N=2 10+ years of ultra low carb diet, but not quite as high fat as the study (obviously a greater percentage of protein). My BMI has been ~18 and I've been a runner my whole life, but (like my father), had neuropathy and 'fuzzy' vision in my 30s, and eventually found out that I was glucose-intolerant with large 'spikes' in my glucose levels after meals with carbs. Two weeks after cutting out carbs, vision fuzziness went away, and pins-and-needles subsided (although I still can't tolerate heat or cold in my feet). Never looked back. Never went on any drugs, running is slower, but can last much longer. Don't really feel hungry - just eat to my activity level and snacks. Eating is simple - if it has more than 2g of carbs per serving, then I don't eat it. Only supplements required are chlorides: sodium - that's easy, potassium - from NoSalt, and magnesium - an occasional capsule.
