My experiment is going on. Of course, I have no idea if it is really new brown fat that turns me into an oven every time after my daily cold laps in the pool. For all I know, I could have a not-yet-recognized infection or any other disease that makes me burn up. Only thing I know is that I feel terrific – for the moment.
But for the sake of an interesting exploration, let’s stick with my brown fat hypothesis. This is what I have learned about about brown fat so far:
1. It used to be thought that only babies (protecting them from hypothermia) or bears (keeping a reasonable core temperature during hibernation) have brown fat. It turns out that traces of brown fat are still around in adult people. – A little aside: Other ways to increase body temperature are increasing surrounding temperature, moving about, shivering, and eating certain “warming” foods like cinnamon, ginger, onions, garlic, rutabaga, coriander, cloves – interestingly foods often used in the winter kitchen. But there is no hint that those foods increase brown fat. Or a shred of a proof that a so-called "Brown Fat Diet" will increase that precious tissue in your body.
2. Brown fat can help weight loss by increasing metabolism speed.
3. Brown fat also can decrease elevated insulin-resistance (also called pre-diabetes) and a diabetic situation.
4. Brown fat can be induced to increase by cold exposure – be it by swimming in cold water, immersing in a tub filled with ice water, or dancing in a walk-in food refrigerator (don’t you wish you had one of those at home??).
5. Needless to say, there are already pharmaceutical firms are already working on drugs that might trigger growth of brown fat, without going through the ado of cold exposure. The easy way out, I call it. And definitely not an interesting way, if you ask me.
I like to think about cold-induced brown fat as one of the benefits of moderate stress. We all know that stress is bad for you, don’t we? Not necessarily though. Moderate stress might be what makes the body function in the way Nature intended it. With heated dwellings with forgo the winter cold stress – and get sick for it, lacking brown fat. With air-conditioning in the summer, we miss out on the sweating which give our body a good cleanse of all the toxins – and get sick for it. Occasional hunger stress (fasting!) is another beneficial stress mechanism. Not only do we get healthier on occasional fasting, and live longer with less belly ballast, it also seems we get to be happier with fewer pounds – and less depressed.
One estimate is that there are about three million residential swimming pools in California (I am not even mentioning the pools in Florida and all across southern U.S.A.). If these pools are anything like our pool here in La Jolla, all those turquoise eyes should be gazing at the sky, basically unused. All, of course, using up precious water resources. How about using them? If you are in decent health (ask your physician), you start by doing a single lap across your pool. Tomorrow two, and every day one more until you reach twenty-one laps. The brown fat will appear very fast – and will help you lose weight.
Putting on brown fat, however, might mean walking a fine line: You want to increase your metabolism by cold exposure. But you don’t want to get where most winter swimmers end up: with more fat on their bodies. Fat (of any kind) protects against cold, and makes you better able to withstand long swims in icy water.

Listen To Your Body
October 29, 2011
A stalk of Brussels sprouts survived in my fridge while we were traveling to the East Coast. Last night, I suddenly had the vision that I would like to eat those green little roses – and of all things with raisins!
No clue where it came from. The sixth sense? But I knew I had to get up a bit earlier this morning to actually cook this strange breakfast for myself. Since the nearly twenty years I don’t indulge anymore in the ubiquitous müsli or cereal breakfast, I usually eat dinner left-overs or open a can of beans, throw in a handful of fresh or dried herbs, pepper and salt, and some olive oil – it is a fast meal, but no junk food.
At this point in my life, I take my gut feelings seriously. So I browned two large onions in coconut oil before I added the Brussels sprouts rosettes and a cup full of raisins. I let it simmer with some pepper and salt, until the rosettes were soft and the raisins plump. It was delicious – why had I never thought of adding raisins to this dish? The taste mingled the sharp black pepper and the sweet raisins to a new experience. Usually I serve Brussels sprouts with a good sprinkling of nutmeg.
Why do I take my hunches seriously? Because I figure my body wants to tell me about a slight deficiency. Of course I don’t follow hunches for marshmallows and M&Ms, because they are not natural – although I might turn to dark chocolate if I had a craving for something sweet.
Nearly thirty years ago I followed a hunch to visit a certain museum – five hundred miles away. And through that museum, I met my future (and now) husband … but that is a different story!
Why do I bring up something as unscientific as hunches?
Because daily we are bombarded by health news and scientific breakthroughs and advertisements for new super-foods – it is hard to find our way through this maze of information. I early on decided that I need to see – and feel – the difference in my body, my mood, my soul before I believe any new health hype.
For instance, I always craved more fat in my diet than medical wisdom allowed me to eat. It always seemed that my brain did not function well without enough fat – and I am talking good fats here, mostly olive oil. At that time, I was still timid and told my patients to stick to the official line in conventional medicine, namely to cut out fat. But secretly, I bathed my vegetables in all the fat I desired.
And interestingly, it was me who kept her weight since age twelve, not the people who had been advised differently. I was the one who weighed herself every day on a scale – contrary to what medicine was teaching at that time.
So, now, when you take a new supplement: Do you take it because your doctor/your herbalist/your acupuncturist/your friend/your newspaper told you so? Or because you feel suddenly so much better than before?
Over the years I found out that rarely do I feel better with ANY supplements. Exception are the phytogens (female herbs) by GAIA which I gave been taking for many years now. But I do feel better when I take my daily cold shower (or my daily laps across the pool), when I eat less at dinner and nothing thereafter, when I do moderate exercise throughout the day but feel miserable in the gym. I feel good about myself when I drop a small coin into the hand of a homeless veteran, but feel shabby when I argue to myself that he probably is an alcoholic who deserves his fate (nobody deserves that fate!!).
