Last week I posted about eating a large amount of prime rib at an all you can eat buffet and that the next day I checked my blood glucose and ketones and found I was not in ketosis. However one issue I didn’t consider was the dawn effect. So I decided to do it again yesterday I checked my numbers before eating and I was at 98/1.5 what would appear to be good numbers. After eating 45 oz of prime rib I checked my numbers 30 minutes after and it was 100/.8 only slight ketosis then again after 3 hours and the numbers were 114/.5 out of ketosis. So now I have to try to deduce rather or not glucgenesis is real and too much protien turns into glucos and can kick you out of ketosis or if the crust of the prime rib had carbs and if I truly ate enough crust to kick me out of ketosis. I will say that the cust appeared and tasted mostly like a regular salt and spices crust but I know carbs are sneaky! Thoughts?
Protien kicked me out of ketosis?
Is ketosis important for you? I just want to feel right so I don’t even care about the animal sugars I eat as my body seem to be fine with them. Never could track ketones but I don’t think it matters to me.
But you won’t eat this much protein often, right? Why would it be a problem occasionally? (Maybe it is for you, I can’t possibly know, I just saw too many people chasing measured ketones, not the important things…)
And I have read zillion times that gluconeogenesis is demand driven so we shouldn’t worry about it… Still, I have read many times that carnivore isn’t necessarily keto. I don’t get it myself but I don’t care about it anyway, I just aim to be healthy, feeling well and my body definitely has some problems with plants - or theoretically adequate protein. I need high protein and it feels right so be it. But I know some people need high ketones for some reason, usually therapeutic…
Wow. That’s a respectable amount! Beyond me and I can eat 
Spices are very carby. The amount is usually not much but for that much, who knows? Our personal tolerance is different anyway…
@Shinita Respectable, common sense answer! Thank you. I do want to value the data but I also agree my subjective experience needs to be a part if the equation. I can say that both days of eating that much didn’t leave me feeling great the rest of the day or the morning after. So there’s that.
Yes, it’s real, that’s never once been disputed, it’s literally biological fact. What (used) to be disputed is whether it’s supply or demand driven, it’s demand. You ate almost 3lbs of prime rib, or COURSE your body had to start doing something about a completely excessive amount of beef going in, so it started burning it as a fuel, which is what you saw. That’s literally what the meat sweats are.
The false fear of GNG was based on people eating normal and optimal amounts of protein having issues because of it, but that’s not what you did, you went way off the reservation, in any normal situation GNG is nothing to worry about, that’s aside from the fact that coming out of ketosis because your body is in freakout mode from excess levels of protein is very different than it doing that from carbs, with carbs you’d have liver stores of glycogen to burn off after the fact, when the GNG stops, you go right back. Keto doesn’t mean unlimited fat and protein anymore than somebody eating SAD gets away with unlimited carbs. Anything can be overdone.
Thank you for your reply! Thank you for clarification around the disputed aspects in GNG. I really did go off reservation! Lol I agree that keto life style can’t be an excuse for me to gorge out of control.
As somebody that’s fought binge eating for longer than I can remember, no judgement here, especially when it comes to meat!
It didn’t kick you out if you still registered 0.5 but that much beef in one sitting lowered how deep into ketosis you were. Out of curiosity, why did you eat that much? For science? 
@MeganNZ I used to eat a lot for sports, lifting then for comfort. I liked to pride myself on how much I could eat. I think I still have this mindset sometimes. I am truly addicted to food. I was successful on keto a few years ago and lost a lot of weight but what drew me was the lie that I could eat as much as I wanted and at first it seemed true. Now I’m back on and I know I really can’t get away with that kind of thing anymore.
I always eat too much on keto so I always stay fat, of course you can eat too much. Eating as much as you want works in some cases and not in others. It doesn’t work for you if you eat an excessive amount because you can and like to do it (by the way, doing it regularly with really high protein isn’t healthy, we have our upper limit, most of us merely never reach it. I probably do but only occasionally and one day is no problem for my body. I never ever had meat sweats but the most meat I ever ate was only 1kg on a day and I didn’t repeat it the next day. I am a short woman, not even particularly muscular so it probably was quite much for me. it wasn’t my only protein source on that day…). It doesn’t work if you have a smallish energy need and can’t eat that little (or below if fat-loss is the goal). Or you can but your taste and protein need keeps you from that (I am like that. I need my high protein but then I virtually inevitably overeat fat as I can’t eat lean… I try to solve this and I have methods but they are tricky to realize. and it’s just the base, I always can eat a lot more out of joy, compulsion or necessity. I mean when I have fattier options, it’s a necessity to eat those. I do my best to avoid this case. but I digress, sorry).
Many people start to eat little enough on keto so they have success even regarding fat-loss. Some say they eat much but it still works for them for some reason, maybe they are the ones where keto raises metabolism, I never had that, sadly. Only overeating raises my metabolism as far as I can tell but my body isn’t weird to do that to get a deficit… So I typically maintain there too.
Some of us need fine tuning. Or some huge change (I dropped almost all plants, it wasn’t enough but a good step. more like a big jump as I started to eat meat too). For fat-loss, for feeling better…
Out of curiosity, how much meat/protein you eat a day when you don’t try to set some record or prove how much you can eat? Occasional days are one thing, I don’t think they have a big impact on your keto, I always focused on my average/normal day, that should be right. We may need exceptional days for fun, for experiments or because we need more meat/food at some point, that’s okay, I totally get it. And while I am not happy when I really overeat, it is interesting to collect some monster numbers (Like my over 250g for both fat and protein on a lovely carnivore day. It’s very easy to do, I didn’t even try, it just happened. I probably wanted to eat little as always but I am not very good at that.) I just don’t want to do that often. Once per every few year sounds good… I could get away with more but such days are wasteful, unnecessary. I try to keep myself in a more normal, controlled state as I am prone to go wild, no need to encourage it… But sometimes one needs a wild day. At least I do. Still, a better food choice may be an option. I eat as much as I want - but not using my most triggering items…
Many ketoers need to learn what items to avoid - or use carefully but at least very rarely. I have dangerous, triggering items even among the meats, I don’t even need carbs for that…
@Shinita great reply, thank you. To answer your question I have been eating anywhere from 120-200 g of protien on average 150. I am current 5’8" 319 lbs male.
That sounds a fine amount, I eat about the same amount as it’s the minimum I can do.
No need to worry at all then, I say.
