I think its the fat mostly on the carcass after they pull off the hide.  They can slice slabs off depending on how much fat the animal is carrying.

There are pitfalls on the Wai diet.  I tried it some years ago.

Fat and sugar glycate, and and cause problems on a cellular level.  Read about it.

Fruit has high amounts of fructose, can cause fatty liver. 

Moderator back then had to consume extra white sugar mixed into his orange juice to stay full of energy.  Should tell you something.

So, pay attention to any signs, and, they, like many deficiencies, can take a while to evidence.

glad to hear others chime in about fat and protein...  Early man Most likely had availability to plenty of fat.   I have availability also to plenty of fat, and choose to eat plenty with my meat.  My guess is that most would choose the same when the fat is a tasty as the fat I get or the fat that came off of a large animal after a fresh kill back then.

 I would love to be able to read more data on the balance of sodium as I've dropped salt now for maybe a month and do better with out it.  I know that Paleomedicina folks do you salt, but then they're not raw.

I'm guessing you didn't eat enough fat. ( especially if you relied on expensive marrow bones for fat )   I recently cut back on my meat consumption and increased fat.  So easy to think we need large portions of meat when reading other's accounts.  Also for the last two weeks have cut out salt.  No longer have problems with water not quenching my thirst.  At first everything was bland.  But after a few days the taste buds reignited.  Feel much lighter as a result. 
    One experiment you can try is to catch your urine and look for sediment, which in my case appeared to be uric acid crystals, as a resultant from excess protein.  Let it sit for a few hours to see what settles. 

My experience with muscle testers is that they have been bogus.  I'm sensitive enough to know when someone is pulling down on my arm and when someone is faking it.  The only way to truly muscle test is to do it blind folded and repeatedly.  Which means you don't know what your holding nor does the person pulling down on your arm. and then to do it ten times, alternating with other foods. 


    You have a bacteria in your mouth that is feeding on the foods you are eating.  Their excrement is acidic and destroying the enamel on your teeth.  They are also forming colonies under your  gums and proliferating every ten minutes. 
   Find out either what is allowing them  in the first place  (immune system ) or take away their food source. (Green apples for instance and the remaining sugars in buttermilk that haven't been converted into lactic acid) or up you oral cleansing to where there is nothing left for them to feed on.

dairy, besides being low in mg. is full of sugar or acids if fermented.  Always rinse out your mouth with salt water after consuming.  Get fuzzy floss and use daily.  Every week make a paste of baking soda and coat the fuzzy floss with it and floss under the gums.  Mild abrasive yes, but will clean very well.  Get soft bristle tooth brush and brush at a 45 degree angle gently, working the bristles under the gums.  Look up MMS and buy some to brush teeth with. 
    I've been close to zero carb for years now and carnivore for over a year, teeth better than ever.  There's no sugar for the bacteria that cause dental carries to feed on.  Keep your mouth clean throughout the day, especially your tongue. 

Yes,, and if you care to try,,  finely shred or grind  coconut meat so that you can such the 'milk' out of it discarding the pulp..  You'll most likely notice, as I did, that it's only palatable for only so many mouthfuls.   So easy to take in more when it already sitting in a cup ready to swallow down.

most here could use all the acid their stomachs produce to digest good portions of either cooked or raw meat.  To include vegetables, either cooked or raw,  is only going to neutralize to some extent the acidity of the stomach.   If you want to eat vegetables, eat them sparingly with protein, or as a snack or separate meal, or with some easily digestible proteins like aged cheeses.
  It's our acculturation that keeps us eating our meat with veggies ( besides our desire for taste or carbs like potatoes etc...

eating raw grass finished liver as I write.   I Think that if you eat it piece by piece, alone, not seasoned, your body will tell you how much it wants.

stir it with a clean spoon or fork etc..

oxidized rancid fat.  mice don't naturally eat fat, rancid or not.  it's the resultant inflammation that causes the harm.

large particles, yes, Benzene, no.
