Looking for some published studies or journal articles, please

I have been looking for studies that look for negative health outcomes of low calorie intake (under 1200) in healthy adults who are not overweight or underweight. I've found studies of obese people, and of chronically underweight people, but nothing in between. I am not interested in adaptive thermogenesis, as it isn't harmful per se, it just reduces caloric needs. I'm not looking for weight loss studies, but if you know of one that documented any increased risk factors or adverse events, I'd like to read it.

So my question is this: do any of you know of any studies done on whether a low caloric intake, with sufficient protein and micronutrients, for healthy subjects with a BMI between 18.5 and 24.9, is associated with any increased risk factors or negative health outcomes? If you do, and you can link them, i would really appreciate it.

I've scoured pubmed and google scholar, as well as the web archives or the annals of internal medicine, and come up empty, but I'm sure I am missing many studies due to search terms I haven't thought of. I figured on the off chance one of you knows about a study, I'd give it a try.

Thanks
