But the difference is that he says he eats keto, yet needs fiber to manage his blood sugar and insulin. That’s not really keto.
Yes, I’ve eaten 100g+ per day of carbs and also never got a zero on my BHB, eating 2 days worth as a test. (What I did get was hunger, being tired, sleepy at 3pm,etc., because one day I ate 100g of carbs when I did not exercise. That was what I used to get all the time when eating carbs, and I don’t like those feelings.)
But what he says is unreasonable. He says that people eating carnivore have fantastic blood values like fasting insulin and other markers…but carnivore is bad because we don’t know of any carnivores that are 100 years old. And, epi evidence indicates we should all be eating whatever the “blue zones” eat.
I am not advocating for everyone or even anyone to eat carnivore. I don’t think most people need to eat carnivore. But your argument CANNOT be that people eating carnivore look and feel great and have great blood metrics, but carnivore is bad for you. This is illogical.
You’d at least have to toss in high LDL or … something. Anything. Throw us a bone.
What I think is happening – reading between the lines – is that D’Agostino believes that plants are “good”, as is “fiber”, and so, by definition, carnivore must be “bad”. But that can’t be your argument. Show us how people who don’t eat plants are being negatively harmed.
I can see that plants can have some value. I myself am taking tumeric/curcumin pills, and black seed oil. But nowhere will I argue that someone eating only meat and not taking that or not eating other plants or not eating fiber is killing themselves.
And I know that some people like “fiber”. I can eat small amounts of “fiber”. But if I eat too much fiber, say too many salads in a short time period, all heck breaks loose for me. I am therefore on a low fiber diet.
But nowhere will I argue that others shouldn’t be eating higher or even high fiber. If fiber does not cause constipation for you (as it does for me), maybe you can eat high fiber? I’m also not going to say that someone eating “zero” fiber by eating all meat is eating a bad diet.
And that’s basically what it appears to me D’Agostino is doing.
Edit: While I’m on my rant, he seems to say that people are losing weight on a carnivore because they are in a “calorie deficit”. While I could have plenty to discuss there, why does no one ask “Why?” He’s supposed to be a scientist. Wouldn’t the first question you ask be, “Why?” Why are they in a “calorie deficit”?
I’m testing allulose now, which is supposedly causes GLP-1 to be released. I think it does cause lower hunger, at least sometimes. (I haven’t figured out a dosage level, or how long it takes to work.)
But what if carnivore works for losing weight because it affects hormones? Or provides more protein? Or provides more satiety due to nutrient density? Or something else? Or a combination of these?
Any “scientist” who chalks things up to a “calorie deficit” without more thought, isn’t a scientist in my mind.
