If everyday were like today..you'd weigh.....

Your body has hit a plateau. That's normal for everyone. If you've been eating the same foods or doing the same exercise program, you may just need to change them up a bit to give your body a new challenge.
Don't get discouraged. According to your tracker, you've been doing great so far. Don't let this break in progress ruin all the hard work you've been doing. Keep it up and get creative. Good luck!!!

40+ days the scale didn't budge. I worked out, I eat very well, within my goals, I ate back most calories when I worked out blah blah blah and nothing. NOTHING. I was at my wits end, when holy shizzballs I finally lost a pound this week. I keep thinking its because prior to packing on 20 pounds I was in very good condition (runner) and so its taking me longer? I have no idea, age, metabolism, muscle gain whatever. VERY VERY frustrating

DITTO but today I clanged my calorie intake from 1650 to I think 1710 so we will see

You are taking it too literally lets face it how can it know individual metabolism rates etc it is only a guide. MFP has been great for me as a check on calories taken and burnt and it is a great monitoring tool. That said I have also carried out changes of routine such as eating back / not eating back ex cercise calories (some or all) and by doing this I have lost an average of 1.8 pounds per week top loss early on 3 lbs lowest .5 lbs. However my routine may not suit you you have to find your own system. Also why weigh daily? I weigh once a week and where possible same day same time. Sometimes I cannot so wait until the next day same time.

This has not been a diet for me it's been a lifestyle change I still eat things I like, I still have an alcoholic drink but in smaller portions and smaller quantities. I still eat Chocolate daily and when I get to my target (11 lbs to go) I know what I can and cannot eat to help maintain. My Wife has also lost 32 lbs doing simular excercise and portion control she has had 1 or 2 weeks occasionally where she has not lost weight but hasn't got downhearted.

Hope this helps and good luck

I know this may sound counter intutive to what you have been doing but you may need to adjust your calorie intake up. You may have reached a plateau. If you are resticting your calories to a low amount, your body will adjust to that level and be able to survive and holds on to fat. You actually have to eat more than you think in order to lose weight.
I had the same issue a couple of months ago, that's why I joined MFP. I was working out eating what I thought was the right amount around 1300-1500 calories. When I actually started tracking my calories vs excercise I found out I was not eating enough. I upped my calories to 1800-2000 and have lost 10lbs. Just an
idea.

Wow..that's incredible. Mfp has my caloric intake set at 1200 cals per day..I'm usually under by atleast 100cals...afraid to go over too much, because I'd seriously give my scale a beat down if I saw a gain..instead of a loss. Confused...and really pissed!!!

If you are also excercising this 900 calories a day is not enough, is that your net calories? This is how a friend of my put it "The rule of thumb that I understand is that 1200 calories is the low water mark (if you will) that you want to stay above. Anything less than that and your body goes into the 200,000 years of training it's had. In short it says. Ok, we are not eating, there must be famine heading our way, it's time to store fat. You can actually get fatter and gain weight by eating less! Amazing. I'm over simplifying that, but you get the picture".
