Kinda, though not quite as you're imagining.
When you go in to the set up area of your fitness tracker, you can set how many calories you burn in a week. With this information (as well as the info on your weight, gender, how much you want to lose, how long you want to take to lose it), SparkPeople gives you a calorie range to eat. Setting it so that you burn more calories will give you a higher range to eat. It's very important to accurately set up your fitness calories so that you're getting a range that will fuel your body - not eating enough can hinder you as much as not eating too much!
Because your trackers already account for the calories you're burning/going to burn, it's important to not "eat back" your calories like you do on other programs. Instead your extra calories are spread out through out the week. Make sense?
