Gotta weigh in here now cuz my main fellow headcase man Ceph is in the house now.
Keto did these things to me (and when i say keto, i mean anabolic diet-cheese, beef, full fat anything, oils, butter, green veggies and no carbs but maybe once a week). I did this for almost 8 weeks with no change in body comp or muscle growth.
-unpleasant personality
-Sever brain fog (to the point of not being able to grasp words i needed to use from my head, like would freeze)
-lipids all over the place (high as shit), triglycerides higher than when i was eating balanced diet (was still doing some heart health cardio)
-breath smelled awful
-overall uncomfortable with body, didnt feel good
-bp was still semi high
-weight stayed same, and my wife even commented that i wasnt looking as good (dammnnn!)
-social outings with wife or friends became a hassle (thong, why are u not eating potatos), wife giving me dirty looks for not being a normal human like everyone else (for most anti social, always single, getbiggers this wont be an issue)
-not possible as a lifestyle, as much as you read or hear people say otherwise.