Over the years I found out that vitamins and homeopathy don’t do anything for me, but freshly cooked meals do. That leaving out dairy cured my asthma, and improved my osteoarthritis vastly. That I need about double as much sleep as my husband, and that I definitely need my small thyroid pill after half of my thyroid was taken out years ago. Without that tiny pill I turn into a nagging bitch (as my husband found out!).
Mind you, I don’t give in to silly cravings like drinking a ton of booze. But the occasional glass of wine seems to be fine. And when I was pregnant, I took very seriously my sudden hankering after lobster, and made my husband drive to a seafood restaurant late at night!
When one turns vegan, most people feel wonderful, initially. Because it is a cleansing diet, after the overload on meats, delis and dairy products of the Western diet. But do you still feel wonderful after a few years on this diet? Or do you believe the vegan ideology more than what your body tells you? Do you feel great after an all-you-can-eat buffet, or do you feel like a stuffed turkey? Do you feel great after a diet coke, or do you have the lingering suspicion you might be addicted to the aspartame and caffeine? Do you feel good after a triathlon, or do all your joints scream?
The big problem of course is that our brain can make us believe what we want to believe, deceivingly. It takes years of practicing your hunch skills before you can trust those wild notions coming out of nowhere. After all, there is something like the placebo effect, which may make you feel good erroneously – at least for a time.
But nobody else can answer the question “How are you?” – except you. Because every body is different, and only you can feel how you are. As my friend Roanne Weisman puts it: Own Your Health!
And, hey, I feel perfect today after Brussels sprouts with raisins! Read More
Vegetarian? Vegan? Omnivore?
August 13, 2010
We had this before: I am not a vegetarian. Not because I don’t like animals or because I don’t care for the Earth. No, because I am a pragmatic person. I eat what my body needs.
If you ask me what my body needs, my standard answer is: vegetables, vegetables, vegetables. But we need more than vegetables. We need some fish, and occasionally even some meat. Some eggs will do, too.
Vegan or vegetarian food is a great way to cleanse the body after too many years of bad nutrition. People who have switched to vegetal food often remember how wonderful they felt that first month after the change - and therefore are reluctant ever to go back to meats. But after a month or two, deficiencies slowly set in.
As a doctor, I am familiar with vitamin B12 deficiency in vegetarians and vegans. It is a big problem. Because without vitamin B12 one gets anemia (low count of red blood cells) and dementia. The brain needs vitamin B12 to function. The sad fact is: If you are vitamin B12 deficient and replenish with that little red pill (or shots from your doctor), your anemia will vanish – but the brain damage is done: The marbles you have lost, you will not recover because dead brain cells don’t come back.
Vitamin B12 deficiency is a pretty good argument for a doctor not to be a rigid vegetarian. But for people who have not seen the effects of a tiny vitamin lacking, it means nothing.
So, here is another argument: We all know that the animal world is divided into two groups: herbivores and carnivores. The first eat greens exclusively, and the others are carnivores – predators that feast on other animals. And, sure enough, there is a third group, the omnivores; they eat everything that comes near their snouts, and pigs and humans are their most notorious members.
Come to think about it: A cow in the pasture munches on grass, solely, right? Wrong! A cow eats tons of insects, caterpillars, ants and butterflies - creeping, crawling creatures that land in their stomachs by accident – and are put to good use. I heard this story (first-hand!): A young, inexperienced farmer kept horses and sheep in one meadow together. After lambs were born in the spring, she found – to her horror – that a horse had smashed a baby lamb’s skull and licked up the brains. This happened not once but twice. She talked with an older farmer, who looked at her with pity and gave this piece of advice: “That’s why you don’t put out horses and sheep together in the pasture.”
Conversely, when a carnivore catches its prey – let’s say a cat a mouse – they eat it whole, including the stomach contents which contain grains. Lions are known for seeking out especially the stomachs of their victims.
This means that the concepts of strict herbivorism or carnivorism are myths: All creatures need both sources of nutrition (albeit in different proportions) – and seek out what they lack.
On our planet Earth, we get our energy from the sun, and from the plants that convert sun energy into sugar and starches – that is how we are nourished, by photosynthesis. Interestingly, carnivores usually don’t hunt other carnivores; they prefer herbivores. Why? Because the meat of herbivores has been grown on an herbal diet. Even carnivores cannot get too far away from the power of the sun in plant materials. And that, by the way, is the reason we usually don’t eat carnivorous cats and dogs but prefer rabbit, cows, game, lambs. And it might be one of the reasons in Jewish traditions for “forbidden” foods: pigs, shrimp, lobsters, and so on – animals that are carnivores or scavengers (eating dead meats). They are too far away from the green source of vitality. And so, by the way, are cattle that are fed corn: No greens strengthening their meat.
One last thought: So, which are the healthiest meats around? Americans seem to think that chicken and turkey are the best – as if chickens and turkey are not animals. From a nutritional standpoint, poultry are only marginally better than beef, for instance; they also contain unsavory animal fats, especially if they are grain-fed and from a commercial source. In a normal supermarket, the healthiest meat actually might be lamb. Lambs are born out in the meadows; they eat grass all their lives, they are not fed grains and are not treated with antibiotics, and so on. Then they are harvested.
Rule of thumb: Eat vegetarian three days a week, fish or eggs three days, meats one day. No deli – ever.
Sorry, if this is a bit graphic. But even if you close your eyes to not see it - the fact is that animals die so that we can eat; meat is not concocted in factories and comes shrink-wrapped and cooled. Let's make sure that the whole operation - from raising animals, keeping them, to slaughterhouses - is run as humanely as possible.
For every animal I prepare in my kitchen – including fish – I say a prayer. To thank this being that died so that my family can be fed. Read More
