Hi,
has anyone experienced changes in sleeping hours or intensity?
I'm trying to isolate the variables, but my feeling is that since I
started low-carbing I need less hours of sleep. I wake up before
the alarm goes off, and have no problems getting up.
I've been doing this for a month, and before it was a nightmare
to get up, I was very sleepy.
Of course, it has been about a month that real summer started
where I live, with more sunlight and heat, but I am really convinced
that the diet did it.Not that I am complaining, quite the contrary.
Have you had a similar experience?

It wouldn't be surprising as Dr McCleary of the Brain Trust Program thinks brains run better on a low carb diet.
I also found the same.
In fact I found his site when I was trying to find an explanation for the fact I appeared (to myself) to be thinking quicker, clearer more incisively since the dietary changes, waking refreshed and not suffering from those brain fog periods when it was impossible to read the medical papers about Vit d that I need to comprehend in order to keep up with the constant stream of new D3 research.

Wow, so this is a great side effect for me.
It's like the side effect flyer from medicine but in reverse :-)
"Attention: diet might cause lack of hunger, improved sleep
and brain function and incredible self-confidence" :-D

Yesterday I had planned to eat some fruit after dinner,
but when I ended I just wasn't hungry.
So I thought, before bed, if I get the munchies, I'll
go and have an apricot. No way, I was still full at that
time. After a steak with butter and cauliflower with cream
that is it. I can't stop being amazed at this. And just dropped
another pound overnight. I am so excited!

Why your big interest in vitamin D, if you don't mind my asking?

I was getting pretty desperate after falling regularly and life in a wheelchair was becoming the only viable option when I found Post Polio Syndrome and Inflammation
In searching for ways to reduce my level of pro inflammatory cytokines I came upon Direct MS org supplements list and thought that as the main disabling symptoms of my condition mirror many of those MS sufferers experience I may try using the same supplement list and see what happens.
So finding it did help I researched further into the benefits of Vitamin D3.
Going from 4000iu/daily to 5000iu/daily improved matters but I live at latitude 52N.
I was exceedingly slow on the uptake though and only recently adopted their Nutritional recommendations for MS If I'd have been a bit smarter I would have lost weight sooner and maybe would not have deteriorated quite so much however we all make mistakes. With current official advice linking weight loss with the need for more exercise it is reasonable people who can't exercise assume they either have to live on starvation rations or get fat.
Now I've sussed how to eat as much as I want and still lose weight without the need for extra exercise it's simple. But losing over 3 stone has improved my mobility. I've not fallen for ages.
Getting about is much easier and thus I am exercising more AS A RESULT of losing weight.
What I can't quite grasp is why no one else (apart from a few stalwarts here) why generally speaking few people have cottoned on to the need for vitamin d3.
Do we really think evolution didn't put D3 in breast milk?
Now we know the level at which breast milk flows replete with D3 and the body has sufficient to meet it's daily needs and set some aside for the winter why is anyone satisfied with lower than ideal levels?
If we know peak physical performance is only achievable when this threshold is reached why is the average UK adult status only a third of that amount?

We would consider the person who ran his car with only a third of the oil needed in the sump, a third of the water needed in the radiator and a third of the tyre pressures recommended a dickhead. Yet D3 regulates our levels of magnesium and calcium as well a 900+ different Vitamin D receptor actions and over 200different gene functions.

Can you not grasp the enormous potential for chronic disease conditions that will result from running your system with only a third of the daily requirement of the essential component for each of those actions.

If you think you feel better now getting your carb levels right I assure you that you will feel a much greater improvement when a vitamin d3 status of 50ng or 125nmol/l has been attained and maintained for over a year.

yep, sleep is better wile I low carb. I wake earlyer refreshed and because my blood sugar is under control, 80 to 130 usually highest about an hour after eating 147 I am no longer falling asleep at work because my bloodsugar droped way low.
