How did he calculate RMR? I think that's a big question. If that itself is accurate, you could maintain your current weight eating 1659 calories a day... which, if you ate 1500/day for 3 weeks and did NOTHING else but lay in bed... you'd drop a pound. If he did that breath test thing, you have to know that eating within a few hours of testing, having caffeine within 6 or so hours of testing, or EXERCISING within 12 hours of testing may skew the results of the test... so keep that in mind when you think about your RMR.

I looked at a sample RMR report from a RMR testing company, just to understand it better. The sample report had somebody who had an RMR of 1440. They had the "maintenance" level of calories as 1440-1728, and the "starvation zone" as 1152 and under- but it seemed to only add in 30 mins of moderate exercise a day. I'm not entirely sure what that means, but perhaps it means that when you talked to the tech, you answered activity questions so he calculated the calories with a really high activity factor for you? But perhaps 1500 is actually too little for you...

Sometimes, we eat so little that our bodies stop utilizing energy the way that is most "normal." It's happened to me a few times actually (I naturally tend to undereat now... major problem, but it's hard to keep up a fast metabolism- funny for me to say because I was overweight once, but when I was 155 lbs, I was eating 4000+ calories a day and doing no real form of exercise and maintaining that... and I'm a female, 5'4". ), and it sucks. It's that "starvation mode" people talk about... it's not like you can't lose weight at all, but you just burn less and stop attacking the fat. I'm not saying this definitely happened to you, but it's a possibility, especially if your metabolic rate is a lot higher than the "typical" person your size.

Also, sometimes it takes a while to see results.

OH- with the 1500/day now, how are you tracking? Another big factor in weight loss is being 100% honest- or well, as close to honest as you can be. If you eyeball portions, stop! I strongly suggest a food scale to weigh your foods so you can be even more accurate.

I really can't help you much more than that, as I'm not certified for any of this. If I were you, I would bring the report to your Dr and ask him to look it over.

I won't comment on what you should or shouldn't be eating, rather than to say, WOW if that were me I would be totally humungous. 1600 calories is my maintain calories, but then I don't exercise a lot, either.

My question to you is this; was the tech who hooked you up and gave you the feed-back, qualified to do so? I am wondering if he learned on the job, but hasn't learned all the in's and out's to give you the appropriate information regarding calories.

Thank you. I guess the machine was off. If I ate 2400+ calories a day (even when working out) I would put on the pounds.

Also thanks for pointing out that I am clinically healthy. I don't feel it and am quite sad about my current state of affairs. Slow and steady will hopefully win the race but I have been STUCK at this weight for 2.5 years now.

The weird thing is I am very fit (can run, cycle, swim, dance etc) for a long time (and with decent times). But I just have this extra layer that won't go away....

i agree that 2lbs per week is way too much for you per week. if you had a hundred extra pounds to lose that would be another story. but you've only got about 20lbs to the top of a healthy range for your height and you're less than 2 bmi off of a healthy range. yes, you may be able to lose more, but you simply don't burn enough calories to get the nutrients you need and create a 1000 cal a day deficit. with so little to lose you should be maxing out at 1lb per week, half a pound if you are exercising anywhere near an hour a day, everyday.
i would head to your start page. look on the left hand side for your goals. make sure your height and weight is accurate and save. set a goal for 20lbs in 20 weeks if you aren't working out much, 20lbs in 30 or 40 weeks if you are working out a lot. then go in to calories burned. make sure this number is accurate to what you are burning on a weekly basis. make sure you save. then the ranges in your tracker should be accurate for where you are right now and what you are doing.

At your current weight and height, it's not very realistic to assume you can lose 2 pounds a week. If you had 100 pounds to lose, that's feasible. But the closer you are to your goal weight, the slower you're going to lose. So you might consider revising your expectation to around 1 pound per week.

I'm not sure how the tech calculated how much you should be eating, but here's a link that shows you how we come up with your recommended calorie range:

You might want to compare our BMR calculation to the information you got (keeping in mind that we multiply by 1.2 for an "activity" factor) and see if the two numbers are close.

Hope that helps,

This is only a comment but
When I started on SP I was on 1500 to 1850 cals a day so (to me) 2400 seem a lot.

See what other answers you get to see if I am right.

on my cals I was losing 2lbs a week

Today I went to my work's Health center and they hooked me up to a breathing machine for 15 minutes to calculate my Resting Metabolic Rate.

Here are my stats (as embarrasing as they are; I need help so here goes...):
Age: 37
Height: 65 inches
Weight: 159
BMI: 26.6

%Var VE: 14%
%Var VO2: 21.1%
RMR (Kcal/day): 1659

I asked the tech what to do with this information. I also stated that I want to lose 2 lbs a week. He advised me to eat 2400 calories if I am working out 1 hr a day or 2100 a day if I am working out less.

Bottom Line/Question: Was he correct with the amount I need to eat?

For the past three weeks, I have been averaging around 1500 cal/day (few higher/few lower) BUT haven't seen the scale move (minimal change in my clothing fit as well).

Looking for sound advice!
