Why existing efforts to combat childhood obesity are bound to fail. By Gary Taubes | hi... - 0 views

  • For the last 60 years, physicians and public-health authorities have been giving that exact same advice to obese people—children and adults—with little or no success
  • The subjects experience modest weight loss (maybe nine or 10 pounds in the first six months), and then they gain the weight right back. Weight loss doesn't last
  • The researchers enrolled nearly 50,000 mostly overweight or obese women into the trial, chose roughly 20,000 of them at random, and instructed that group to eat a low-fat diet, rich in fruits, vegetables, and fiber. These women were given regular counseling to motivate them to stay on the diet. If we believe what these women said they were eating, they also cut their average energy intake by well more than 300 calories a day

  • After seven-plus years on the diet, these women lost an average of one pound each6 (PDF). And their average waist circumference—a measure of what the diet-book authors like to call "belly fat"—increased
  • whatever weight these women lost was not fat but lean tissue—muscle
  • Prior to the 1960s, clinicians used to argue that making an obese person exercise would just make them hungry—they'd work up an appetite—and that's the last thing you want for someone who needs to lose weight.
  • but it certainly speaks to the idea that getting kids to move more is not the answer
  • Making it possible for children to enjoy the benefits of physical activity is a wonderful thing, but expecting that they'll lose weight by doing so is naive
  • how the human body regulates fat metabolism and the accumulation of fat in our adipose tissue
  • why we accumulate fat—or more specifically, why our fat cells store more calories as fat than they release into the circulation to be burned for fuel
  • Insulin levels, for all intents and purposes, are controlled by the carbohydrates in the diet. The more refined and easily digestible those carbohydrates (the higher the glycemic index, as nutritionists would say), the more insulin will be secreted. And the sugars we consume—i.e., sucrose, the stuff we put in our coffee, as well as high-fructose corn syrup—will cause long-term increases in insulin production
  • Every woman knows carbohydrate is fattening: this is a piece of common knowledge, which few nutritionists would dispute
  • We have to tell children (and their parents) that carbohydrate-rich foods—especially sugars and liquid sugars, like fruit juice and soda—are literally fattening.

Fatness leads to inactivity, but inactivity does not lead to fatness: a longitudinal st... - 0 views

  • Conclusions Physical inactivity appears to be the result of fatness rather than its cause. This reverse causality may explain why attempts to tackle childhood obesity by promoting PA have been largely unsuccessful

Kristin Wartman: A Big Fat Debate - 0 views

  • The low-fat trend finally appears to be on its way out. The notion that saturated fats are detrimental to our health is deeply embedded in our Zeitgeist--but shockingly, the opposite just might be true

Coconut Oil - From Villain to Health Food - A Good Appetite - NYTimes.com - 0 views

  • “Virgin coconut oil, which has not been chemically treated, is a different thing in terms of a health risk perspective. And maybe it isn’t so bad for you after all.”
  • And while it’s true that most of the fats in virgin coconut oil are saturated, opinions are changing on whether saturated fats are the arterial villains they were made out to be. “I think we in the nutrition field are beginning to say that saturated fats are not so bad, and the evidence that said they were is not so strong,” Dr. Brenna said.
  • Lauric acid increases levels of good HDL, or high-density lipoprotein, and bad LDL, or low-density lipoprotein, in the blood, but is not thought to negatively affect the overall ratio of the two

  • Casein- and Lactose-Free: During the clarification process, milk solids are removed, leaving the healthy butter fats behind
  • A well-prepared ghee has very little moisture content and is very shelf-stable. You do not need to refrigerate it for 2-3 months if you keep it in an airtight container. When kept in a refrigerator, ghee can last up to a year
  • One tablespoon of ghee can replace up to three tablespoons of oil or butter in your recipe

  • lightly alkalizing effect
  • healing the skin. A small amount of ghee applied to belly button nourishes the entire body and is especially helpful is healing dried lips
  • When you sauté and fry with ghee, there is no hissing, popping or splattering

Ghee - Wikipedia, the free encyclopedia - 0 views

  • Ghee is an ideal fat for deep frying because its smoke point (where its molecules begin to break down) is 250°C (485°F), which is well above typical cooking temperatures of around 200°C (400°F) and above that of most vegetable oils

PaNu - PāNu Blog - Paleo 2.0 - A Diet Manifesto - 0 views

  • until I read Good Calories, Bad Calories (GCBC) by Gary Taubes I still thought that food was just fuel and obesity was always due to bad genes, or overeating, or lack of exercise - the usual suspects
  • Some diseases that are very common today, which we call Diseases of Civilization or DOCs, do not occur with any frequency in native or hunter-gatherer populations until western foods are introduced
  • The background assumption was that cancer, heart disease and obesity are only issues because we live long enough to get them now, and aren’t we lucky for modern medicine?

  • There was really no print equivalent to today’s 24/7 propaganda of pop nutrition via MSN and Yahoo, with perky titles about the latest worthless observational study associating a colorful plant with some tertiary biomarker of health status
  • But in Gary’s book, the descriptions of populations that ate native whole-foods diets, and what happened to them when they started to eat the white man’s food, was totally eye opening and had never been hinted at in my medical school curriculum
  • You all know this one - The vegan menace. Killing infants and robbing adults of their vitality is the ultimate denial of biology. Endorsed by countless brainless celebrities
  • It seemed that the only commonly agreed-upon element among those claiming to invoke what we are “evolved” to eat, might be that cereal grains should not be a predominant part of the diet
  • That we are eating some things we are clearly inadequately adapted to seems certain, but the idea that the dietary bright line is narrow and exists at the 10,000 year mark is a cartoon view not supported by the science
  • In biology, “putative” means an agent that we think is the responsible or active agent, but we are always trying to falsify our hypothesis. We are always looking for evidence that we might be wrong about our agent.
  • The problem in wheat is proteins, not carbohydrate. White flour is dense and highly concentrated in these problematic proteins and antinutrients. Wheat causes problems even in those who’ve been eating it for thousands of years
  • Eat potatoes, sweet potatoes or root veggies for your starch, and stop eating all bread, cookies cakes and other baked goods
  • Fructose is a carbohydrate, but metabolically it is quite different from the glucose that comes from starch
  • the actual requirement is so small it might be better considered a micronutrient
  • As n-3 and n-6 precursors compete for the same enzyme in the eicosanoid pathway, the excess of n-6 in the diet means that n-3 is outcompeted at the enzyme level. The result is a preponderance of inflammatory molecules. Increased cancer and inflammation are both likely related to this
  • Many are aware that 6:3 ratio is important, so they try to compensate by taking fish oil to balance the 6:3 ratio
  • High total PUFA, especially including the highly unstable n-3, leads to oxidative damage to your cells. Your arteries, liver and  other organs don't appreciate extra oxidative damage
  • Stop eating all temperate vegetable oils – cooking and frying oils like corn, soy, canola, flax, all of it. And go easy on the nuts and factory chicken
  • a substantial fraction of nutrition from animal sources is necessary for health
  • Reject the alternative hypothesis of saturated fat or cholesterol as a Neolithic agent – the so-called diet/heart hypothesis
  • Discount the absolute importance of macronutrient ratios in the nutritional transition
  • whole foods diet that includes adequate micronutrients is the best way to eat healthy
  • tubers, root vegetables and other sources of starch can be healthy for normal people
  • A diet that is archaic, in the sense of appealing to the past with both science and history, but not intending to re-enact a battle that has only happened in our imaginations
