always under my calorie goal, advice?

Well, your diary isn't visible so we have no idea what your goal is, how far under it you are, what you're eating, etc. You'll probably get better responses if you make your diary public and share more info.

1200 is really low and you aren't getting that most days. Eat more. What you are doing isn't sustainable and you may end up reverting back to your old ways. You are going to lose muscle along with fat if you continue to eat so little. Eat what MFP says. Its a minimum so if you go slightly over, its okay.

eat more cal-dense food!

Do you like avocado? I LOVE avocado and would put it on everything if I could. It looks like you eat out alot so I am going to assume you are always busy and on the run like me. You can try buying say muscle milk or naked protein smoothies and drink one as a snack either mid morning or afternoon. You seem to always run around 900-1000 in calories so you only need to bump it up say another meal of 300-400. On the avocado note, it is full of healthy good for you fats and vitamins and subway has it right now and you can add it to any of your sandwiches. Also if you switch to a whole grain bread that will increase your fiber and add a little bit more calories and cut down on your sugar which will help your insulin and can help your body let go of fat. On days you dont have time for breakfast since I see you skip it sometimes. A piece of whole wheat toast with 2 tablespoons of peanut butter and peel a half a banana fold the bread over the banana like a taco and squish a little and out the door you go, healthy carbs protein and healthy fats to satisfy and it is easy to eat while on the run Hope this helps

http://today.msnbc.msn.com/id/44523397/ns/today-today_health/t/exercise-can-curb-hunger-new-research-finds/ I agree with this article. I find when I exercise I'm so not hungry. I would suggest trying to exercise earlier in the day so that by dinner, you have a bit more of your appetite back.

it is the opposite for me. When I work out, and I always make sure I fuel my work outs by eating before hand. I might not be super hungry for about 3 hours but then I am STARVING. So I always eat a little right after and have a meal planed for later. And if I didnt eat my exercise calories back I would end up way over eating the next day. But then this is on days when I would work and then go to the gym and burn another 600-700 calories. Cant work out right now because of my back. But I dont know how exercise can curb hunger. I am sure it works for some people but everyone is different

Your calorie intake is painfully low for someone your age. Your protein intake is also very low.

Assuming you will eat less as you get older, by the time you're 40 you'll be surviving on about 3 peanuts a day.

You need to eat more. Looking back a few days at your diary, there are some days that you don't even break 900 cals.

I know the intent is to eat less move more to lose weight, but you still need to fuel your body. Keep in mind, MFP already creates a calorie deficit according to your weight loss goals. You don't need to create more of a deficit.

I would have to say eat at least 1200 in this case, and I'm not telling you not too, but if you don't make sure you consume a boat load of vegetables, I have noticed, that I cook a lot of cabbage and greens sometimes two big pots per week. I will eat it until it is gone and then make another one. What tends to happen is, because they are both very low in calories even if I eat them twice in a day, I will be full but the calories are under my calorie limit. There is nothing I can do about that, and I refuse to eat more for one when I am not hungry. This is very hard to do. I am down 18 lbs and I believe my stomach has shrunk a little causing me not to consume the way I used to. I'm not an expert and believe I was just deleted by a friend because I don't eat my 1200 cals, she cannot support that I read, but who's to say, what they feel you should eat that is just a number to me. As long as you are not hungry is the point! Sorry I sound like I am venting. Good luck.

It could also be that you are forgetting to log some things? Like for example, are you really having a sandwich made with bread, ham and a slice of cheese only? Did you put mayo, mustard, or any other condiments on it? Did you add anything to your can of tuna that you had for dinner? Sometimes it's easy to forget to add toppings etc but they do add up!

Are you without an appetite? If so, you might want to talk to your doctor.
I would also add cottage cheese, fresh veggies and fruit.
Best of luck!

I am the same way...I actually feel sick if I force myself to eat the 1200 to 1500 range it wants me to. I am almost never hungry after exercising either...I love fruits and veggies and all that jazz, but just can't seem to make myself eat a lot of well anything. I am not a big junk foodie either. I would love any advice or help too...I will change my diary to public so y'all can see it

I think protein shakes are a great idea! Like chocolate flavored powder to mix with milk. And maybe try some fruits with your breakfast in the morning and some veggies for a snack!
