A ketogenic diet increases testosterone in resistance training men: https://www.ncbi.nlm.nih.gov/pubmed/28399015

A ketogenic diet does not deplete glycogen, which means there's adequate glucose supply (contrary to what the article implies about that): https://www.ncbi.nlm.nih.gov/pubmed/26892521

OK, that's it for that, but there's lots more I didn't even click on. Ima say the article is a big fat lie. Let's see, men will want to increase their testosterone, ya? I mean, who wouldn't. Women will want to keep their strength up, while they cut a lbs or two total weight and a bit of fat, and build a bit of lean mass, ya? I mean, who wouldn't.

There's uber-short-term stuff (3 days and crap like that) that says keto is bad, and rat stuff too. Ima ignore all of that.

So what's the deal with libido? Lemme see. If testosterone goes up, and if strength stays where it's at, and if total weight goes down, and if fat mass goes down, and if lean mass goes up, and if there's adequate glucose supply, how does all that correlate with lower libido, hm?
