Throughout my journey through my battle to get a definitive diagnosis and then finding out why my body does what it does, the question of how much glucose and where we get it from to sustain good brain function, has been an issue.
Every doctor, every dsn, every dietician, every dietary advice, even from my specialist endocrinologist said I must have complex carbs to sustain brain function.
It is simply not so!
Maybe I am a bit weird, but I have found that I actually don't need any form of sugar to feed my brain through dietary intake. In fact, I feel much better not eating or fasting and my brain actually works better than after a meal, regardless of how low carb it is (very!)
My job, is very demanding on my brain, I have to retain lists of items, admittedly with paper lists, but I have a good working noggin retaining information about certain preferences for individuals, and collective equipment needed.
I can only think of describing it as moving house once or twice a week.
So I need a clear mind and a lot of energy to cope with a very demanding job.
Being in or near ketosis, eating only protein, salad vegetables, some fruit, knowing what my body is capable of handling, helps my health, my longevity, my bank account.
In my experience, your brain only needs very little glucose from any source.
Final question for those who are interested.
So many people who do not diabetes or metabolic conditions have symptoms of a sugar crash in the afternoon.
Mostly, falling asleep, sluggish, brain fog!
Why?
