What do Da Vinci, Napolean, Thomas Jefferson, Buckminster Fuller, Nikola Tesla, Thomas Edison, Winston Churchill, Margret Thatcher plus many other noted great minds have in common? For as long as I can remember I have been waking up utterly exhausted usually from nightmares and it takes me all day to get my energy back.
The nightmares in the early morning hours make sense in that cortisol is a a stress hormone, and leads to nervous system activation. I don’t want you to get the impression that cortisol is evil, it is naturally very good for you if your survival is threatened and your in danger and need to move quickly. There is also good ancestral evidence that humans for most of history only slept 4 consecutive hours at a time, breaking their sleep up into chunks.
People were becoming increasingly time-conscious and sensitive to efficiency, certainly before the 19th Century,” says Roger Ekirch. Strong evidence of this shifting attitude is contained in a medical journal from 1829 which urged parents to force their children out of a pattern of first and second sleep.
The idea that we must sleep in a consolidated block could be damaging, he says, if it makes people who wake up at night anxious, as this anxiety can itself prohibit sleeps and is likely to seep into waking life too. Russell Foster, a professor of circadian [body clock] neuroscience at Oxford, shares this point of view.
Over 30% of the medical problems that doctors are faced with stem directly or indirectly from sleep. The theory is if you sleep only 4 hours, get up and sleep again 12-ish hours later, you can get another deep cycle in.
When i first started taking resistant starch it seemed to me that it was coaxing my body more towards this polyphasic style of sleeping. Low DHEA and testosterone levels are also a consequence of high cortisol demands as the precursors are depleted due to the primary survival demand of cortisol which takes hormonal priority in terms of production and utilization.
While a double COMT variation has the downside of poorer stress management it does have the upside of there being naturally higher levels of dopamine in the brain which is thought to increase intelligence. Now I know many people are probably quite adverse to changing the way they have been sleeping their entire life.
Fasting blood glucose is a measure of the quantity of glucose present in an individual’s blood stream after abstaining from eating for at least eight hours.1 This test is used to screen for diabetes.
The chart below provides fasting blood sugar numbers and descriptions as provided by the American Diabetes Association.

Impact of a1c screening criterion on the diagnosis of pre, Diabetes, a condition associated with high morbidity and mortality, has reached epidemic status among americans . Normal-weight obesity, also known as “skinny fat,” is a growing problem in the United States.

A major problem for these folks is that they often are misclassified as healthy when they actually could be at high risk for chronic disease. A recent study showed that percent body fat was inversely related to cardiorespiratory fitness (CRF)—a strong predictor of cardiovascular disease and premature death (1).  Subjects that had larger amounts of body fat were found to be less fit, independent of body weight or stature. Numerous studies show similar trends between body fat and risk of chronic disease and mortality.
In a study that reviewed the relationship between cancer mortality and various adiposity (obesity) measures as well as fitness (quantified as the duration of maximal treadmill exercise test), researchers found that unfit, underweight subjects were at a higher risk of mortality than the obese, fit subjects (2).
In addition to supporting weight loss and preventing weight gain, increasing your muscle mass contributes to overall health and prevention of disease.

The views expressed in the contents above are those of our users and do not necessarily reflect the views of MailOnline. Polyphasic sleeping is the practice of breaking up sleep into multiple time periods (phases) in order to reduce the total number of hours sleep needed.
While many things in the body ebb and flow, that is more like a massive spike similar to a huge insulin spike for someone who has poor insulin control, rather than a nice fluctuation around a homeostatic line. It is only with the recent age of industrialization where maximal daylight work hours were trying to get squeezed out of human laborers.
But sleep has been ignored in medical training and there are very few centres where sleep is studied,” he says.
The deepest most rejuvenating sleep occurs at stage 4 and two cycles complete after roughly the first 4 hours of sleep. Meaning in a 24hr time period you could perhaps get more deep delta sleep in if you split it up. The natural outcome would be that I would be eating every 4 hours instead of starving myself for 8 and inducing a massive cortisol spike. I mean who purposely wants to impair their immune system, slow healing and rejuvenation in the body, enhance catabolism right when you want to be doing the opposite? Based on my personal nutrigenomic analysis I have a double mutation on the COMT gene.  Practically this means I have a 3-4 fold reduced clearance of the neurotransmitters dopamine, epinepherine (adrenaline), and norepinephrine from neural synapses.
Due to the my COMT variation the stress effects will be more acute as well as last longer due to slower metabolism of said catecholamines from mys system. I now, force myself to wake up after about 4-5 hours of sleeping and eat some carbs to boost insulin a bit to dampen cortisol. No need to be envious anymore, because science says body composition—the ratio of fat to lean body mass—is a greater determinant of health than just plain body weight.
These terms describe a person’s body composition that is high in fatty tissue in comparison to lean tissue, while still within normal limits of the body mass index (BMI). While much focus has been on how increased body weight can lead to a greater risk of disease, little emphasis has been on the health risks associated with being underweight and unfit.
These results suggest that, in addition to weight management, physical activity should be emphasized as a critical part of a healthy lifestyle and disease prevention.

This coincided with the nationwide introduction of an education and food labelling programme aimed at improving diet and health.
Eating food and carbs specifically generates insulin which counteracts cortisol and helps bring that down cortisol throughout the day.
Perhaps westerners have got it all wrong and some insulin promoting carbs may be better, a potato or some rice perhaps. The next 4 hours are not nearly as rejuvenating as the stages are not as deep, which lead to fragmented sleep naturally.
Sleep is supposed to be rejuvenating! The thing is if you do it too much at once, it has the opposite effect. What this means is stress hormones can very easily establish a negative cycle, where stress begets more stress and then your hormones are all out of whack.
This can have a negative feedback cycle effect where stress begets more stress quickly leading to adrenal fatigue. If I’m still tired I will go back to bed and nap, but at least it will be more rejuvenating this way.
Those who are considered to be “skinny fat” do not appear to be overweight; however, they have a high percent body fat, especially visceral fat—the fat that surrounds vital organs.
In the same manner that muscular athletes can still have optimal body composition while technically being in the overweight BMI category, people who appear to be thin can actually have high levels of body fat.

Around five per cent had taken it up seriously, leading the DietDoctor website to hail a "Swedish low carb revolution".
The Vasterbotten Intervention Programme (VIP) continues to this day.After 2004, there was an unexpected change.
And remember you can still get all the sleep you need, just tweak it so your cortisol doesn’t spike. Think of sumo wrestlers who can weigh upwards of 300 pounds—it is possible that they are more fit and healthy than the thin spectators who have a higher fat-to-muscle ratio. Bachman emphasized a balanced diet, physical activity, and stress management as healthy lifestyle practices.
Initially beneficial and thereafter deleterious changes in blood cholesterol paralleled these trends in food selection, whereas a claimed weight reduction by high-fat diets was not seen in the most recent years.'In contrast, BMI increased continuously over the 25-year period.
I usually have woken up muscles tight and stiff, adrenals depleted, emotionally exhausted, energy depleted and no appetite to boot and then not eating which by prolonging the stress response. These changes in risk factors may have important effects on primary and secondary prevention of CVD (cardiovascular disease).'But Atkins Nutritional has dismissed the study - arguing the research was based on diets that were higher in carbohydrates than allowed on the Atkins diet.
Colette Heimowitz, vice president of nutrition and education for Atkins Nutritionals Inc, said: 'The study referenced completely ignores a large body of literature that points to health promoting effects of low carbohydrate diets.
