Overweight means you live longer. - POSTED ON: Nov 09, 2015

Why being 'overweight' means you live longer: The way scientists twist the facts. by Dr. Malcolm Kendrick, M.D. I have been studying medical research for many years, and the single most outstanding thing I have learned is that many medical "facts" are simply not true. Let's take as an example the health risks of drinking alcohol. If you are a man, it has virtually become gospel that drinking more than 21 units of alcohol a week is damaging to your health. But where did the evidence to support this well-known "fact" come from? The answer may surprise you. According to Richard Smith, a former editor of the British Medical Journal, the level for safe drinking was "plucked out of the air". He was on a Royal College of Physicians team that helped produce the guidelines in 1987. He told The Times newspaper that the committee's epidemiologist had conceded that there was no data about safe limits available and that "it's impossible to say what's safe and what isn't". Smith said the drinking limits were "not based on any firm evidence at all", but were an "intelligent guess". In time, the intelligent guess becomes an undisputed fact. On much the same lines, we have the inarguable "fact" that being overweight is bad for your health. I should say that, by definition, being "overweight" must be bad for your health – or we wouldn't call it overweight. But we do not define overweight as being the weight above which you are damaging your health; it has an exact definition. To be overweight means having a BMI of between 25 and 30. Not as bad for you as obesity, but still damaging. Why else would all hospitals and doctors surgeries have BMI charts plastered on the wall with little green squares, orange squares and red squares? Green is normal weight, orange is overweight and red is obese. Even Wikipedia confirms this: "The generally accepted view is that being overweight causes similar health problems to obesity, but to a lesser degree. Adams et al estimated that the risk of death increases by 20 to 40 per cent among overweight people, and the Framingham heart study found that being overweight at age 40 reduced life expectancy by three years." You can also find papers in prestigious medical journals such as the Journal of the American Medical Association (Jama) with the following headline: "Excess deaths associated with underweight, overweight and obesity." That certainly suggests that overweight is bad for you. However, if you look more closely at the paper in Jama, we can find these words: "Overweight was not associated with excess mortality." (My italics). Perhaps more extraordinarily, wha...

End of the Line - POSTED ON: Aug 18, 2015
At this moment I feel like I’ve arrived at the end of the line. As a 5’0” tall, “reduced obese” sedentary 70 year old female, my weight continues to creep upward, no matter what macronutrients I eat or don’t eat; no matter how small I keep my portions; or how hard I work to keep my calories low. This last calendar year I continued with my best efforts at recording every bite taken in a computer food journal, every single day. Sometimes I ate large amounts of food, and sometimes I ate tiny amounts of food. Sometimes I ate a “balanced diet” and sometimes I ate “low-carb; sometimes I ate “high-fat, moderate protein, low-carb”; sometimes I worked to keep my calories around 1000 calories per day; sometimes I worked to have only two 5-bite meals of whatever. My computer eating records show that my overall 365 day calorie average was about 780 calories per day. That number was the total of all my big eating days combined with my small eating days, divided by 365 days. At this point in my life, I am elderly, and although I am in excellent health overall, I have developed a problem with my right hip which restricts my activities, and I lack the ability to do physical “exercise” except for brief periods of slow walking. However, over the past ten years I’ve run many extensive personal experiments on how various exercise affects my own bodyweight, and the results have proven to me that however much or however little I exercise has almost no effect. Apparently my metabolism adjusts down to keep me from dropping weight during periods when I engage in heavy exercise… however it does NOT adjust up to keep me from gaining weight when my food intake goes up whether with or without exercise. During most of this past year, I’ve weighed in my mid-130s - which gives me a BMI in the “overweight” range. During the past 9 years I’ve worked and worked on maintaining my large weight-loss, and tried to drop as low as possible inside the “normal” BMI range. The middle of a “normal” BMI range is, for me, 115 pounds. I struggled to drop and stay below that number for the first couple of my maintenance years, without success, then … while continuing consistently with my ongoing struggle at a food intake averaging around 1050 calories daily … my weight began climbing. Instead of bouncing within a 5 pound range between 110 and 115, it bounced between 115 and 120. Then despite a few more years of working hard to drop back to those lower numbers, my weight climbed to bounce between 120 and 125; then over more time, while eating even fewer calories, and additional exercise, my weight climbed to bounce between 125 and 130; then between 130 and 135. This past several months, my weight has been bouncing between 135 and 140. There appears to be no end in sight. This has been happening over a 9 year period. Since my activity cannot...
