OK well this is in my opinion only.
I have followed a ketogenic diet (less than 20g of carbs per day) for the last 4 months.
Before that I followed LCHF although was probably in ketosis most of the time anyway.
I also practise fasting both intermittent and extended.
I don't have breakfast just 2 mugs of tea sometimes have lunch (or maybe just a coffee with cream and sometimes coconut oil) usually have dinner.
I don't consume an excess amount of fat but also don't fear it so will eat fat on meat cook in butter or ghee and add butter to meat if not very fatty.
I find that I do not get "hungry" very much so this way of eating ( i don't call it a "diet") suits me.
Meals are usually composed of meat and veg (above ground only) or salad and lunches eggs and bacon , or crab and avocado etc.
Sounds like you are eating a lot in your 7 days of keto also you seem under the impression that you go into ketosis overnight. This is not the case. Overnight you are effectively fasting something which I prolong by not eating breakfast.
Until you have exhausted your glucose from carbs then you cannot be in ketosis. This is why it takes time to get into ketosis and why eating carbs will push you out. The level of carbs is individual but the vast majority of people should be in ketosis with less than 20g of carbs per day which is why that figure is bandied about.
The 130g of carbs per day for your brain to work is manifestly untrue or I would be dead. Your body will make glucose for the brain if required by using protein via gluconeogenesis.
I am currently experimenting with a "zero cab" month during February where I eat only animal products (and tea and coffee) no plants at all. Cheese, cream and butter along with meat and fish.
That's me...
however I have been diagnosed with Type 2 although currently unmedicated and no symptoms. Stats are in my signature.
Thanks for the reply. If your way of eating works for you, then you'll hear no complaints from me.
The issue with the keto thing I think stems from how it's presented. It's not the low carb aspect per se that I have an issue with, in fact I tend to agree with the opinion that carbs are not the ideal food for us - and that's before considering how food these days is manufactured cooked and served up to us. We do not live naturally much anymore, if at all. This is obvious from the current obesity crisis. I've had weight problems for years, ever since the late 90's when i found myself (if memory serves) eating a large plate of white pasta with tuna and cheese daily. Now i'm needing to go from 14st to 11. Quite a drop and something I've never found easy, even though i've never hugely obsessed about it.
So the keto thing is twofold for me:
1. The cognitive dissonance surrounding fat. Some people say it's healthy; they seem scholarly and qualified, but are in diametric opposition to the current paradigm. THis isn't as simple a debate as which colour shoes shall i wear today either. It could be, and for some it is, life or death. I have no problem with eating fat - just with whether I believe the evidence is clear.
2. Nutritional ketosis. You say that one doesn't enter ketosis over night, but that's a claim made in this discussion already. I suspect there is unintentional equivocation over that word. I think the over night ketosis is just the word used to describe the simple fasting state we enter at times like sleep. What the diet people are talking about seems to be Nutritional Ketosis, which seems to be a little bit different. A state that requires a specific diet that is only reached after a possibly significant period and potentially some physical hardship (YMMV).
THis is an issue because it sounds artifical and rather 'health guru'-esque. Having to put yourself into what seems like an unnatural metabolic state sounds extreme! Like a david blaine stunt. Then having to maintain it by ferociously micromanaging your diet and counting carbs? Is that reasonable or normal? Yet people speak euphorically about it.
It's not the low carb element that's the issue: if this was just 'eat less carbs and be healthy' that would be fine. It's all this extra mysterious stuff that leaves so many questions in the mind, which is what i've had. Of course searching the internet for answers is like hopscotch across a minefield; everyone's got an opinion on this and everyone seems to know the truth, no matter if their answers conflict with others.
that's not a dig at anyone here, btw. I'm really talking about reddit. Most of the other keto websites i've looked at, including Diet Doctor, hide their content behind paywalls, which is not entirely helpful.
So this whole nutritional ketosis thing is anomalous. Is it natural? It is even really safe for everyone? Why does it make some people ill at the outset? Does everyone who reduces the carb intake, for any reason, invariably enter this state? I presume they must since that's the requirement.
Then there's the question of how you meet your caloric requirements if you do reduce carbs, because of course it isn't just as simple as choosing not to eat X, that's simple enough. If you go down 100g carbs or so, as I have by cutting wheat and rice (which i'm fine with), then that shortfall is going to be felt, even if you reduce your calories in order to lose weight. You surely can't just reduce them massively without balance - or can you?
IIRC (and please correct me anyone if I'm wrong), there's 4cal per gram of carb and protein. So on lets say 30g carb and 80g protein, which seems a reasonable amount (for me at least), that's 440cals. You get 9cals per g of fat, so if you want to add another 1200 on top of that you're looking at 133g fat. I've no idea what my fat intake was previously, but conventional dietary requirements (wrongly or not) advocate half this. THat's still a relavtively low caloric intake, evne for losing weight I think. But again, please correct me if I'm wrong.
So that's what this is all about for me.
It may be that I've eaten a lot over the last 7 days. Breakfast was 2 sausages, 2 slices bacon, 1oz kale, an avocado, dinner was 1 chicken leg portion, fried cauli rice, pepper, broccoli and mushroom, with an oz raw spinach and maybe some cabbage. I find eating stuff like broccoli cabbabe and kale hard going if it's not cooked somehow; like chewing sand. Lunch varied between sliced cheese, lettuce, brazil nuts and hardboiled eggs (i had 2 today, while i was in town), and a smaller portion of cooked chicken (a thigh portion from tesco) and some cabbage/lettuce, and nuts. If that's too much, I've no idea. I was focussing on those darned macros using myfitness pal to track it all.
Sorry for the enormous reply; i hope your condition improves as others seem to have experienced.
