More About Brown Fat

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. Don’t go there! Read More

Fast Will Not Last – A Step-By-Step Weight Loss Program

Fast Will Not Last – A Ste After politics, I better return to my own turf. My forte is one-to-one talking with on people, not saving the world. Ali - on Roanne Weisman’s blog Own your Health - has asked me this question: How can I lose weight fast? Truth is: Fast will not last. Most common request seems to be: “Now it is May – can you help me lose fifty pounds till September, because I will marry in September.” My answer is always: “No!” Weight loss should be really slow so that the body does not go into survival mode and defies weight loss. As disappointing as this may be, it is the only way to success. Yo-yo dieting has been shown to be especially detrimental to the heart, so don’t even start that process! Here are my rules: • Do not lose more than two pounds per month! • Weigh yourself every morning. • If you inadvertently lose more than two pounds per month, don’t gloat about, and don’t be disappointed if you regain some of that weight. • Once you have lost those two pounds, put your focus on keeping off those two pounds. The real challenge is to not regain any pounds during the month. • Weight loss does not happen by diet alone, and not by sweating hours in the gym. Weight loss comes from a healthy lifestyle. • One of the most important parts of that healthy lifestyle is getting enough sleep. Sleep deprivation leads to high stress hormone levels in the body, which leads to cravings and overeating. • The next day is won the evening before: Prepare breakfast and lunch, and plan dinner for the next day, then go to bed early. Don’t hang around in front of TV or computer beyond your “tired point” – because then you get a second wind and can’t fall asleep. Best bedtime is between 8.30 and 10.00 pm. If you think you can’t do that every night, give it a try one evening per week – and observe the difference in how you feel. • Below is the step-by step program. Take a new step either every week or every month, or when you feel you need to do more for your health, or when the weight loss progress stalls. • The most important question: Is your weight loss goal realistic? If you are of Dutch ancestry, you might never get to be a dainty as many Asians are (only a rule of thumb – there are small Dutch people, and large Asians!). For that look up your BMI - for instance here: http://www.aarp.org/health/fitness/info-05-2010/bmi_calculator.html?CMP=KNC-360I-GOOGLE-HEA-FIT&HBX_PK=bmi&utm_source=Google&utm_medium=cpc&utm_term=bmi&utm_campaign=G_Health&360cid=SI_148921798_7430108821_1. • Your BMI will give you a weight range. If you are small-boned, you should be at the lower part of that range, if you are big-boned, at the higher end. How do you know about your bones? Compare your wrist bones with those of other people to get an idea where you stand. • If you still have a protruding belly, you are not at your ideal weight. • In every meal have some protein and some good fat. Legumes provide protein. • Most important is your intake of vegetables, which should be mostly cooked, especially in the winter. • Cut down on meat to once a week, and do not eat deli and sausages at all. Have some fish – preferably small fish. And here are the weight loss steps: Step # 1: Buy a green leafy vegetable (chard, spinach, kale, dinosaur kale, kohlrabi greens, etc), cook it with olive oil and garlic - and eat it. Step #2: Leave out all soft beverages - including "diet" beverages. Step #3: Drink herbal teas when you are thirsty. Or plain (or filtered) tap water. Don’t drink bottled water. Step #4: Leave out all dairy (cheese, milk, yoghurt, etc). Milk is a highly inflammatory substance, totally alien for people beyond infancy, that leads to all kinds of diseases besides obesity: diabetes, arthritis, depression, cancer, allergies and asthma, heart disease, and so on. Step #5: Buy a root vegetable (red beets, celeriac, turnip, etc), cook in salt water until just soft enough to pierce with a skewer. Serve with olive oil, pepper and salt as a warm salad. Rutabaga, because it is usually waxed, needs to be peeled before cooking. Cut in cubes, boil with a bit of water and pepper and salt. Step #6: Go for a daily walk. Best is during lunch hour, for the anti-cancer effect of light. Ten minutes in the beginning is fine. Go with a friend – so that you may stay with this habit. Step #7: Leave out all sugars. And don’t use any sweeteners. They fool the body into thinking you get sweets – and then your body wants more food. Besides, most sweeteners except stevia carry their own health concerns. Step #8: Find a new vegetable every week in your supermarket – try out what you don’t know (most vegetables are delicious with garlic and olive oil). Some fat is required with all vegetables because otherwise you cannot absorb the vitamin A in them. Step #9: Leave out all grains and starches until you have your ideal weight. Then you might re-introduce some whole grains – but only if you are not regaining. Step #10: Observe how much you are actually sitting during the day. Sitting is detrimental to your health – and of course, we are a sitting culture. Think about ways to move more: Putter in the garden, clean out the attic, walk a dog, play with the kids, ride a bicycle. The German philosopher Immanuel Kant recognized this principle and kept his handkerchief at the other end of the room, so that he had to get up from his desk to blow his nose. Try to come up with your own – and better - movements! Step #11: Stop all margarine, spreads and butter. If you still eat bread, dunk it in olive oil. Step #12: Volunteer somewhere – in a shelter, a soup kitchen, a church, a political campaign, a gardening project, a reading help for youngsters –to get out of the house and do good! P.S. This is a long entry. But it boilds down to two points: 1. Vegetables, vegetables, vegetables - eat more, and more varied! 2. Put more movement into your day - little movements here and there. P.P.S. Recheck this blog - I might add new points as they come up! Read More

The Super Foods … Bunkum

You have read and heard it so often: The Ten best foods, the Five Best Fruits, The Super Foods Without Which You Will Die... Some of the lists contain meritable foodstuffs, often judged by their anti-oxidant contents. Apart from outright scams (brand-names) on those super-food lists, the usual suspects are blueberries (all the berries, really), broccoli, walnuts, spinach, beans, cinnamon (without the bun), almonds, avocados. There is nothing wrong with these foods. But the concept of “super foods” is all wrong. If you eat the same super food again and again, you have a higher chance to sensitize against it and end up with an allergy. Also, you might get an overfill of some phyto-nutrients, and become deficient in others. Not to mention that we have to worry about pollution - you don’t want to eat the same mercury-laden morsels day after day. We were made for roaming the savannah and nibble here and there, all day long. That gave us enough exercise, and rotated our groceries, depending on area and season. Asked about healthy nutrition, I like to say (stolen from realtors who stress “location, location, location”): Vegetables, vegetables, vegetables. Today I want to add: Rotate, rotate, rotate! The point is to eat a wide variety of meats, fish and vegetables, preferably local and in season (less meat, more vegetables!). Having emphasized variety, here are some under–used and relatively inexpensive vegetables: Onions, garlic and all cabbages (broccoli, kale, brocco rabe, broccolini, Brussels sprouts, white, red, Savoy) – eat them often. Summer and winter squash, too. Don’t forget root vegetables: Red beets, carrots, celeriac, daikon, jicama, rutabaga. Assignment: Each time you venture to your local market/supermarket, find one new vegetable! Bring it home and serve it - any vegetable tastes good cooked (but not overcooked!) with olive oil and garlic. Read More
