I’ve not tried sous vide steak yet - but somebody stop me! Haha

Meat has micronutrients. Read through the Zero Carb / Carnivore subforum

(Derek I. Batting) #89

Does an all-meat diet cover all macro and micro nutrient needs as well as enough electrolytes to meet the demands of someone in ketosis? Not to nay-say or anything, I just have questions.

Biotin- egg yolk
Folate- eggs
Niacin- beef, tuna
Pantothenic Acid- trout, eggs, pork
Riboflavin- eggs, turkey
Thiamin- trout, pork
B6- Tuna, pork, beef
B12- shellfish, beef
Vitamin A- liver, tuna
Vitamin D- trout, roe, eggs
Vitamin E- shellfish, trout
Calcium- sardines, mozzarella
Magnesium- mackerel
Phosphorus- Salmon, beef, pork
Potassium- Salmon
Sulfur- eggs
Chromium- fish, beef, turkey, eggs
Copper- oysters
Fluoride- seafood
Iodine- seafood
Iron- oysters, mussels, beef
Manganese- trout, mussels
Selenium- oysters, tuna, beef, lamb

These aren’t the only things that contain micro nutrients but some.

And will you take vitamins/supplements as you usually do, if you usually do?

Can we quick find a researcher to compile the data for this study and then if the results are interesting a more formal study/trial could be done, and we can get results published? I would certainly sign up to be a guinea pig for that kind of study!

This is the post that piqued my interest. I have it bookmarked for further reading, a number of links are included in the post.

My n=1, I followed ZC for 18 months about 15-years ago, felt amazing without supplements but quit because I listened to others and feared I was doing long-term damage… I didn’t listen to my own body. I’m 21-days into my latest ZC run and feeling awesome.

I will consider this. It depends on what I can stockpile over the next month. I’ve really noticed that the cuts of meat around are pretty lean. And I’ve only noticed cuz of making jerky and choosing between lean cuts.

YES. Salt is definately not a spice. It is necessary for life.
And I will be taking my usual supplements. Yes.

You guys are after my own N=1 heart!

Okay – can I talk you guys into doing some blood panels throughout this experiment? You’re making extremely valuable data throughout that could be super useful to the low carb community – especially in regard to zero carb.

I can get you a great price though my doc (John Edwards), but you’d need to PM directly.

Also, while I’m adding unsolicitied advice ( :smiley: ) – please consider my food logging protocol as it allows for an ironclad auditing trail via photos. Anyone curious abour your results (not necessarily in a bad way) can have a solid, time stamped means of reviewing it. http://cholesterolcode.com/food-logging-protocol/

Once again, thank you guys so much for doing this! I’m excited to see how it goes.


Photo log on this forum could be considered robust too, perhaps? I do this with the “32 day ZC variable protein experiment” I’m currently doing, like here:

32 day ZC variable protein test

This is evidence-based protocol, maybe?

(Genevieve Biggs) #98

I’m down.


(8 year Ketogenic Veteran) #99

Not even a tiny bit concerned. I did 7 months of animal products only (no plants) in 2015 which was mostly beef steak and ground beef, had a full blood panel at month #5, and had zero deficiencies for all electrolytes, minerals, etc.
Steak for 30 days will be a piece of cake… eeerrr steak. Lol


Here is some info I think is important to review regarding effects of too much protein in daily food intake. Please recognize that I don’t mean to stir up any controversy or alarm, or even discourage participation in this test. In fact, I have signed up for it, too.

My main objective here is to point out the difference between “lean steak” versus “fatty steak” eating. Surely, not everyone in this testing group can afford ribeye and waygu steak each meal. And my concern rises from the potential that someone will consume cheaper/leaner cuts, like cube steak, eye of round, minute steak, etc (which contains approx 5% fat). Furthermore, this test has an additional criteria of cooking without oil (grilling, dry pan fry, boil, sous vide, poach, steam, etc) which limits any addition of fat to lean steaks.

There is a condition called “rabbit starvation”, or protein poisoning, which is described as eating too high amounts of lean protein. I’m not a fan of wiki, but will post the rabbit starvation link below, in case you want to read further. I would advise all participating in this test to perhaps consider the fat content of the steaks you will consume during this test trial.

Here is a quote from the wiki site, describing rabbit starvation:

“Symptoms include diarrhea, headache, fatigue, low blood pressure, slow heart rate, and a vague discomfort and hunger (very similar to a food craving) that can be satisfied only by the consumption of fat.”

No worries with me @Fiorella
I need the fat for fuel.

I’ve done this before. I need a lot of fat on the steaks.

If I don’t buy a ribeye, I’ll be buying a chuck steak. Both VERY fatty


I’m absolutely confident that this test protocol is safe. Just want to put the info out there, in case someone only chooses low fat steaks. You never know…perhaps there is a potential for that to happen? I dunno. Your steak options (ribeye and Chuck) are great fatty choices.

(8 year Ketogenic Veteran) #103

Well, Donna and I know better. Hopefully no one does this challenge unless they carefully have done their research…

Your scenario reminds me of the nazi-ish facebook groups that plagued the 2KetoDudes Facebook group with their fat fearing high protein dogma. Maybe they’re all poisoned rabbits? This would explain some of the illogical behavior…


Yeah, I get it. And please accept my apologies if I should not have put this info out there. Please understand that my post came out of genuine concern and compassion for people’s health. If someone thinks they can eat lean steak for a month and get their fat from the “Krispy Kreme they ate many years ago” they will possibly make themselves very ill. I’m participating, so for sure I have confidence in this test.

(8 year Ketogenic Veteran) #105

For what? I wasn’t inferring YOU were a nazi-ish fear the fat/high protein ketoer,

I am SO glad to be rid of that dogma…


No worries.

You are right, the anti-keto nazis lurking out there do find ways to poke holes in everything.
