Hi. You need to be careful. I'm kind of in the same situation, but now I'm 34, and my metabolism has slowed down to the point where I was gaining weight at 600-800 calories a day. I have upped my calories to 1450 a day, and it was really hard at first, but I am actually feeling better, and have more energy. When I was your age I did the same thing, rarely eating, but not because I was doing it on purpose. I was very busy, working all the time and a single mom. I only weighed between 85-100. But believe me, IT does catch up with you Big Time, so better to fix it now. As you eat more calories (good healthy calories) you will be able to eat more food more often, it just takes time. I am a good example of what to expect if you don't start eating healthily now.

Yeah! That's similar to what happened to my mom too, she was very thin in high school until it caught up to her as she aged, now she can't seem to lose weight at all. I eat pretty healthy, I'm a vegetarian and don't care much for greasy foods or sweets. I eat a lot of veggies and eggs, most of the foods i like aren't very high in calories which is a problem. Thanks for your advice and encouragement!

start eating more calorie dense food items, there are little things you can do to add calories to the food you already eat, like adding olive oil to vegetables etc. not to go overboard but just make them more calorie dense. i love eating Larabars, theyre these raw fruit and nut bars. oh and speaking of nuts, nuts are good! add them to oatmeal. put peanut butter on your bread (the kind without trans fat /shudder) im sure a lot of people will have better suggestions lol but thats all i can think of right now.

Thanks for the insight! I'm definitely doing my research on more calorie dense foods.

I can empathize, since I find myself doing that every once in a while.  I'm also vegetarian and I typically eat vegetables and a lot of beans, which were filling but did not provide enough calories.  I also don't like sweets much and I tend to avoid pastas and breads like the plague.  I've solved the problem by adding small portions of breads/pastas to my diet (whole wheat wraps, whole wheat & vitamin enriched pasta, etc.) a couple of times a week, adding olive oil to my salads, and eating lots of fruit.  Fruit is high in sugar, but it's still really healthy and bumps up your caloric intake.  I've done things like adding fresh fruit to yogurt, adding raisins to oatmeal, adding fruit to my salads, and drinking smoothies in the morning (I prefer to make them with no added sugar so they're healthier).  Delicious, easy, and a healthy little calorie bump :)

I think the above post would be very helpful in your situation. Hope you take the advice b/c eating is fun :D Do you like peanut butter and other nuts? Those are lifesavers!!!

Yeah, i love peanut butter. I was actually horrified to find out we were out of peanut butter yesterday, and since i absolutely cannot eat oatmeal without a ton of peanut butter and raisins on it, i was very sad. Thanks for all your help, i'm finding there are a lot of foods out there that i actually like to eat (fruit, olive oil, nuts, peanut butter) that will help me, but that i wouldn't really have chosen to help up my calories on my own. I think, instead of adding calorie dense foods i was trying to just eat a larger serving of things i normally eat. This was wayyyy too filling, but as each day goes by i find new foods to add and it becomes easier to add more calories! So seriously, thank you!
