Brown Fat And My Californian Pool
October 31, 2011
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

Because presently we are traveling - San Diego - Washington - Boston, and my brain is scattered, I just give you some words of wisdom by Sebastian Kneipp (1821-1897):
"Big dinners fill coffins."
The French Paradox
May 20, 2011
We arrived in Paris on Sebastian Kneipp’s birthday – on the 17th of May and celebrated with a glass of wine. And a lunch consisting of three courses: Onion soup (minus the cheese and the bread), escargots (snails) in garlic, crème brulée. Not terribly healthy – but delicious.
Writing from Paris, of course, I want to talk about the French Paradox.
French people eat more fat (think triple brie and foie gras!), drink more wine (think a smooth Bordeaux!) and smoke more than their US counterparts (think Gauloises!), yet they die less of cardiovascular disease. American scientists dubbed this puzzle the French Paradox – and they have come up with some tentative explanations:
• The French surely are underreporting their cardiac deaths
• The French have their main meal at midday and take more time for it
• The French prefer wine over beer; wine contains healthy resveratrol
• The French don’t snack
• The French eat less trans-fats (frying)
• The French eat less hydrogenated fats (margarine, processed food)
• Perhaps saturated fats are not as bad as we thought
• The French eat less sugar, less HFCS, less white starches
• The French cigarette tobacco is not as adulterated American tobacco
• The whole study might be wrong
American scientists looked for the fat contents, the carbohydrates, the proteins to come up with an answer, missing the big, simple picture: fresh foods. Fresh food contains life-giving molecules beside the three biggies (fats, carbs, proteins). Those molecules are miniscule in weight, but hugely important in how they support health. We are from Nature, and throughout Evolution, we ate whole foods. Only modern “food” production has done away with Nature’s wisdom.
The three biggies were important when people were starving – if you don’t get fat and the other two, all the best polyphenols and anti-oxidants and other small plant molecules will not keep you alive. But now that we have plenty of food (which is a first in history – but don’t forget it is not yet true for every single person in the world), we need to turn to quality of food. Which needs we need to return to real food – the food Nature intends us to eat. And not to make it too difficult: It is mostly vegetables we need to bring back on our tables.
The French are eating real food; Americans are eating plastics masquerading as food. Don’t get me wrong – junk food is inching its way also into the French society. But overall, the French still go to the open market to buy fresh produce and freshly slaughtered chickens and fish. Except for the last item on the list, all the factors may play a role. But the main thing is the freshness of the food. The quality lies in fresh things, grown things – not concocted in the lab and manufactured in bulk.
And by the way, their cigarettes might be a tad healthier – but please don’t start your French new life with Gauloises! Read More
