From the NHS website: The symptoms of hypoglycaemia usually begin when your blood glucose level drops below four millimoles (mmol) per litre.
Symptoms can vary from person to person, and it's important to be aware of the early warning signs so you can treat them.
Signs and symptoms of hypoglycaemia can include:
- feeling hungry
- sweating
- dizziness
- tiredness (fatigue)
- blurred vision
- trembling or shakiness
- going pale
- fast pulse or palpitations
- tingling lips
- irritability
- difficulty concentrating
- confusion
- disorderly or irrational behaviour, which may be mistaken for drunkenness
If hypoglycaemia isn't treated promptly and your blood glucose levels drop low enough, you may become drowsy or even lose consciousness.
On some of my earlier rides, that I have written about in earlier blogs, I certainly experienced many of those symptoms when my glucose fell. On those rides I was not fully fat adapted and had low ketone levels. When you are fully fat adapted and ketogenic your blood sugar becomes significantly less relevant.
There was an experiment in the 1950's where they took a person/persons (not sure) who they made fast for a significant time so they were completely fat adapted and ketogenic. Over time they administered insulin to drive their blood sugar lower and lower. They pushed it to incredibly low levels where medically a "normal" non fat adapted person would have shown all the symptoms above, lost consciousness and ultimately died. The fasted ketogenic subject was absolutely fine and said they could function normally. I can't remember the exact scientific details so will post the link to the paper when I can find it. It is referenced in "the art and science of low carb performance" but I can't find my book.
So with the above in mind I set off for a ride, with just some salt and a pint of water. I felt pretty good, especially considering my 3 hour ride yesterday, I pushed much harder in the first 30 minutes. I did get a mild headache after that, so I backed off and maintained a more sustainable pace for a further hour. The headache passed almost as soon as I backed off. Glad I pushed my self out of bed and I felt I have earned the pub lunch today.
Had a great time at the pub with a lovely meal, couldn't even finish my portion! Pork belly is a great filler. Lunch was very filling so just a light night in the evening as really not hungry.
