Under calorie goal everyday

why don't you just eat some extra food?

Me too.... I am happy with this but will it slow my weight loss down?

Yes, but this wouldn't be "just to eat", it would be to fulfill your calorie requirement.

I don't think she was asking how to "fix" not eating enough calories. She was asking if it was unhealthy.

Are you not eating those exercise calories back? I used to go 300 - 400 under my goal of 1200 pretty frequently and it took 3 months but I hit starvation mode and haven't lost a pound in over 2 weeks. I'd suggest trying to eat back those calories. It's pretty easy to make back 500 calories too. A cup of oatmeal and a large (6oz) banana is ~450 calories already.

It can be unhealthy if it causes your body to go into to starvation mode. U will normally know this because u will plateau in your weightloss. If u r still losing than u r probably fine. Try eating small high calorie foods like nuts or adding some olive oil to other things.

It can become a problem if the resulting deficit is higher than what your body is comfortable with, and if you're not getting good nutrition.

I'd recommend reading the following threads that discusshow MFP calculates cal goals, metabolism and why it's important to fuel the body properly.

I have set my calorie goal to 1500 calories but never seem to meet it. I know it's ok to be under but I'm under about 500-700 calories quite frequently. I've been exercising everyday so that plays a factor but I was wondering if this pattern is unhealthy.

If your target is 1500 and you are falling short by 500-700, that means you are eating 800-1000 calories a day. Let's assume you burn 300 calories per workout. Your NET is now 500-700 calories a day. That is NOT enough. You are not giving your body the fuel that it needs to survive. Read the links in my signature for some more detailed explanations but the bottom line is, yes, that pattern is unhealthy. You NEED to eat more!!

You are not giving your body enough nutrients. You are starving your body, which is not healthy in the end.

I only eat when I'm hungry. I try not to eat just to eat.

See the problem with this is a big part of the reason many are on MFP are to retrain themselves to eat- we tend to build bad habits of over eating, our bodies' signals for when and what to eat become kind of screwy. It can just as easily NOT tell you are hungry when you need food as it can tell you to eat when you need nothing.

It is pretty unhealthy to be that far under and it will slow your metabolism (throwing of the calculations of MFP and other similar sites in terms of how much you need to eat to lose) and make it more difficult for you to lose .

I would say train your body first- plan out what to eat and when to make sure you do get to enough calories. And then when you've trained your body back to a healthy place and healthy habits, THEN listen to your body's hunger signals. But to depend on them after however long of messing them up, I just think that's expecting a lot from your body.
