So yesterday I started what I hope to be 30 days of the Carnivore Diet, just to see if all of the health claims from people like Joe Rogan would be true for me too. I definitely need to lose about 50 lbs, cut my addiction to sodas/empty carbs and change my health.

Have any of you ever done this diet, another diet that is far removed from the Standard American Diet, or any other sort of bio-hacks and how did it go?
Hey jalanlong - my best wishes.

I have a lot of experience. Over 10 years strict carnivore. Now, a bit less strict, but probably 90% carnivore. It's been very good to me.

Just so you know what to expect, you are going to feel like shit for at least 2 weeks. Assuming that you aren't a spring chicken anymore, it may be 6 or 8 weeks. If you can manage to keep your trial going for 60 days instead of 30, you'll have a better comparison to see if it is for you or not.

Here's the killer: Your body processes carbohydrates for energy much differently than it does fat. It actually requires mitochondrial and brain chemistry changes to use fat effectively. You don't have those changes yet, and it will take a while for them to develop.

In the meantime, your body will panic. It will start searching for glucose in whatever form it can get. You can expect to lose around 10 lbs of weight in the first couple of weeks. Almost all water. Stored glucose in your body is bound with water and it will be released as you harvest it. Your liver has a glucose reserve. You may notice long periods of elevated heart rate and anxiety. That is your body pushing epinephrine (adrenaline) to get your liver to let go of the glucose in a fight or flight response.

You may lose a lot of fat because your body is ripping up fat molecules to get to the glycerol and throwing away the rest. Your piss will smell like acetone from the discarded acid chains.

You might feel fuzzy in your thinking or not as sharp as usual. The brain is a huge glucose hog, and until it converts over to ketones it won't be at 100%. The good news is that once it's running on ketones you will be sharper than ever.

Aches and flu like symptoms for awhile - again until you rebuild your mitochondria.

Your bowel movements will be all over the map the first few weeks. All of your gut flora that depend on carbs will die and leave in a hurry... likewise the volume of food that you eat will be significantly reduced, so don't expect the same regularity that you had before. Eat plenty of fat and drink plenty of water.

That's about it! I don't mean to scare you, just don't expect the transition to be smooth sailing. The change affects every level of your body down to the cellular level. The good news is that it is totally worth it. You will be in the best shape of your life and have the highest mental capacity.

Thanks for the help! I definitely have the foggy brain and dull headache thing going.

In your experience would it have been better for me to slowly ween off of carbs instead of going cold turkey? I went straight from a Standard American diet with tons of soda and empty carbs right into meat,eggs and water. I wonder if I should have tried to transition over a few weeks or if it would not have made any difference?

I've heard good and bad from both approaches. I'm a cold turkey kind of guy. Rip the bandaid off and see what happens.
I made the transition in my mid 40's and it hit me hard. I was the CTO of the company and my brain shut off for about 4 weeks. If I hadn't also been an owner, I'm sure I would have been fired :)

I didn't have nearly as bad an experience as Mark describes and that may have been because I had been dabbling off and on with low carb eating for quite a few years before I went with keto/carnivore. So my body wasn't totally shocked by the change.

I'd take the things you are feeling as good signs however. Just shows it's working.

God, this reads ilke withdrawal and rehab for grain and vegetable eaters (omnivores, really).
I don’t mean that in a disparaging way; just being factual.
I honestly had no idea.

Lazy keto here as well. I will not refuse myself a cookie or chips, for example, but our meals are mainly meat and vegetables. Sometimes some white rice.

I never drink full sugar pop, but do drink diet at times. Never really eat bread or pasta. Completely stay away from vegetable oils, except what’s in the chips...

When I go hardcore low carb, I fall to about 191. Typical lazy keto, I sit around 196. The five pounds is not worth restricting myself that much.

Joints, in general, are less achy when I go hard core. Other than the five pound difference, that is what I noticed the most. I see no real difference in energy or mood. But I was in generally good shape to start with.

In addition to keto/carnivore I have to give some credit to the fact that I retired 4 years ago for my weight loss. I think the stress of working has a lot to do with it as well as going out to lunch every day with the guys at work and then coming home to enjoy my wife's cooking for dinner.

Now I'm the cook and I can eat whenever and whatever I want as long as the other members of the household don't complain too much.

Vegetarian 30 years vegan 10. Food is a drug and it takes years to wean off the large dopamine bursts from high fat/sugar/salt/meat. You cut back a little at a time. Diet doesnt matter much tho, im ripped because i only eat once a day and walk 10 miles/week. Try coffee and tea instead of lunch.

What is your height and weight? Any other exercise aside from the walking?

keto and near keto for a at least 7 or 8 years now, (i have lost track ) no negative symptoms during the transition, lost a lot of weight, better joint health etc etc...

not being as hard core with it right now, but still avoiding the bad oils, bread and most sugar, i also stay fairly close to an intermittent fasting meal pattern...

Hey Vinny,

Let me recommend a book by Lierre Kieth, "The Vegetarian Myth." There are a lot of claims about the dangers of meat eating that simply aren't true. The book very effectively rebuts them.

Research on pre-Neolithic diets indicates that the human diet was primarily (but not exclusively) based on meat. And, that human health worsened significantly after the transition to agriculture - height and life expectancy declined, teeth and bones started showing chronic disease, and heart disease (from investigations of Egyptian mummies) became common. Fascinating stuff. Takehome is that humans are not adapted to a vegetarian diet, and particularly are not adapted to eating grains.

I used to walk 6 miles/10km a day and was by no means ripped. You must have good metabolism.
