RMR - also endurance sports - long distance runners have been found to have lower RMR.0 -
so you increased exercise and now you have increased your TDEE because your exercise is higher?? I don't really see what is so ground breaking here..
when I bulked over the winter I increased my maintenance level from about 2600 to 2750 through eating more and gaining weight/muscle...

again, why is this ground breaking? People who went from zero exercise to exercise increased their TDEE through more activity ...
why do you think people always say eat less + move more = weight loss ..?????????0 -
What I'm not getting is how they can tell how much exercise she's getting per day by her breath.0

RMR and BMR aren't that much different. I don't think EPOC comes anywhere near to 400 calories a day.Some are confusing BMR with RMR - not the same thing! OP said RMR...

Ill go with, By the form you fill out to take the test that asks your weight, age, height and level of exercise. the exercise of course is formula and not a direct measurment if doing a BMR or RMR test.0 -
The test she's talking about wouldn't measure TDEE. While I find a 400 cal/day uptick in RMR to be fairly unbelievable also, there's no chance she's confusing the two.
"During the Resting Metabolic Rate test you will be asked to relax in a chair while your oxygen uptake, carbon dioxide output, and electrocardiogram (EKG) are measured for 16 to 20 minutes. To measure the amount of oxygen your body is using and carbon dioxide it is producing, you will be asked to wear a face mask that covers your mouth and nose (similar to an airplane pilot’s mask). The face mask will not provide you with extra air, you will only be breathing from the air in the environment. Ten EKG stickers and leads will be attached to your chest to monitor your heart rate and rhythm. It is very important that you remain as relaxed as possible to get the most accurate results. "
The EKG bit is not required for the test. Some groups use it for additional info, some don't.0 -

Didn't say EPOC accounted for a 400 calorie increase - just saying these things can impact RMR and absolute statements are not always accurate.

Measurement error.
That delta is physically impossible.0 -

For the record the OP stated BMR0 -
