is RMR (resting metabolic rate) the same as BMR (base metabolic rate)?

I use software to keep track of my food/calorie intake, and exercise... the software estimates my BMR to be a little more than 3000. In order to reach my weight loss goal, I am supposed to consume 1000 calories less than my BMR

So, how accurate would this software be? Is there a basic formula to figure ones BMR/RMR? I have a pretty physical job... landscape/interiorscape work. Lots of walking, and a good bit of lifting, basically on my feet 8 hrs a day.

The diet plan I'm following suggests that in order to meet my weightloss goal, I shouldn't eat more than 1400 calories per day...

So, does this seem about right? somewhat accurate?

my first question is are you hungry?
because if you are on your feet all day, working I would not think 1400 calories would be enough for you. I would think those BMR/RMR numbers are more a ball park number, than the real number.

There are formulas online and in software for figuring BMR/RMR. According to there's about 25 different factors that determine a person's Resting Metabolic Rate (RMR) and that most of the online calculations just take into account, weight, height, age, and sex are not always accurate because they don't take these other factors into consideration. You should really go to that site and read more about what they have to say about RMR - very intersting stuff.

The software that you use that says you have a BMR of 3000 and you should have a deficit of 1000 calories sounds right assuming it has figured your BMR correctly. It is not healthy to lose more than 2 lbs. a week and you need 3500 calories a week deficit to lose 2 lbs. or 1000 deficit per day.

The diet plan you're following - if you are really at a BMR of 3000 - at 1400 calories you would have a 1600 calorie deficit which would put you at a unhealthy deficit and you could cause your metabolism to slow down by only eating 1400 calories. You need to eat 2000 calories if you have a BMR of 3000 - but again - keep in mind that 3000 number may not be accurate. The best way to know your PERSONAL RMR is to get tested - you can find a testing location at

In the above post - I meant to say you need 3500 calorie deficit per week to lose ONE pound and so 7000 calorie deficit per week to lose two pounds which also comes out to 1000 calorie deficit per day.
