Cutting down to just essential amino acids and other essential nutrients like some select fatty acids, cushions, and minerals, isn't that hard if you can avoid carbs from getting advertised to you. Even a non-optimized protein source like eggs easily offers ~500kcal/day at sufficient protein levels, and sustained keto doesn't really include hunger feelings. It's not particularly healthy, but if the only way to keep up a significant caloric deficit is to see the rapid results of this kind of diet, it should still be healthier than morbid obesity.
