The experiment is still on: How long into the winter will I succeed to keep up my daily twenty-one laps in the pool?
So far, so good. The water is much colder now, but the days have been sunny and friendly – the fog lifted while we were at the East Coast.
Truthfully, lately it has been harder to face the pool: I am still battling a minor cold, and every day I have to decide if it is prudent to swim with the cold, or if I should just snuggle up in a warm blanket. But the exhilarating feeling after my daily swim – I seem to be addicted to it. I look full of vigor. My posture definitely is straighter. I am building up muscles where I never had any – on my back and my arms. Plus, the tiny belly I had is getting smoother (not smaller).
On the negative side is my skin. No outright rash or itching yet, but I have the suspicion that my skin looks a bit older, notwithstanding the coconut oil I slab all over me after each bath.
For a few days, I had been getting extremely cold after each swim, and couldn’t get warm at all. If you ever read my water book, you know that staying cold after water exposure is not a good idea. But with my inborn stubbornness (which might just get worse with age …) and medical curiosity, I kept doing what I should not have done: go swimming. And got colder and colder. In spite of the knee bends, blankets and hot tea with fresh ginger. Two nights in a row, I didn’t get warm all night – certainly not a healthy state!
Until yesterday. Shortly after I went swimming, had taken my short cold shower to get rid of the chlorine, had done my exercise, had rolled up in my blanket and imbibed the tea, I got really warm. Even my hands felt tingling with warmth. This lasted all night, and is still going on. I suddenly had the feeling that, for the first time in my life, that I was getting on the warm side in life. Like, where my husband always is.
Looking around for an explanation, I stumbled onto brown fat. Brown fat gets activated by cold. Brown fat is supposed to be healthier than yellow fat that just stores superfluous calories. Babies have more brown fat because it protects them from hypothermia – a constant threat for newborns.
Brown fat is not so much fat but is related to muscles. Brown fat is brown from the mitochondria and their iron contents; mitochondria are tiny energy factories. Brown fat has also more blood vessels for better oxygenation and is metabolically more active than yellow fat – it actually burns calories instead just storing them.
So, by swimming in the cool pool, I must have tapped into my brown fat – I can’t come up with any other explanation. And did you know? Brown fat is implemented in weight loss. Yes! Brown fat can make you lose weight – IF you have enough brown fat.
Sebastian Kneipp, the father of the Kaltwasserkur (Cold Water Cure) is famous for jumping into the wintry Danube River to cure his tuberculosis. Later, he modified his approach because he observed that some weakened patients were not able to withstand the bitter cold he himself had applied to his body. One could say he watered down his original approach … I had always repeated what I had been taught: that too much cold might be hazardous to your health. Which still might be true for frail people.
But I might be onto something here … I will let you know how this will work out.
P.S. After today's laps, I have very warm hands. Read More

How to Measure Diabetes
July 21, 2010
In ancient times, diabetes was diagnosed by licking the urine of the patient. If it tasted sweet, a diagnosis of diabetes mellitus (“honeysweet flow”) was made. As a physician, I am glad we have advanced to better tests...
There are basically four different tests to diagnose diabetes (I am talking here mostly of type II):
• Spot blood sugar. Since sugars rise and fall depending what and when you ate, this is a very unreliable test.
• Fasting blood sugar. Does only take a bit of blood, is cheap and fast – but still can vary with what one ate the day before. However, if your fasting numbers are up consistently, you should pay attention!
• Oral Glucose Tolerance Test: a complicated procedure where one drinks an awfully sweet fluid before blood will be drawn in half-hour intervals to ascertain how fast the sugar load is cleared out. It’s complicated, and very time-consuming for the patient. I object of giving a patient a drink 75 to 100 gm of unpalatably sweet glucose solution – which can’t be healthy if there is a disease caused by sugar. My suspicion is that this test is still be used because doctors can bill the most for this.
• Glycosylated hemoglobin, also called A1c: An easy blood test that gives a rough average of your sugars through the last month. I like this one the best because the usual ups and downs of sugar are not interfering with the test, but going into the overall measuring. With frequent episodes of hypoglycemia (too low blood sugars), the test might come back falsely low or normal. In iron-deficiency, A1c are higher than they really are, suggesting diabetes where there might be none. Every time one eats sugar, it “glycosylates” (adding a sugar to the molecule) a protein on the surface of an erythrocytes (red blood cells), and the chemical process is never reversed as long as the blood cell lives. Red blood cells live about three months; blood we draw is always a mixture of very young cells, newly released into the bloodstream from the bone marrow, and older cells, soon to be discarded. Measuring blood glycosylation therefore represents a fair mirroring of recent sugar intake and over time, those numbers can be compared: A lower A1c means you have done something right lately.
In conventional medicine, A1c is called normal if it is below 6.0. A1c is measured in percent of how much of the blood is “sugared”. Starting at 6.1, you have diabetes. That in it itself is rather absurd: A little step upward from 5.9 to 6.0 does not give you diabetes – you had it coming all along. In Natural Medicine, we think that between 5.0 and 6.0, one has “latent” (developing) diabetes. Why that number of 6.0? Because if one would chose 5.0 as the cut-off point, most Americans would have to be diagnosed with the disease.
The Oral Glucose Tolerance Test is more sensitive to detect cases of diabetes – but only if the cut-off point for diabetes is set at 6.0 A1c.
Arbitrarily putting the number to 6.0 does not make a person healthier. In fact, at the date of diabetes diagnosis, I good proportion of patients have already end-organ failure, namely eye problems, kidney failure, neuropathy – to name a few.
Just looking around tells us that many people are overweight and have some of the telltale signs of diabetes: belly fat, scant hairs on arms and legs, rosy cheeks. One sign alone does not make the diagnosis – but several together gives me an idea. But one can be very overweight and never develop diabetes, because in order to get the disease, you have to have the genes AND an unfortunate lifestyle.
Don’t think that genes are an excuse. Because diabetes type II does not strike, if one lives frugally. For instance, after World War II in Europe, basically nobody had it (but people died in droves of tuberculosis then…). Ten years later, with ballooning economies and waistlines, diabetes was back.
But you don’t have to starve yourself, to heal diabetes. You need a mixture of moderate movement (walking, swimming, biking – or dancing; whatever you like) and a diet without sugars, white starches and bad fats.
In diabetes drug studies, diabetes often is called “controlled” if the blood sugar stays within the limits if 7.0 to 10.0 A1c. We can be sure that at those numbers the damage done by high sugars is continuing in the body. I personally favor an approach that does not “manage” the patient’s diabetes, but gets rid of it. And in many cases it can be done, with exercise, better nutrition – and determination on the patient’s side. Read More
