Ketosis Levels Slowly Dropping
I started a relatively strict ketogenic diet this past summer and was able to maintain reasonably good levels of ketosis (between 1-3 mmil). I noticed however that by the fall, it was rare that my levels went above 1 mmol, and now, it is rare to get them have .5. I am eating pretty much the exact same diet (5-10% carbs, 12-20% protein, 75-85% fat), yet my ketones just aren't rising. I eat such a clean diet so this is all very confusing. Sometimes I try a carb meal to shift things up, and my ketones rise a bit, but then they go down again. I do IF quite often, eating within an 8 hour window.
I don't understand what's going on. Someone said that maybe my body is just adapted to burning fat, but I really need the higher ketones for my brain. It's only when the levels get above 1 that I feel the actual benefits of ketosis - in terms of clarity, focus, etc.
Would love some help understanding this. Has anyone heard of this before?
