I'm curious if you recommend high carbohydrate diets at extreme latitudes during the winter when there is minimal sunlight and people are not utilizing artificially produced red/infrared light? I suspect a lot of disagreement in "the best" diet comes from the reality that in the absence of artificial light (i.e. red/infrared light) we are exposed to variable amounts of reducing versus oxidative stress depending on time of year. Eating a higher carb to fat ratio in summer (if getting adequate exposure to sunlight) but higher fat to carb ratio in winter (even ketogenic) while maintaining an adequate amount of protein seems like it makes sense for northern latitudes but I don't know that anyone has tested it beyond just recognizing it in the "eat local, seasonal, whole food" approach.
Also note that reference 3 does not support the fact where it is cited.
