Giving you the benefit of the doubt on your numbers ...

1900 consumed - 1000 exercise burn = 900 calories. From that 900 calories we must now subtract your resting metabolic rate which is going to put you at negative net calories for the day. If that is in fact what you are doing, it is unhealthy.

I'm confused. Isn't being in negative net calories what we're aiming for, a calorie deficit?

Your deficit is already built into your calorie goal. Your goal isn't to be negative net calories, that would me detrimental to your health.

But he isn't in negative net calories on here unless he puts in the calories he burns through BMR as exercise.

You need to eat less calories than you burn, but you also need to fuel your body properly. The prevailing MFP wisdom is you should eat to your calorie goal, plus a portion of your exercise calories, so you get proper nutrition and don't burn out. 900 net is very low. 1200 is usually considered a minimum for females, though it might be a little lower if you are very small and older.

A treadmill run burns anywhere from 700 to 800 for an hour.

I wouldn't trust the machine, and I would keep in mind it's gross, not net.

I run about 9-10 min miles in a typical hour long session and burn 600 or less.

I suppose if I ran at race speed for an hour it would be a little more (not 800 calories), but it's much more about bodyweight/miles covered than intensity.

I recently got a heart rate monitor. What I learned: MFP numbers are not as off for most activity as people say IF you select the appropriate intensity level. The machines at the gym are way off.

How way off are they?

I am not really sure why people think that burning 1000kcal a day is impossible. When I first started running, my HRM said I burned 550cal in 35minutes.

I think you should try different things and find out what works best for you. Whether that includes not eating them back, eating some back or eating all of them back.

No one thinks it is impossible, just not as easy as some claim.

HRMs are not proof of this. There are any number of factors that can affect accuracy.

Is it just me or is everybody freaking out over a general question. All I saw in the OP was "Is eating 1900 calories a day and Burning 1000 in the gym healthy" punctuation saves lives I guess haha

I think it's the freaking out over the follow up questions I find most surprising. Simple things like hey man what are you doing to burn those calories?

No one has said that. Someone routinely burning 1000 at the gym (the equivalent of me running 11 miles a day) while eating well under what his likely sedentary burn is seems possibly overstated. In advising him as to whether his activity regimen is unhealthy, it's necessary to know what it is. If he says he's exercising intensely for 2 hours/day, then it probably is unhealthy. If he says he's walking on the treadmill at a mild incline or riding the stationary bike for 60 mins, then no, his burn is overstated but I don't think his calories are necessarily too low.

When I first started running, my HRM said I burned 550cal in 35minutes.

HRM are inaccurate for running burns when you first start running. That your heart rate goes up with what's essentially moderate exercise doesn't mean you are actually burning tons more calories than an experienced runner in halfway decent cardiovascular shape. Well more than 10 cal per min even for intense exercise should be treated with suspicion, as should anything close to 10 cal per minute for less intense exercise.

Good calculators for running burns are available and I'd trust them for calories vs. a HRM.

Anyway, OP can check his numbers by comparing them with his losses. Everyone should do that.

That’s very exciting! Good job on your efforts. I don’t have the patience for that much gym time, to be completely honest

Why 1000 calories burn in gym seems so strange to all of you?
I burn 1000-1500 calories per day in cycling according my polar rc3

It's not strange. It just takes a long time to achieve it. Most people don't have that kind of time to spend working out.

For example, I'm 5'2 and 20 lbs over weight. It takes me over 3 hours of low grade hiking to hit 900 calories burned, and that's on a good day.

The average person doesn't have 3 hours to dedicate to exercise... every single day.

I can burn 1000 calories a day with the amount of walking around i have to do, to and from work and generally around. In fact, i burn that five days a week! It's not impossible

Me too. That's a walking commute to and from work, a lunchtime walk and trip to the shops after work

If you're truly burning 1000 calories (which I'd doubt) them you should eat more to try to net your minimum 1200 for a woman, 1600 for a man

That's a big gym burn and would take me around 3 hours at a constant high intensity

I don't see why this would be impossible...I burn about 650 cals on the elliptical in an hour and a half. If I went for another 30min, I would prolly be just under 1000 cals burned.

OP: I would not advise continuing this long term. There are days where I eat 1600 and burn more than 600 putting me under 1000cals but this is not on purpose. When I am being more conscientious about it, I try to end the day with no less than 1200-1400 cals net. Less than 1000cals long term could be hurting rather than helping.
