"Take the Stress Out of Weighing In" article is perfect for this thread.

Read it if you have any questions why I looked at my non exercise calories!

To enter your exercise calories. Go to my fitness find the change my fitness goal button. Go to the bottom of the page.

There will be the question "How many calories will you burn?" or something like this. In the box type in the number calories you burn exercising in a week.

One word of caution everytime you go into change my fitness goal this box is set to zero.

Go to your start page, look down the left side, find "my goals and progress". There is a section called calories burned, under that is "change". Go there and it will ask you how many calories you burn in a week and SP will adjust your calorie intake appropriately.

Sorry, a bit off track, but I saw where it was mentioned that you can input how many calories you burn so SP can better determine how much you should be eating. Can someone tell me where to do this? Thanks!

Oh yea - Henry - I love the way you mind works! Ha Ha I really like the way you are focusing in on what is going to work for you. I get a sense that you are in this for the long haul & want to improve your health & fitness & not just "lose weight".

Keep at it!

Well said, Nancy & that's coming from a Registered Dietitian. emoticon

Nothing about weight loss is an exact science. Nothing! Everybody is different. While there are several ways to estimate your BMR, I feel the best way to look at the BMR is to see it as a guideline & adjust from there.

Henry - you will probably be adjusting your diet frequently as you lose weight and as your running mileage changes. I have to do that to my diet at times. I feel you are on the right track since you lost weight after you increased your calories. It may help to keep a journal of your food intake so you can see what is working and what is not.

Just to clarify---I was meaning more of a number constant during the rest of the calculations to get calorie ranges, not throughout life.

While I am not a Registered Dietitian or nutritionist, from all the reading I have done is that your BMR is at best a guesstimate, outside a laboratory setting. One of the simplest way (Nancy Clark's way--she is one of the country's premier Sports RDs) is to take your current weight and put a zero at the end and this is a rough guideline as to what your basal, AKA, resting metabolic rate is currently.

I do disagree that your BMR is a constant...losing weight will cause this number to go down because your body does not need the same amount of calories it did to support your previous weight. I will also add that increasing lean body mass via strength training can also skew the numbers. I had my RMR done in a laboratory setting over 5 years ago (still in the throws of my journey) and it was and astounding low 969 calories--now keep in mind this was just the number of calories my body needed to function. This did not include formal exercise or active daily living activities.

I started working with a Sports RD and we started an intensive ST program in addition to my running and today I have brought that figure up to a whopping 1500 calories (this is what my body needs if I just want to stay in bed all day and do nothing else)...even though my fat loss since that point is well over 40 pounds, I have put on well over 10 pounds of lean body mass, which is highly metabolic.

So to make a long story short, losing weight is NOT an exact science...body comp, current level of fitness, the amount of active daily living activity all comes into play on how many calories our bodies need. I think one of the biggest mistakes we do when we begin our journey is not looking at the amount of food we were eating before hand (and we must be totally honest about every bite, lick and taste we consumed) so that we have a springboard as to how many calories we will need to cut back on.

RUN SPARK STRONG!

I don't think you can figure BMR backwards---it's figured with this (from the article I linked before):

Female BMR = 655 + (9.6 x weight in kg.) + (1.8 x height in cm.) (4.7 x age in years)

Male BMR = 66 + (13.7 x weight in kg) + (5 x height in cm.) - (6.8 x age in years)


It's then treated as a constant. The bigger swing variables would be the calories in (by eating) and calories out by exercise--because those change, it LOOKS like the BMR would change, but it doesn't.

In fact, I'd say that when your calculations work out to say it's 600 or something--you're starving your body by not eating more and are making it worse for your body to try and fuel itself and to lose weight.

I've heard a story from a friend that knows a lady here on SP that went SO low in her calories for a sustained time that she is now permanently paralyzed from the waist down and in a wheelchair....so, going too low can be very bad.

I do appreciate that you would continue to "stick around" and explain what you're doing. I'm not offended, perhaps defensive because I usually think my way's right emoticon , but ultimately I do want us to come to a correct answer so that we can be on the safe side and not risk injuries because of mistake in logic somewhere (assuming one exists for this worse-case scenario of events).

Thank every one. Coach Jen gave me a link to a great article. "Having Trouble Eating Enough? Use These Calorie-Boosting Tips"

The artcle in paragraph one address my concerns on BMR . "you need to eat enough calories to meet nutritional needs, maintain a healthy metabolic rate, and stay energized"

Key here is maintain a HEALTHY METABOLIC RATE (or BMR)

Thanks again every one

Trying to recall my college stats terminology from 100 years ago -- is the problem simply that you are treating BMR like a variable when in fact it is essentially a constant? The only variables in the equation, I think, are calories eaten and calories expended.

I hope I don't sound snobbish, I am fairly geeky and love using numbers so my typing may come across poorly. Thanks for your understanding in advance.


