I ignore the burning too much message because it seems to happen to everyone who is active and wears a fitbit. I have used my weekly calorie burn from previous weeks to set my "weekly exercise calorie goal". It is that weekly exercise calorie goal that influences your Spark allowance and when it posts the "burning too many calories" message.
Here is what I do, to get my Spark allowance to accommodate my activity but not inflate it too much. I haven't really figured out how Spark calculates our exercise calories, but the minutes are from our Fairly active and very active minutes on fitbit, and the calories seem to include our BMR (which Spark already credits us for).
Spark uses Harris-Bennedict to estimate our BMR, fitbit's estimate for my BMR seems very similar to Mifflin. I already know that H-B gives me 120 more calories than Miffling for BMR. So I subtract 120 + 1 calorie per fitness minute from my weekly total and set that as my weekly exercise calorie goal. I also round up to make it an even 100 type number for my own convenience. (My sedentary/bmr calorie burn on fitbit is about 1 calorie per minute--I think a little less but I don't want to mess with fractions). I don't do this every week though, I just want to get in the right ballpark so the lower end of my Spark range is what my fitbit allowance would be on a sedentary day (though you may not have sedentary days).
I know it is confusing so I will give last week as an example. My exercise calories were 4113 and my minutes were 1051. If I subtract the 120 and 1051 minutes from 2113 I get 2942 calories. To round down to 100 I would enter 2900 as my weekly calorie burn goal.
The other thing is on the fitbit food plan I enter my goal weight and choose how quickly I want to lose weight. Then I look at the date fitbit predicts I would reach this goal. In Spark, I enter the same goal weight and for the "deadline" I want to reach goal I enter the same number that fitbit predicts. This is what effects your rate of loss on Spark and it directly effects the allowance--sometimes more obviously than the exercise calorie burn goal. Setting your deadline for a closer date results in a smaller allowance than a more distant date (but it will warn you if you pick a date that would result in more than 2 pounds a week lost or if it would put your allowance too low).
I know the feeling of eating what they tell you to eat. I am walking between 2.5-4.5 miles everyday and playing tennis 5 days a week. The tennis is not high calibre as it is with a seniors group here in Fl., but non the less it is 2 hours of exercise. SP says I need to eat around 2000 calories a day and I have a hard time with that. That is more than I was eating when I was still back home and going to the gym 4 days a week. I haven't got that much into me and as a result I am not losing and as a matter of fact I gained .5 last week. I did buy whey protein and going to try and add that in between meals on those days.

If you divide up your suggested calories into 5-6 meals a day it will work
Suggest that you let SP give you suggested menus for a while where they give you a estimated number of calories per meal for a while and then make changes to it making it more your own
Not sure how many calories they are suggesting but you really can get them in
also remember that if you don't get in at least 1500 calories a day and you are putting out more than than you can put your body into starvation mode which will keep the weight on and make you more frustration
Everybody tells me that they would love to knit, but they don't have time. I look at people's lives and I can see opportunity and time for knitting all over the place. The time spent riding the bus each day? That's a pair of socks over a month. Waiting in line? Mittens. Watching TV? Buckets of wasted time that could be an exquisite lace shawl. ~Stephanie Pearl-McPhee, At Knit's End: Meditations for Women Who Knit Too Much
On a typical day at work, between actually cramming in more movement (and this is a neat trick, seeing as my knee now completely disallows stairs) I am highly active. I work in housekeeping, which means much moving back and forth, lifting, dragging, pushing carts, and the like. On a typical mid-business season, the time I spend usually results in a 1k caloric burn at base, without allowing for any of the movement that I've managed to cram in.
The problem is I'm trying to lose a few. I'd like to drop to 150 ideally. My doctor would prefer more, but as I said, my work is highly physical--it's likely that anything lower than that won't be possible with the muscle it takes to actually perform.
But I have NO IDEA what to do with the caloric estimate I get here at SP. I have never had a day where I haven't gotten the warning about my activity level being too high for my intake.
What should I do? I have no idea if I'm doing this right.
