I'll bet nutrient restriction is a lot more detrimental than caloric restriction.
there's all sorts of crazy shit done on rats...even with severely obese patients, they'll do an extreme caloric restriction (to like 500 - 800 kCal a day), but they ensure that the full compliment of necessary amino acids and fatty acids are included (and I'd guess vitamins and minerals). Now that extreme should still have significant negative effects on performance & health, as the body is breaking down so much that some of it comes from bone and muscle, along with other physiological side effects.
What defines "dangerous"? I'm sure if you are eating nutrient dense food, you could consume 90 % of the calories you would need to stay in energy balance, and not have severe negative consequences.
just my opinion, talk to a doctor for sure. but then again considering all the questions that remain on these topics, not sure a general doc will give you the best info...if you can find someone who specializes in nutrition and is up to date in the all the research that is being done, that would be a lot more valuable
