Reduced mental clarity can have various causes, ranging in severity from 'very minor' to 'very serious'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose reduced mental clarity, we could:
|West Nile Virus||1%||Ruled out|
|Excess Water Consumption||0%||Ruled out|
|Kali Phos Need||0%||Ruled out|
|Vitamin B12 Need||0%||Ruled out|
How 'clear' is your mind / thinking? A 'clear' mind comes quickly and accurately to conclusions; a 'foggy' mind has trouble doing calculations or making decisions that should normally be simple.
Possible responses:→ My mind is always/almost always 'foggy'
→ My mind is often 'foggy'
→ Average / don't know
→ My mind is usually 'clear'
→ My mind is always/almost always 'clear'
Experts have voiced a longstanding concern that ketosis might fog up people's thinking, but it took until 1995 to be formally tested. As reported in the International Journal of Obesity article "Cognitive Effects of Ketogenic Weight-Reducing Diets," researchers randomized people to either a ketogenic or a nonketogenic weight loss diet. Although both groups lost the same amount of weight, those on the ketogenic diet suffered a significant drop in cognitive performance. After one week in ketosis, higher order mental processing and mental flexibility significantly worsened into what the researcher called a "modest neuropsychological impairment."
