No matter what is the name, people will keep these things… I let them. To me, keto is where I am in ketosis (so I like the name… oh when I did paleo… that name caused problems but that wasn’t my problem either), it is logical to me, it makes NO SENSE to me to consider keto only if we follow some strict rules that aren’t necessarily and maybe not even enough for ketosis…
But as I don’t measure anything and ketosis feels like not ketosis if I am not really low carb, I call my day “keto” if I am below the net carb limit I experienced as strict enough. Just like many people use 20g net/total even though they don’t know if they need it or if it’s enough for their individual case. But if someone eats up to 100g net carbs and stays in ketosis, I consider their diet keto (conditionally as I can’t possibly know if they are in ketosis. but if they are, it’s keto to me).
People love general fixed rules but our body just doesn’t work that way.
But we follow different styles of keto anyway… I am fine with using my own terminology but indeed, it can be problematic in understanding each other if we call wildly different things “keto”. If I see someone saying they eat keto, I suspect the one in question probably eat right to be in ketosis about all the time and probably eat little carbs (or they are delusional, it has a chance)… I can’t know anything about their food items as keto doesn’t ban anything and there isn’t any item that is required. That’s one thing not mentioned but people do: they consider certain items forbidden on keto (and probably many people think some items can’t be avoided). But if we just want ketosis, we don’t need to avoid carby items. It’s often a very good idea but being super strict is unnecessarily hard for many of us. I had enough of that in my one month paleo, I enjoyed I can eat almost anything on keto when I started (I already didn’t want to eat a lot of things being a health-conscious low-carber though).
So it’s clear enough to me, keto - ketosis.
Low-carb is way more vague, I never know what to think when I hear that. If I say that, I think of my old woe below 80g net carbs. If I hear from a doctor or someone with diabetes, it’s 150-160g carbs (or less but they love to use it as it’s often considered low and hard… as many people are used to even more). And some people call their keto or “mostly keto” simply low-carb.
I am a low-carber for sure but it’s not very informative.
By the way, I eat 60-70% fat but below 60 (while very rare) is quite possible, I had that a few days ago. 73-75% is tricky and above that? Nope if I have any choice. Sometimes I wonder about the people who unnecessarily force themselves into some too fatty woe their body feels bad on just because they have read it is a must for keto. No, it isn’t.
Carnivore is keto to me, I am simple but if I am wrong, sorry, fortunately I don’t care if it’s about my woe, I try to follow what feels right, it’s not about keto but health and well-being. But I am aware it’s separated for others and actually, for me too. My carnivore-ish is keto but I call my woe “keto” when it’s farther from carnivore and “carnivore-ish” when it’s super close or actually is carnivore.
I couldn’t do it more concise, sorry.
TL;DR: Keto seems a good name for me as ketosis is the point and people manage to use the same name for more or less different things anyway, it’s inevitable. I don’t think I know a single sustainable woe where the name means similar things for everyone… But many people judge like it would mean the same thing: what they themselves think about it.
