I had my RMR tested...

I had my RMR and body fat tested yesterday at the hospital. While I'll just leave my body fat number out of here (lol), I will say that my metabolism showed up low for someone my age/height/weight. These were my results...

I am 5'10, 24 years old. Fairly active, though I work a sedentary job.

Highest amount of calories for maintaining: just over 2100
Weight loss range: Just over 1200 and no more than 1550 (the numbers were more precise, but no one is gunning for 1234 calories in a day, exactly)

If you browse the forums, 1200 calories is "starvation mode" and we should all eat TDEE, so on so fourth. That might work for some people, but for instance, it wasn't working for me personally and now I have a clearer picture as to why.

BUT in any case, has anyone else had this test done? I find it to be pretty interesting, and fun to have a personalized number just for you :-)

First off, "starvation mode" is a widely miss-understood term and is greatly exaggerated and overused. Secondly, there is a difference between being at a high body fat % and eating a VLCD and being a little 110 Lb nothing netting 500 calories per day because they have body issues, not fat issues. Thirdly, yes...their are outliers who have medical conditions and/or otherwise don't meet the average metabolic rates per their stats...they (in this case you) would be an outlier, not the norm.

When people get on other people about the 1200 calorie thing it is because they're grossing 1200 calories and then exercising their *kitten* off and netting very low calories which doesn't give their bodies sufficient nutrients or energy to perform basic functions..their hair falls out...nails turn yellow, crack, and fall out...they wonder why....people say to eat more...then they just say **** you because obviously they know what they're doing. Usually these individuals have very little to NO weight to really lose...they just have body composition issues and EDs.

If I were you, personally, I'd consult a doctor now as well to see if there's anything else going on...hyperthyroidism, PCOS, insulin resistance, etc....

I'm a bit confused... I don't think 2100 is unusually low to maintain. My calculated TDEE is something like 2200. I'm 24, female, 5'6", 157 lbs, fairly active.

I also am a bit confused about the weight loss range they gave you. If they stated you must eat no more than 1500 per day to lose weight, that sort of implies that you'd be maintaining at 1600, as opposed to eating anything less than 2100. Are they shooting for a 1-2 lb/week weight loss goal?

or she could still be losing at 1600+ a week. But losing .05lbs a week might not be a viable weight loss plan by eating just a hair under your tdee...

I am having mine done today, and also will find it interesting to have my own numbers. I had the body fat testing done last week.
These are offered at the wellness center that is run by my employer (a hospital) and the tests are given to anyone who wants them for a nominal fee. The fee includes consultation with a trainer to recommend a personal diet and work out plan based on your goals and results. I think it was well worth the money.

You breathe through a tube into a fancy machine, after fasting and consuming no stimulants, for 10 minutes in a dark quite room... it measures the gasses you breathe out. I, personally, played Candy Crush while this went on haha.

Candy crush is a stimulant. It seems to me it probably changed the outcome of the test.

This makes no sense. If your maintenance is 2100, any calorie consumption under that amount would be in the "weight loss range." 1200 would be a really aggressive deficit.
