Person enters their goal and stats into MFP to lose 1lb per week. Let's say that person's maintenance is 2000 cal and MFP spits out a 250 cal deficit per day in order to lose 1lb per week.

2000 main - 250 cal deficit = 1750 cals to eat in a normal day.

Now, let's say this person starts running and burns 300 additional cals per day so now their maintenance is 2300, so

2000 normal maintenance cals + 300 exercise = 2300 Maintenance cals

2300 - 250 = 2050 cals to lose 1lb per week.

One thing to keep in mind is, MFP will overestimate exercise cals, so most start at eating back 50% of them and adjust from there.

250 per day is only .5 lb/week
it's 500/day for 1 lb a week

It was a hypothetical just to show how the math worked, but thanks anyway.

Do you use a food scale to weigh all solid foods OP?

I hate the scale, I look at it daily, I know that is not very conducive for me. But I am looking for motivation and feeling discouraged. I am guessing the best time to weigh is in the morning and not the middle of the afternoon. I weighed the morning I was at 186.6 and went back to the afternoon weighing, I know it's crazy but I always feel like I weigh less in the afternoon. Maybe I'm just crazy?

You aren't crazy, but you will probably feel better if you can cut down on the weighing. The main thing is pick a consistent time, but it will be up and down more in the afternoon depending on what you do earlier in the day, which is why many like first thing in the morning. (There will still be inexplicable fluctuations, though.)

Here's a calculator for calories burned while running that seems accurate to me: http://www.runnersworld.com/tools/calories-burned-calculator

My spot check is about 100 calories/mile (it's sadly less than that for me now, though), so that's why I thought yours looked high on the 2 days I looked at.

It tells me the distance and time you ran represents an unrealistic pace.?

pound vs pound, 1# of muscle burns more calories, than 1# of fat, and by quite a bit. Moral of this = weigh training to build more muscle.

Did you forget to include the seconds? For 65 minutes you need to put in 65:00.
