General guidelines, rules of thumb, and winging it are fine if itâs working for you. But if youâre not getting the results you want, more precision is required. Ketosis is not a feeling, itâs physiological state. And itâs measurable. The adaptation clock doesnât start ticking until youâre in ketosis, and you donât know if, when, or how much time youâve spent there because you donât measure.
Buy a blood glucose meter. The machine is cheap and the strips are cheap. Take readings everyday until you figure out how you body responds to the foods you eat. If you can afford it, buy a blood ketone meter. It will enable you to more easily determine energy utilization within your body.
Lastly, if youâve felt crappy for the past 4 months as a result diet, more investigation is warranted. A relatively LC diet even with donut consumption, should not cause you to feel more crappy than usual on your SAD. The oft mentioned keto flu occurs because of inadequate energy availability as a result of one energy source (glucose) being withdrawn before another energy source (fatty acids) can be fully utilized. If you have been over consuming carbs, keto flu canât occur. I donât think how you feel can be attributed to that.
