help figuring my daily caloric intake

HELP!! I am 5ft5 and 133lbs. 40yrs old. Figure my BMR to be 1355. I used sedentary(1.2) to figure my daily caloric burn. (I will add my exercise seperately). All totals to 1626cal to maintain my wgt. I want to loose but CC tells me to go down to 1300 cal. Other websites tell me to decr 500cal (1100daily cal) or by 15%-20% cal (1300-1482 daily cal). I know I shouldn't go below 1355...AND I run approx 6miles a day. That's approx 600cal deficiet. I'm Confused!!! Should I eat approx 1355-1455cal and run off 600 more??or do I eat 1355+600cal?? Or something different??

I think that 1500 - 1600 cal would be a good start; unless you create 1000 cal deficit per day, I guess that you don't have to eat back.  Based on the info., I think your daily burn meter would be 1626 + 600 = 2226.  If you think you did some extra exercise (more than regular 600 cal burn), you may try to have some snack like nuts or peanut butter.

When you have less to lose, the recommended deficit is about 500 cal, I think.

It seems that your BMI is in the middle of healthy range; are you more concerned about #s on the scale or getting toned?  Just asking because I think weight training might be a good choice at your stage.

Thanks for the info. I want to get down to approx 125. THis is where I feel most comfortable. I do wgt training a couple times a week . My goal is 3x weekly. I do some lunges, abd work, and pushups after my run 4-5x weekly also. Being more toned is never a bad thing, but I feel uncomfortable in my jeans right now.

i'm also 5'5 133 lbs.  I'm 22 so my BMR is slightly higher (1450)  I try to eat 1400-1500/day regardless if I workout or not.  If I workout I usually have 1500-1550.  My goal is also 125.  Maybe lower, not really sure becaue I have never been at 125 with the amount of muscle I have now.  The last time I was 125 I actually had a higher body fat % than I do now at 133 so we will see when I get there. 

You are right about never eating below the 1355, especially becaues you are in a healthy bmi range already (only people that are out of the healthy range can get away with eating belwo their bmr occasionally)  I think you should increase the number of weight training excercises you do.  Try for 6 excercise per main muscle group (legs, back/shoulders and chest)  This will not make you gain muscle but it will maintain the muscle you do have.  Running as much as you do is certain to tear down your muscle and will in turn lower you metabolism. 

If I were you I would try eating 1500 cals/day on your sedentary days and workout days when you burn 600.  If you burn more than that I would increase your cals accordingly. 

I read an article about how much of a deficit you should have based on how much fat you need to lose.  It has an equation that tells you what deficit you can handle without losing muscle.  For me at 18% bodyfat I can only sustain a 744 cal deficit before I start to lose muscle along with fat.  I'm sure it is a similar number for you, so i would try and keep the deficit between 500-700.

Also remeber, because we dont' have very much to lose, it will seem to come off slower than the 1lb/wk, regardless of the deficit.  Take measurements because you will definitely see progress there even if you don't on the scale.

Example: i have this black and white dress (see profile pic) and when I bought it I was 128 lbs.  A few months ago at 134 lbs I could just barely zip it past the middle of my back and it was very tight around the top.  two weeks ago at 133lbs I was able to zip it no problem and it fits the same as it did at 128 (even though I'm still 5 lbs heavier) 

here is that article i mentioned: http://www.mindandmuscle.net/articles/lyle_mc donald/maximum_fatloss?page=0%2C1

Thanks for the input! I will give that a try.
