It's not that it doesn't make you leaner, metabolically healthier and generally all round better looking naked.
This is more of a PR thing. What's happened Paleo is that the crew that once was Robb Wolf and a select few beating their very knowledgable drums in solitude has now gone global - big time. The crew are now a crowd and with that comes dilution - of clarity.
We have always been very careful to cross check (and typically delete) any references in our movies to Paleo (you won't hear it in Cereal Killers 1 although you will in CK2 - Run on Fat) for the simple reason that it is not clearly defined and/or understood in the minds of the masses. Heck we're not even sure where it begins and ends sometimes!
Until now that is.
"Paleo is macro agnostic, focuses on food quality, sleep. movement, gut biome." Robb Wolf
The thing about Paleo is that it doesn't have to be low carb but many just presume it is. Wolf's shoot from the hip tweet just brushed that all aside and added some double cream on top (wait, make that coconut cream to keep it strict Paleo) for good measure.
Sure, Low Carb/ LCHF and Paleo share some common ground, but low carb/LCHF needs a definition as tight as Wolf's. Right now there is no firm Scientific agreement on what the precise macro nutrient breakdown should be in a LCHF diet.
That's important for research, guidance and (hell yes it actually matters - a lot) PR.
