Can this really be accurate?

So... I hope you guys can help me out. I have just gotten my Fitbit. It says that I burned 2600 kcal today and that I can eat 2300 kcal. And Im on a 500kcal decifit program. It doesnt add up? Its only 300 calorie difference.

Also. I have counted calories the last year and I have eaten ca. 1700/day with no weight loss (yes I excersice almost every day) but also no weight gain.

If I eat 2300 calories I will defenently gain weight. I haven't eaten that much on a regular day in years.

Couple things: the Fitbit counter is saying you can eat that many calories because it is calculating you total estimate until the end of the day.  Yes, it may say you burned 2600 calories at the time of your post, but your body will continue burning calories until the end of the day (and after too).  And if you decide to exercise, the amount you can consume will increase,

Also, remember that though the number may not be reflected on the scale, if you are eating nutritiously (assuming you are), and exercising, your body will respond.  Not all weight loss is linear.  Trust the math.  I was skeptical too at first with the high number of calories burned Fitbit was giving me, but I decided to eat more anyway and the weight has been dropping a lot lately.

Without knowing your BMI and exercise level, it's impossible to estimate your daily calorie allowance. I'll take a wild guess that if Fitbit's advising you to eat 2300 cals, you're quite possibly in starvation mode at 1700, which would explain your problems losing weight. Eating enough is important to your long-term weight stability, because your body will adjust your metabolism downward if it's not getting enough proper nourishment.

Start with a BMI calculation and go from there.
