I don't know how unique I am, because experiences much like mine (and even more extreme) are quite common on low-carb and insulin resistance forums just on this website (and even more so on other low-carb and autoimmune forums).
I'm not aware of any research that has done controlled studies of the metabolic differences (closed system research of weight loss is so rare, no doubt because of the inconvenience and expense. With self-report studies you're always dealing with the uncertainty of subjects'accuracy in self-reportingtheir caloric intake).
In my own experiments, I paid closest attention to the calories-in portion of the equation, but not the calories out, but I did notice some interesting differences that were notable regarding the "calories out" part of the equation (but these observations were subjective. I'm confident in the trend, but I don't know the degree of the difference).
On low-carb:
I sleep less, but feel more rested (there routinely was at least an hour difference).
I have more energy, and am I'm sure, as a result are more active.
My body temperature significantly increases (my "normal" body temperature is quite low. Under 97 isn't uncommon, though average is low 97's. On sustained low-carb, my average body temperature was much closer to normal often over 98.0)
I have fewer flares of my arthritis, fibromyalgia, lung/sinus issues, and skin issues (which also as a result are likely to improve my functioning, and therefore my activity level). When I feel great, I do tend to push myself to do as much as I can, just to take advantage of the opportunity (I'm on disability and as a result of pain and mobility issues, I am often forced to be more sedentary than is conducive to sanity).
I was diagnosed with an autoimmune disease attacking my sinuses, lungs, nasal cartilage, joints, and skin. Since reducing carbs, I've gone into (suspected) remission. Of course the steroid(prednisone) treatments could have caused the remission. I suspect diet playing a large role, because when I have relapsed into a high-carb diet (for example this past and last Christmas), I have reoccurences of the skin and respiratory issues.
Though my belief isn't based on fact, because there just hasn't been enough research to prove whether I am unusual or the norm, I do believe that I fall on the extreme end of the spectrum, but I don't think I am at all unusual. I've heard too many stories similar to mine. It was actually the autoimmune research with low-grain and low-carb diets that persuaded me to try low-carb eating. The more reading I did on the subject, the more I'm convinced that there are far greater differences in carbohydrate/gain metabolism than is commonly thought. How many people are affected, and to what degree, I don't think the research to this point can say.
We need more closed-system research (where calorie intake and calorie expenditure can be accurately monitored), but closed-system research is expensive and inconvenient. The research subject pool is also limited, and not representative. The "average" person isn't going to be able or willing to take off work, and leave their families and lives for several months to live in a lab-setting.