Does Fasting Make You Fat? - POSTED ON: Aug 01, 2015
Does Fasting make you fat? by Brad Pilon
If I remember correctly, the FTC views the use of animal research in supplement advertising to be one of the most heinous advertising infractions, right up there with Photoshopped before and after photos. Why? Because they believed that due to the lack of transferability of animal research to humans, doing so would be intentionally misleading the customer as to the potential benefits of said supplement. Even the most ‘fly-by-night’ ethically-devoid supplement companies do not use animal trials in their marketing for this reason. Keep this in mind when you see journalists and bloggers reporting on the latest mouse research, using it to create clickbait style articles about human diet, nutrition and weight loss. Alright, now that I’ve said that, lets get to that article that appeared on Yahoo suggesting that skipping meals will actually make you fatter. It was an animal study, using mice. We know that mice are extremely sensitive to fluctuations in both body weight and meal patterns. They are very small animals, and without getting too technical I’ll just say it’s well known in the scientific community that many parts of metabolism scale with size. For 5 days the mice in the diet group were given half the amount of food as the control mice, and all of the food was provided in one meal per day (that’s why it’s being referred to as a ‘fasting study’). After 5 days of dieting the mice were allowed to gorge for 13 days, they were given an amount of food that was the same or more as the control mice, and were still only eating it all in one meal. So what happened? The control mice continue to grow normally, and their weight increased throughout the study, but the fasting diet-restricted mice lost almost 20% of their body weight in the first 5 days of the study. (This should be your first hint that mice are different than humans. If you and I eat 50% of our daily intake for 5 days we’re not going to lose 20% of our body weight – heck, we could do this for a month and we’re probably not losing 20% of our body weight.) Then, the fasted mice were fed 98-122% of the amount of food as the growing control mice, so the fasted mice started to grow… and they grew quickly. If you think about it, they were getting fed the same amount of food (or more) as the mice that were 30% heavier then them… so rapid weight gain (and fat gain) make sense. So end result? Mice who rapidly lost 20% of their body weight and then regained most of that weight by overeating ended up with larger fat cells then the control mice. I’m not sure why this is surprising. They also had worse measurements of a bunch of health markers… again not surprising. I’m not sure how much the eating cycle mattered here. Again, as I stated earlier, mice are really sensitive to eating patterns so it probably did play some sort of role, but rapid weight loss then overfeeding causing increased fat stores and messed up glucose control isn’t surprising.
The Real Deal on Maintenance After a Large Weight-Loss - POSTED ON: Apr 12, 2015
My own lifetime of observation and personal experience tells me that the following article is “The Real Deal” on the issue of maintenance of a large weight-loss - including long-term maintenance. By “The Real Deal”, I mean genuine, authentic, true, exact, trustworthy, and clear. For those who don’t know, for the past 10+ years I’ve been successfully struggling to maintain my 5 ft 0 inch elderly body at a “normal” BMI after years of “morbid obesity”, through a great many different dieting methods. More information is in ABOUT ME as well as in many articles about my Status in the ARCHIVES. I will be writing more about my personal weight and calorie details at the bottom of the following article: You Should Never Diet Again: The Science and Genetics of Weight Loss To maintain a new weight, you have to fight evolution. You have to fight biology. And you have to fight your brain by Dr. Traci Mann .. Excerpted from "Secrets From the Eating Lab". (2015) I’ve given you the bad news: diets fail in the long run. Now, let’s try to understand why. In social psychology we often say that if you find that most people behave in the same way, then the explanation for their behavior has very little to do with the kind of people they are. It has to do with the circumstances in which they find themselves. For example, most students in class raise their hands and wait quietly to be called on before speaking. It’s not that they are all timid or overly polite types of people. It’s that the classroom setting is sufficiently powerful that without really thinking about it, nearly everyone ends up following the same unwritten rules. When we think about people who regain weight after dieting, it’s a similar principle. It’s not that they have a weak will or lack discipline, or that they didn’t want it enough, or didn’t care. It’s about the circumstances in which they find themselves, and the automatic behavior that is provoked by those settings. In other words: if you have trouble keeping weight off, it is not a character flaw. When it comes to keeping weight off, a combination of circumstances conspires against you. Each one on its own makes it difficult, but put them together and you are no longer in a fair fight. One circumstance that makes things hard is our environment of near-constant temptation. Two others are biology and psychology. I realize it may seem odd to you that I am calling these things “circumstances,” but, like...
