So I took a look at the study (I normally would not because animal studies are not all that helpful and it’s not reproduced and only covers 150 rodents, so not great to begin with, certainly not newsworthy)
Taking a look at their method I noted the diet they used… macros were fine but when I looked up the provider of the premade diet I noted they do not use animal fats, so what sis they use?
Casein 173.3 +
DL-Methionine 2.6 + Ketogenic
Vegetable Shortening, hydrogenated (Crisco) 586.4 +
Corn Oil 86.2 +
Cellulose 87.97
Vitamin Mix, Teklad (40060) 13.0
Choline Bitartrate 2.5
TBHQ, antioxidant 0.13 +
Mineral Mix, Ca-P Deficient (79055) 20.0 +
Calcium Phosphate, dibasic 19.3 +
Calcium Carbonate 8.2 +
Magnesium Oxide

So to be brief, they fed mice (wrong species) a diet of 90% Chrisco (wrong diet) for 3 days… and then declaired that keto might cause diabetes. ( I am sure there is so much more wrong with this but that, I feel is enough to totally disreguard this)
