insulin resistance studies. June 5, 2018

"Our preliminary findings show that a single night of light exposure during sleep acutely impacts measures of insulin resistance," said lead author Ivy Cheung Mason, PhD, who was a postdoctoral fellow at Northwestern University Feinberg School of Medicine when this study was conducted. "Light exposure overnight during sleep has been shown to disrupt sleep, but these data indicate that it may also have the potential to influence metabolism."

This is studies and in studies there is no measure the most important part of study, Insulin Resistance. There is even no definition, what is it, Insulin Resistance. Take a look at the study, and what they pretend that Insulin Resistance is? 

Oral glucose tolerance tests were performed on both mornings following sleep in the dark or 100 lux of light.

Sorry, OGTT is not test to measure Insulin resistance. It is actually measure nothing, truth to say.  Test measure level of sugar at first fasting, and then with glucose loading. Test run two hours. during which level of sugar in blood measured. It is pretend to be test to diagnose diabetes. At the same time when sugar is higher then 200 mg/dl OGTT is not necessary, so it never run in type 2 diabetic. Type 2 diabetics are those types of diabetics who has Insulin resistance, according to Med. Pro.

  Homeostatic model assessment of insulin resistance change values were significantly higher (p<0.05) in the morning following sleep in the light (DL group) compared to sleep in the dark (DD group). This effect was primarily due to increased insulin levels for DL compared to DD group.    

At first, to say "higher" is to say nothing. Show difference if it is. Because of small difference will be all the time at any time, and this difference does not support theory. 
Now what about   "Homeostatic model assessment of insulin resistance"? What is it? There is not so many people who know what is it. It is better to open this measurement in discussion. Yes, there is nothing to open. This Insulin Resistance never measured. It is Math formula how to count Insulin Resistance.

On first look all those tables seems complicated and very difficult to understand. At the same time any table and any picture can be presented by two measurements. According to article, there was only one measurement, OGTT, level of sugar in blood.  So, regardless how complicated table and pictures are, they are all fake. No one picture or table show Insulin Resistance. In studies only glucose was tested. In tables Tests for Insulin used together with level of sugar. But level of insulin never measured. So, what authors talking about?

This is what I use to say every time. Do not donate money to researches.  They study nothing, and never would be able to find any cure for any medical problems. About diabetes and cure for diabetes, say me, why they need to find cure? They do not need it. If there is no diabetics type 2, what all those
