I Had My BMR Tested - It's 1032 Calories

bump...

Thank you for posting! I have always believed the 1200 calorie thing is untrue. On here I am finding it hard most days to hit 1200-I'm simply not hungry. Whenever I have dieted and exercised and kept my cals between 700-900 per day I have lost weight. Right now I am 5'3 135 pds and trying to drop 25 pds.. I believe with my height and weight 1200 is too high for me to intake to lose any pounds.

Tell that to your organs.

I agree that people tend to overestimate their BMR. I used to follow what the generic calculators told me from sites like MFP or any other BMR calculator out there, depending on the formula they used my BMR was estimated to be any where between 1260 and 1400, usually about 1320 was the average. Last year for about 5 weeks I started to track all of my calories, and I was very exact with it, I mostly only ate things that I knew the calories, and I was doing cardio 5x per week. After eating about 1100 calories per day, and burning an extra 2000 calories per week, after 5 weeks I got on the scale and didn't lose one pound. I was so angry, I gave up on the whole thing.

Last August I went to have metabolic testing done at an athletic club with their dietician using the breathing device. I followed the instructions to not eat 4 hours prior and to not exercise in the last 24 hours. My BMR was 970! And seeing that I didn't lose any weight when I was eating 1100-1200 calories a day, I would have to agree with this calculation. Sometimes I hate typing in my info on these sites, because they don't let you enter in less than 1200 calories a day as a goal, if I were to eat that amount, my weight would stay the same considering I did light exercise, or if I cut back on the exercise, I would GAIN weight if I ate 1200 calories per day! Those online calculators are full of crap! And don't buy into that bull**** about eating TOO LITTLE or "starvation mode", eating more calories will NEVER cause you to lose weight, if you aren't losing weight, that means your consuming too many calories, and not burning enough. I would recommend BMR testing if you want a more accurate reading.

Now I feel worried about what I am eating

The BMR/RMR formulas predict energy needs for when people are maintaining their weight by eating the maximum amount of calories. Although there will be deviations from the mean for some, your reading in particular is going to be considerably lower if you were eating 1100-1200 calories chronically.

Interesting. I can't say I'm completely shocked by it. I've used several online calculators for BMR and TDEE and found that they seemed to overestimate mine since I'd been maintaining for over a year with regular moderate to intense exercise on only slightly more than the number of calories the calculators said was my TDEE at sedentary.

Yes, I've maintained for years on well below my "Internet estimated" TDEE.

Couldn't agree more. It is not uncommon that a body will adapt to a lower RMR when suppressing calories over an extended period of time. It is rather suggested to eat at an estimated maintenance level to get a good reading. Chronic suppression for an RMR will just lead to falsely low results.

That is why I laugh when I see all these threads talking about BMR and eating more. The BMR is just an estimation. And most equations give you a higher number.

This is consistent with my personal experience.

sigh...

A test such as this measures oxygen consumption. If your BMR really is that low, eating less (or even slightly more) is a bad idea. If it's a true measure of your metabolism.. you need to figure out how to raise your metabolism. How to do that? Eat more and exercise more. If your bmr is truly this low, you have hormonal issues that are only going to get worse if you don't start eating more. Sadly.. all these threads with people eating 1000 calories a day or less is what causes this.

Sounds to me like the doc understood the basics of taking a bmr reading but is failing hard as a nutritionist.. which is quite typical.

Increase your TDEE by adding a lot more exercise.. allowing you to eat a lot more calories and get retested in a year. All of your health markers will have improved and you'll be able to eat a lot more while having a lot more energy.

If you walk on a treadmill an hour a day, that's another 600 calories to consume. If you brush your teeth, walk around, shop and function like a normal human being, that's several more hundred calories a day, putting your daily energy requirement at over 2000 and making your deficit to lose weight just slightly under that.

I totally believe this. I got the Jawbone UP, and was completely surprised when it says my BMR is 890, which is around 200 calories lower than any online calculator. For me to lose, I have to net 1200 calories. I was way over estimating how much I should be eating, until I got the Jawbone UP.

Very interesting OP post! I had a very similar experience (with a much less fancy test) using the BodyMedia and overestimating my TDEE. I was using the calulators and was thinking the "lightly active" range but after 6 months of averages using BM, it turned out my TDEE w/o exercise was about 1650 a day or "sedentary"...I had been way over eating. I have no idea what my BMR is and don't really care as I dont plan on going into a coma anytime soon...

I am kinda surprised how many people are either confused or having mispeaks...and relating their BMR to maybe TDEE??? I dont think any one should be eating less than BMR unles there is less activity than comatose.

yes. I had my BMR tested as well and it was 811. The online calculators say it is 1500 or more.

I found the post to be very interesting. Thanks for posting it.

It's good to finally read some evidence of this from someone who's been tested. I haven't been tested but I suspect my true BMR is around 900-1000 as I maintain at around 1700 including exercise and only lose if I eat 1200-1300 gross as well as lowering my carbs.

Online calculators have my BMR at 1350 and my TDEE sedentary as 1900 or 2300 with exercise which is just not possible! At one stage after believing this infoI was eating 1900 per day as I burned off around 500 calories per day through exercise but I was gaining weight and didn't start to lose when I cut at least 600-700 calories per day from this figure.
