How much damage has been done...? help please

    So this summer i decided to start dieting but i think i went a bit overboard...i was trying to count my calories but didn't use calorie count i just estimated and guessed i was having about 700 calories a day, which at the time i didn't realize was so bad for you, and basically starvation mode. On top of that i was working as a server and constantly moving about 4 hours a night 4 shifts a week. I realized after joining this site that i was really only consuming about 300-400 calories per day for the past month and a half or so.
How much damage do you think has allready been done?
And also i'm trying so hard to eat more now, trying to get up to at least 1000 calories/day but the most i can get is 700. And i know that some people are probably sick of people complaining about such unjust things when they are having trouble overshooting there calorie intake, i just really would like help. It feels like i am forcing the food down by the end of a meal, like i feel full and tell myself to keep eating just for the nutrients that is coming from the food, but i still can't manage to eat enough. Does anyone have any tips for food that is low in fat but still high in protein and can help me?
Thank you so much, it would be greatly appreciated =)

#1 thing...at least you know there's a problem.  A lot of people either don't realize there's a problem, or do understand they are hurting their body...but won't do anything about it.

I'm not a doctor so I can't give you any real medical advice, but I am kind of in the same situation.  In the morning I try to eat a full breakfast, but I can barely finish one serving of yogurt before I feel so full I'll be sick, the same for lunch, I have hard time eating a full meal. 

The best advice I can give you, is what has been working for me.  And that is, take it slow.  Allot yourself a longer amount of time to eat.  I find that when I eat slower I don't feel like I'm forcing the food down by the end of the meal, and when I'm not rushing I'll actually finish it all.   And when I say slow...I mean slow...it can take me a half an hour to 45min to eat my breakfast.

The foods that have really been working for me is the yoplait low (or no) fat yogurt.  I have yogurt and cereal for breakfast almost every day with a glass of orange juice.  I also LOVE chicken (not fried of course).  It's a good source of protien and if you cook it the right way there's not a lot of fat.

I hope my ramblings have helped at least a little *shrug*

wow sounds like we eat the exact same thing, for me my breakfast is one large apple cut up in 100 g of fat free vanilla yogurt with cinnamon sprinkled on top, its amazing! but after i eat it i just feel full and dont feel like eating until like lunch, but i know im suppose to have like 6 meals a day. i also have chicken for dinner but i have to force down the last half of the chicken breast, like i can only eat half of it and some veggies and than im stuffed, ill try taking more time to  eat and hopefully that will help =)
thanks

Well kaym22 is right.  At least you acknowledge that there is a problem.

I suggest eating more calorie-dense foods.  Instead of an apple and some yogurt (which prolly is about 150 calories)  try some peanut butter on toast.  Peanut butter and nuts are a good fat source and can raise your calories without making you feel more full.

Other good things are avocados, olive oil, any kinds of nuts (especially almonds) and try to stay away from the lower calorie versions of certain foods.  For example, eat regular yogurt instead of low cal.  Eat 2% cottage cheese and milk instead of the fat free, etc.  Dont forget that you do need some fat in your diet for your body to function correctly as well as to absorb vitamins and minerals.

Bottom line is take it slowly.  Slowly try to raise your calories and slowly try to eat more

I just want to jump in and echo what peaches said. Eat more calorie-dense foods and make sure you are eating some good fats like those found in fish and nuts, olive oil, etc. Many of the nutrients that you need in your body are fat-soluable, meaning that you can't absorb them from your food unless fat is also present. You could end up with vitamin deficiencies if you don't get enough fat in your diet.

Also, coming up from a 300-400 net calorie diet, take it easy and slowly increase your intake. You don't want to shock your body by adding too many calories too fast. Just ease yourself up to a healthy intake of at least 1200 net calories per day.

If you can't manage to up your cc by eating then try to do so by drinking by drinking juice or if you're desperate some Pepsi.

thanks so much =)
i love nuts so im going to go and buy a huge bag of almonds and just like munch of them
and pb on toast is always a good choice and doens't make me feel that full, thank you guys so much

If you are having trouble eating your calories, try drinking them. Pepsi probably isn't your best choice. I would suggest a vitamin enriched drink like Ensure or Boost.
