Not a scientist but did some undergraduate work in biochem. The answer might be in those two observations (Alzheimer's + obesity). As I understood it in most cases of Alzheimer's there is a deficiencies in the brain- glucose pathway/efficiency and as a result (some studies think) that the brain now have to work harder at extracting the energy from pathway and spend less time on maintenance+cleaning... (plague + metabolites). Thus switching the brain to ketones(or low enough carbs) will force brain to make use of this new fuel source.(better source ?). There is definitely a link to obesity and over eating on carbs/sugar/glucose Just interesting that the two cases might be realted (Alzheimer's and obesity) disclaimer not a scientist or hippie.
