Why am I not loosing weight?

How long have you been trying to lose for without losing anything?

What is your weight, height and sex?

I highly doubt that you burn 4000 calories a day.

2500 would be around your TDEE for a retail worker with your stats.

If you are not weighing your food you could be under estimating the amount you are consuming.

Eating more is not the answer if you are not losing.

How long has it been since you lost weight?

I think you are doing everything right and you will start to see results soon. It takes a few weeks to start and many months to complete. It's a long journey that you must take step-by-step. Don't we all wish it could be otherwise!

In a nutshell: I think that Fitbit overestimates the calorie burn for routine activities but does a pretty good job for sustained walks or runs.

Details:

I never believed my FitBit calorie estimates and I eventually un-linked the accounts. I still found the fitbit to be useful to tell me which days were more active than others. I also liked the sleep features. But I think it consistently overestimates daily calorie burn. My advice: don't have Fitbit linked to your MFP profile.

Not to worry! You have an active job, and the formulas for daily calorie needs are very good, including the one MFP uses. Adjust your "How would you describe your normal daily activities?" setting to either "lightly active" or "active," depending on how many days you work (if you work 5 days, I would use "active"). This covers your daily activities including work.

You can add in the calorie estimates for your workouts, using the Fitbit app, on the days you do them. These are pretty accurate.

Although I now weigh considerably less at 148lb, I don't think I ever had a Calorie burn of 4000 without a lot of purposeful extra activity even with my 20000+ daily step count.
I can get a 4000 Calorie burn for the day, but to put it in perspective that would be on a day where I run a half marathon (gives me 1500 Calories by itself). Or on a day like Tuesday will be, where I do the school run, run to the gym, have a 30 min PT session, then 45 min Zumba then walk home, then in the afternoon I do the school run. In the evening I walk down to the gym, do a 45min Insanity class, run uphill to another gym and do a 50min Boxercise class. I generally get somewhere around 35000-40000 steps on a Tuesday.

I wonder how long you've had your Fitbit for? I found mine took around a month to get to know me and give more accurate Calorie burns. Still if you really are eating 1700-1900 Calories with that many steps you should be losing some weight. Maybe invest in a set of scales and give weighing every single thing that passes your lips a try for a couple of weeks, you may be surprised at just how much you're actually eating.

I have the fitbit charge 2. I weight and measure about 90% of my food. I'm am 5.5 242.2#. Is it possible that if I truly burn 4,000 calories and eat less than 2,000 I am not feeding my body enough. I've been working with dietitian and I watch my Marcos. I was wondering if any one has ever had this problem?

Usually if you're not losing weight you're eating too many calories. I'm personally not a big fan of fitbit's, they tend to overestimate steps (in my opinion only) and tend to give you way too many calories. I'd suggest putting it in a drawer for a month, use your phone to count steps (most phones will do it), weigh 100% of your food, use accurate entries in the database (IE: don't choose an entry because it's the lowest calories, choose it because it's been verified), only give yourself extra exercise calories with purposeful exercise, not steps. CICO works, and if you're not losing or gaining weight over a long period of time then you are eating at your maintenance level.
