I have been decreasing my carb intake for about 3 weeks and I stopped eating any carbs at all (just beef and salt) one week ago. On that day one week ago I measured my ketones level and I was at 0.7 mmol. I also measured today one week later of just eating the beef and zero carbs after I woke up in the morning and I now got a value of just 0.1 mmol ketones in my blood? How is this possible when I have had zero carbs since the last measurement? Should my ketones not naturally just rise or stay at the same? At this level I am not even in ketosis? And from what I understand I need ketones as that is my "fuel" now when having zero carbs?
I wonder if one culprit could be the amount of protein I get from just the beef? I eat 1.4kg daily and that is 370g protein (215g fat). I need to eat this amount of meat to keep my weight.

Thank you for the answer. I actually measure my ketones in the blood. I have tried first time in the morning and also after meal but still had the same of 0.1 mmol now.

Thank you, is the LDL going up a concern for you?

I have long been curious about trying out the carnivore diet. I am quite strict with what I eat and I lift weights regularly with the aim of building more muscle while still staying within a healthy bodyfat %. (usually around 14-16%)
Currently I eat about 2800 kcal a day to maintain my weight.
I tried to put into my food calculator though how much meat (beef) I needed to eat per day to reach that goal of 2800 kcal and that is almost exactly 2.5kg of meat (2500 grams)
That is a whole lot of meat and according to the calculator 520 grams of protein (0 carbs and 87grams of fat).
Any thoughts on this and how much meat do you guys eat a day?