SP takes your "BMR" in my case they use 2200. They then add the number of calories you say you burn exercising (divided by 7) to that number they subtract (with 10% fudge factors) 500 calories (1 pound loss per week) and 1000 calories (two pound loss per week).

This their calorie range. I just go backwards. Take my calories eaten add my weight loss and subtract my exercise calories, by rights this should be my BMR.

Now if this number was off by a 100 or so either way I would not worry but being off by 1000 is worrisome.

You can't change how much your body needs to live. I truly don't get that. And I'm good with math and I do have a college degree. The number that you're generating is NOT the Basal Metabolic Rate which is what "BMR" stands for....so what ARE you figuring?

Thanks MOMMY_T I use the reserves of this calculation to generate my BMR number. SP formula gives you calories need to burn 1 to 2 pounds per week. By using it in reserves one can see how well its working.

When do this I get a BMR of around 1200,

So one possibility is that I am not a 211.5 pound 55 year old male but I am a 95 pound, 101 year old female., which I maybe and this is a very bad dream emoticon

The other is I have slowed my metabolism down due to the fact I am not eating enough and am going into starvation mode.

Or there maybe other possibilities...which is why posted this thread.

Thanks again for your help

Thanks Laura.

That is what I am trying to understand. How do I balance my calories so that I do not go into starvation mode (BMR drops real low.)

I am new at this and use to think calories in - calories out = weight loss. Now I am finding out that these terms are not constant. Things like what type of calorie in is important. (sugars vs starches). Also the five mile I ran today at 8 minute pace does not burn the same numbers of calories as the same five mile at the same pace tomorrow.

This might get as fun as a 4 dimensional tensor. emoticon

I am not really calculating my "BMR" what I calculate is how many calories a day do I have to live on after I correct my intake for the number of calories I burned exercising and the number of calories from weight loss or gain.

This is a black calculation of ones BMR. So when I say my BMR was 600 per last week it means that I only used 600 calories for every thing I did except exercising, things like sleeping, typeing, walking, eating, etc.

I probably sound geeky, but I am a chemcial engineer working on a Phd in Astro-Physics, so I tend to think in terms of formulas and equations Sorry emoticon

If you go to "My Trackers" (above, just highlight to get the menu), then "Reports", then you can look at the "Calorie Differential" graphs (either daily or over a time period you specify) and see what SP calculates your BMR at. I agree--BMR does NOT change. However, how much you need to eat does change based on both BMR and exercise minutes. Because if you create too much of a difference, you won't see progress---far more intake than out, it's a gain; but far more out than in, and it could be a stay-the-same, a gain, or even a serious to permanent health problem.

(edit--what I mean is that it doesn't change much, especially not daily--it's really not something that needs to be recalculated that often.)

For the most part, if you feed all the correct info into SP, it will give you an appropriate calorie range. If you are running a lot of miles, you will find that you will probably need to keep to the high side of the range - at least that was what happened to me.

How are you calculating your BMR? BMR is something that doesn't change from day to day and it's impossible that yours is so low. Your BMR will only change when one of the factors in the equation changes like losing weight or getting another year older.

Are you eating within the range that SP gave you? If the number of calories that you told SP you are burning each week is accurate, your calorie range that they gave you will also be accurate.I've always had success eating within that range when it comes to weight loss. I will say though that at least in my experience and I know others too, it is quite hard to lose weight when your mileage is so high. It's hard to eat enough to fuel your runs, but little enough to lose weight. The balance is tricky and it may take awhile to get it right.

BMR is Basal Metabolic Rate, in other words, the calories your body uses just to be alive if you were to lay around in bed all day.

How are you figuring your BMR? There is no way it should be 600. Mine is 1451 (5'6", 157 lbs, 42 y/o, f).

"If you've noticed that every year, it becomes harder to eat whatever you want and stay slim, you've also learnt that your BMR decreases as you age." http://www.bmi-calculator.net/bmr-calculat
or/

If you put your calories burnt for the week in the section of your start page, SP will calculate what you should be eating to lose weight or maintain. Again, you have to fill in the blanks.

I posted this under a genral forum also but thought I would post it here also because I think this amybe a runners issue!

How does one get their BMR to stabilize?

Here is the data I collected over the last 6 weeks. I took some advice three weeks ago and bumped my calories up (learned how to have SP put my exercise calories into my nutritional plan) Last week was great BMR was the same as SP calculates, this week I have an all time low 600 BMR. It gets real difficult to figure out how much to eat! Over the six weeks my average BMR is 1200.

Eaten Exer Weight Loss Weekly BMR BMR
13689 5347 17850 26192 3742
13503 4647 (700) 8156 1165
13113 7894 2450 7669 1096
15736 9215 0 6521 932
18134 8532 5950 15552 2222
16889 8834 (3850) 4205 601

I guess I could be extremely efficient with my running and the 50 miles a week I have been running (9:00 pace) could only account form 2000 calories (man I am a smooth runner (lol).) This would put me at a BMR of 2200.
