I'm gonna jump in here
It seems like there has been a lot of discussion about carbs... I think the most important thing to remember is that the type of carb is important. So choosing the more 'complex' carbs over the more 'simple' carbohydrates can help with weight loss for various reasons. For example, complex (low Glycemic Index or low GI) carbs help to keep your insulin levels more steady after meals, which discourages the conversion of carbs into stored fat. Also, complex (again low glycemic index) carbs help you to feel more full for longer. However, I would have to agree that around 1000 cals per day is far too low and could be hindering your progress; the current recommendation from ACSM (American College of Sports Medicine) is that females should not eat fewer than 1500 cals per day.
It may be beneficial for you do look up info on the glycemic index and find some options that are lower GI to replace any higher GI foods that you're currently eating. You will find low or at least moderate GI fruits that are good options. There is quite a debate going on currently on whether fruits are 'good' or 'bad'.
Fruit is good, in my opinion. If you are going to avoid anything, avoid the processed, refined, prepackaged foods that contain sugars. Fruit has many benefits such as vitamins, antioxidants, fiber, and water that these processed foods do not contain. The tropical fruits such as pineapple, mangoes, etc., and melons tend to have a higher GI than things like apples and berries. I would recommend choosing the lower GI fruits more often and having the higher GI fruits less often.
Sorry that was a bit long, but I thought I should put in my two cents
