Any Ideas?

you know what - you are totally right.
Someone else replied to a post & reminded me not to forget about my BMR (but they didnt refer to it as BMR). My reply was that i didnt pay attention to that as that was "cake" (so to speak) & didnt include the # of cals burned by my going about the normal daily routine (or just being alive) in my calculations. 
However for some reason, it clicked w/ your post - so thank you :)

I googled "BMR" & calculated it as approx 1747.
http://www.bmi-calculator.net/bmr-calculator/

Using the Harris Benedict method for cauculating my daily caloric intake:
If you are moderatetely active (moderate exercise/sports 3-5 days/week): Calorie-Calculation = BMR x 1.55
i can see that i "should" be consuming approx 2700 cals/day.
SINCE i:
1) only consume approx 1300-1400 cals/day (1/2 the amount i should be)
2) burn an added adv of 458 cals/day (+1747=2205 total)

then THAT means...
1) i burn an adv of approx 2205 cals/day
2) my delta is approx -805 cals (1400 intake - 2205 burned)

consuming 1/2 the amount of req/ cals is not enough to lose - its just enough to maintain b/c my system has adapted & has learned how to get along w/out the other 1400 cals.

it feels like im missing something here in the equation... but basically that means that theoretically i "should" be losing weight b/c im burning more cals than i put in.
now i have to figure out why i am not.
but at least i am more aware & that in itself makes me feel better about it. :)
thanks again

Two things:

You are counting your exercise twice.

Online BMR formulas are just an estimate and can be off by quite a bit for individuals.

Here's how you are counting your exercise twice:

(1) You picked "moderately active" based on your exercise levels. So that gives you a daily calorie range that *includes* your exercise.

(2) "Burn an added adv of 458 cals/day" But those are your exercise calories. Which you included in (1).

What I do is pick my activity level based on my activity level *not* including my exercise. So it's "Lightly active" because I have a desk job (sedentary), but I also take the stairs instead of the elevator, stand up at gatherings instead of sit, take walks around the building when I get frustrated at work, etc. I don't count any of this in my recorded exercise.

Then, I record my exercise as additional calories.

As for the online formulas.... when I was 225, they claimed I should be losing 2lb. a week when I was losing 1lb because they had my BMR too high. Now that I'm 115, they claim my BMR is 1050 when it's more like 1250 according to my scale and my body fat test.

You have to take it with a grain of salt and go by what works for you. I know I can eat 1500-1700 calories not counting exercise and maintain so I adjust the numbers I put into places like TDP and MyFitnessPal.com so that they give me that as my base calories instead of the base calories they want to give me.

ah yes - thats right. thanks for pointing that out. I didnt realize that by picking moderately active that they were already including calories burned from working out.
ugh...
i have to learn how to manipulate the data for these tracking sites so they give me a more accurate information.

I just read the following on the atkins site which just about goes along with what you said (.7 - 1g - give or take .3g lol):

How much protein do I need?

The conventional wisdom is that we need at least 1.5 grams of protein per kilogram of body weight, which translates to about .7 grams of protein per pound. But the need for protein varies with many factors such as age, stress, gender and body composition (how much fat you have versus how much muscle).

Athletes clearly need more protein than non-athletes, and people trying to lose weight also do better with higher protein intakes. The best answer is that protein needs are variable, but a good rule of thumb is between 25 and 30 percent of your daily calories.  http://www.atkins.com/Science/UnderstandingNutritionAndExerc ise/Protein.aspx

SO - i am awful at math, however I did manage to calculate the .7g of protein per pound.
That said, based on a weight on 223, I should be consuming approx 156 g of protein. Thats good - I can get w/ that.

However the article goes on to say that protein needs are variable (makes sense) & that we should shoot for 25-30% of the daily caloric intake.
By that calculation - based on a 1500/day cal intake - my protein count should be 375g/day (at just 25%!!).

The 375g figure seems REALLY FLIPPING HIGH to me - but i can get w/ the 156g.

25 to 30% of my intake? Hmmm. That would be about right with their calculations..for .7 grams per pound it would be 91 grams but I consume over 100 at least a day and closer to 120..about right. But my percentage is more like 30-35% in my diet.

I'm so confused..LOL.

ME TOO!! LOL
Ok, well at least i know its NOT ME & that my calculations are on point.
w/ the % calculations, they are talking about a whopping about of protein.
That said - do you every "worry" about protein in the urine? MY sis-in-law has that (w/ her diabetis), so she cant do stuff like this. she cant have a lot of protein - now carb - no sugar. thats gotta suck!

That's 375 calories from protein, not grams. Which works out to about 94 g.

SWEET! then my calculations werent off - i just had the wrong end state LOL

THANK YOU :)

"because after 3 months I am only down 3 lbs"
That is my worse nightmare! i SO dont wan tto be killing myself working out & dieting only to not see/get any results!!!
I am so sorry you are going through this & understand the frustration you are feeling.
What Ive resulted to is reducing all forms of carbs via the Atkins diet.
Im just on my 2nd day of the induction phase, so i havent seen any "results" per say.
I started this after 2 weeks of the 5DPT as a warm up. At first, the 5D was TORTURE & i couldnt hang, but i was to determined/ stubborn/ overly competative (against myself) to let me get the better of myself. So i kept on days 1 & 2 for 4 days (basically until i got it right). Then the rest of the days were easier. The following week, days 1 & 2 breezed by with no problem.

Since I am no where near my goal & trying to get back down myself, I really cant suggest anything. I can only let you nkow that you are not alone & encourage you to not give up. Keep trying different approaches - soemthing to get your metabolism jumping again. Cut out the higher carb fruits & veggies & even the "good carbs" for a month or so & see if that works. Try the 5DPT again. Or do that one that Kaye was talking about... what was it again.... the PLATEAU BUSTER!

I've limited myself to 1100-1200 cals/day & that was actually OK when i wasnt exercising as much. Now that Im exercising more, the daily plate says i need to bump that up to like 1900 cals/day - but i find that REALLY HARD TO DO. In fact, the only i way i can achieve that is if i eat a bunch of crap & thats not what we want to do. So i pushed that down to 1400-1500 cals/day. 

I hope that helps. Dont lose heart. Stay focused - you can do it!!

Thank you all for your input and support..  I am going to start with lowering my carbs down and uping my protein so that they are equal.. Goal of 100g carbs/ 100g protein.  Maybe that may be enough to jump start things... I am going to keep my calories around 1500... (I find below that hard to keep myself in control because I get munchies at night)  and keep up the exersize.  Will hopfully let you know next week if I am seeing a move in the scales. 
Thank You
