Congrats you should be closing in on the end of withdrawal phase if you aren't there already 

 Which is more difficult? 

 You’re going to love it!! I follow a carnivore diet mixed with some fruit as a treat! Stay the course! 😎 

 Better get some Metamucil. 

 So am I right in thinking that the commonly accepted definition of a carnivore diet is just a rehashing of a keto diet? 

 Diet doesn't work limitary. 
Dietary needs or health can be understand out of a evolutionary perspective. It's praxeology. 
We emerged at the south east African rift and migrated along the sea to Europe. Cold periods in evolution forced us to get our food out of the sea We ate lots of fish during our evolution. 
That's why the biggest nutrition deficiencies are omega 3 and iodine nowadays!
Just do the things human used to do in evolution. Stay outside in the sun, grounded and eat the things that have been around regionally for the last 100000 years.
Eat seafood

 I'm having fun limiting my diet, I'm interested to see the results. 

Not sure what the optimal diet for me is, I'm sure if I just continued doing what I was doing I'd be fine. 

I'm 5 foot 6 145 pounds with a six pack and a 27 minute 5k time past the age of 30. 

I'm allergic to shellfish.
