I discovered this morning the problem of gluconeogenesis! Gluconeogenesis means that the body creates glucose out of non-carbohydrate sources, notably protein. I accidentally ate too much protein yesterday, which in turn lowered my blood ketones drastically this morning. Normally my blood ketones are around 3.2 mmol/l, but this morning it was only 0.8! Still in ketosis, but just barely!
I realized what it was that caused it. It was whey! When I make clotted cream, the clotted part is the fat (basically butter), and there is liquid part, which I thought was still cream. But the liquid isn't cream, it is whey! Which is protein! And yesterday I had only the liquid part, not the clotted part. So when I thought I was having fat on the side, I was actually having more protein. Live and learn! Have to drain off the whey!
Just a reminder of how important it is to keep protein low. The basic rule is to have only 1 - 1.5g protein per kg of body weight. For me, that means just 66g protein daily! I've been averaging 80g. So I should try and keep my protein intake a bit lower. That means eating more fat!
Here's a link to an excellent article explaining how important it is to maintain a good high intake of fat:
All traditional carnivorous diets, whether eaten by animals or humans, are more fat than protein with a ratio of about eighty percent of calories from fat and twenty percent of calories from protein.

"Why Low-Carb Diets Must Be High-Fat, Not High-Protein" by John Yudkin
The author explains that traditional diets contained 80/20 percent fat/protein. I have just been averaging around 70/30. I will make an effort to eat more fat! What a delicious task!
