Keto is not a miracle thing. For some you health gets worse. Like myself.
Did strict keto and my body did not like it.
My body needs a normal carb based diet.
My t did not change. Even got worse since my health got worse on keto over 6months.
Out body chemistry is different. Keto works for some,for some it does not.
Not talking about t now.

Its worth trying as most other things. But needs to be followed. If you cheat you need to start over because you will get out of ketosis state.
