Your brain adapts to using ketones as well, doesn't it? Otherwise if you were on a low carb diet your brain would just stop functioning, which it doesn't?

Yeh I was right, your brain uses ketones for energy and after a few weeks can derive ~75% of its energy from ketones.

Also, if ketones are poisonous how are epileptic children kept in a state of deep ketosis for 3 years or more without problems?

Some studies for you to look at: http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=pubmed&cmd=Display&dopt=pubmed_pubmed&from_uid=14769489

What you are talking about only happens over excessively long periods of starvation like over a month.

Until then, the brain utilises glucose as it's energy source

Or as soon as glycogen reserves have been depleted? Any glucose made by gluconeogenisis from proteins is 'spared' from being metabolised by the brain.

EDIT: I shoud have paid more attention to Rubery's lectures...

Exactly, and you can deplete glycogen stores in a few hours if you're keen :smile:

Also, when ketones reach a certain level in healthy individuals insulin is secreted to keep the levels in check.

Actually Guys Insulin Isn't An Enzyme!

Its a hormone, who said it was an enzyme?

I was going to ask that a few minutes ago, and reread the thread and found this...

Yes - hence what I said in my post:

The brain gradually switches over to ketone metabolism as an alternative to glucose.


The subsequent post (about not quite 100% fat metabolism) was referring to the fed state, as you were :p:

They're kept in a state of controlled ketosis. Diabetic ketoacidosis can be fatal because ketone production is uncontrolled and causes the blood pH to drop below 7. It seems they (like urea and other small ions) are the sort of thing that in low doses can be beneficial, but in higher concentrations can be toxic.

I think you produce ketones when your bodies goes into starvation mode.

ok well cheers for the replies, there was a trace of protein present as well don't know that makes much difference but could it be anything to do with being up at night and sleeping during the day? Maybe my whole metabolism is messed up or something I dunno. My mum said it is when I suggested it but shes probably just saying it so I'l wash up and hoover every morning.

Yes I wanted to know if anyone else has the same thing/problem, everytime I bring up the topic she starts yelling saying im a hypochondriac but theres something that shouldnt be there :confused: Ive looked it up on the net and ketones in urine is apparantly a dangerous sign yet shes telling me to stop worrying and that I just need to eat properly (I haven't changed my diet at all) and sleep at the proper time. I'l go to the docs if they are still there in a few days.

Also Ive done a blood suger test twice in the last week and it was in the normal range first time 5.1 and second one was 4.3. So according to that im not diabetic unless diabetics sometimes have normal results though? I don't know much about this stuff.

Yes, ketones in urine can be a dangerous sign, but you only had trace amounts, right? That doesn't mean anything at all, and given that your glucose is entirely normal I really doubt you're diabetic. There might be something else going on that we don't know about, but you can't tell it from those rather inconclusive urine test results.

You can still have normal blood sugar levels, but your body could be excreting glucose instead of storing it therefore this would not actually affect the level in your blood.

But HOW is it excreting it? It's not via her urine, because there were only trace levels in there. I'm not quite sure what you're trying to suggest, but from over here it makes little sense physiologically.

She could be sweating glucose:eek:

I doubt it! But she could only be excreting small amounts anyway (in urine) - I doubt she's got full-blown diabetes

I did a urine test today cause ive been feeling anxious, weak these last few days, well my mum told me to do one and show her the result after to proove theres nothing wrong cause shes a nurse and says im an hypochondriac. Anyway she said there was a trace of ketones and glucose present and otherwise im normal. She keeps saying dont mither her but im now concerned cause on the internet it says stuff like contact medical attention immediately if ketones are found and that its a toxin that can harm the body etc.
Does anyone know anything about this


are you on affordable by any chance, im sure i recognise this post from somewhere?
