Science Supports Carb Wars
This is an adjunct to my article on the Arclein Diet which I posted one before. An unemphasized assumption to that diet was a low carbohydrate intake. This article reminds us just how important carbs are too outright obesity.
This suggests a modification to our diet for folks who are suffering obesity and are scaling way over the 125% of weight optimum.
As an example, an ordinary three squares a day with little carbs will take a natural person weighing 180 pounds up to a stable 225 pounds. All weight over that level is arguably been supported by the carbohydrate intake of your diet. Eliminating the carbs should allow your weight to drop back to the 225 level while never going hungry or yet fasting.
For most individuals, the first task is to eliminate carbohydrates as much as possible from your diet. The writer here points out that in his experience, even a little bit of indulgence triggers a reaction. It all means, no sweets at all, no bread, no rice, no grains, no beer, and so on. Meals become eggs, meat, fish and ample veggies, particularly as one is trying to bring oneself back to the 225 mark of the example.
If this sounds a lot like the Atkins diet or the Herbalife approach, you are right.
As an aside, the Atkins book is an excellent study of the underlying science of his approach. His conclusions were always attacked in ignorance but no one ever made any headway against the science. Quite rightly, the critics knew few could properly read and understand the science and reach their own conclusions. Thus they simply promoted outright ignorance to gain their own ends. This is unfortunately the pathway for many so called controversies.
If you are morbidly obese, get bulk from vegetable and eat plenty of protein. I would eat a lot of sardines because of their nutrient load, others like salmon. Tofu works as any fresh meat and fish. Eggs also work well of course. My point is that it is not too difficult to get a protein of choice even if it is loaded with transfats and the like.
The initial problem is to quit eating bread and potatoes in particular. Thus there is little point learning how to fast until you have licked that problem.
For the obese individual, there is two phases in a successful diet. The first is to stop eating carbs and through that lower ones weight to the 125% level. One can practice fasts along the way and one can perhaps add modest amounts of whole grains depending on the impact on the monthly weight loss. At least one will be planning proper carbs in the diet which will be handy once one enters the last phase.
In the last phase, one is fasting for twenty four hours every second day for three full days. Good quality carbs will be welcome at that point and are good to go.
However, when one is first breaking with a carb intake supporting obesity, I suspect it is best to initially try cold turkey to discover what your body is able to do before you add any back in.
Scientists say carbs—not fat—are the biggest problem with
’s diet America

Just in time for the holiday-season blizzard of baked goods comes the news that carbohydrates -- not fat -- are more likely to be responsible for obesity, diabetes, heart disease, and the other ills of modern civilization.
The Los Angeles Times has a detailed report on the growing body of scientific evidence that until now has been treated as nutritional poison: Fat is good, carbs are bad.
"The country’s big low-fat message backfired," Dr. Frank Hu, professor of nutrition and epidemiology at the
of Public Health, told the Times.
"The overemphasis on reducing fat caused the consumption of carbohydrates
and sugar in our diets to soar. That shift may be linked to the biggest health
problems in Harvard School
Remember Robert Atkins? He's the guy who was nearly drummed out of the medical profession for proposing that the way to get slim and stay healthy was to eat lots of meat and fat, and abstain from bread and potatoes.
The Atkins diet struck many as pure craziness. But study after study has shown Atkins more right than wrong. Carbohydrates -- meaning plant-derived foods -- have been directly linked with elevated triglycerides (fat) in the blood; suppression of HDL, the so-called good cholesterol; increased production of low-density lipoproteins (LDL) that damage arteries; weight gain and high blood pressure.
Eating carbs triggers insulin, the fat storage hormone. Over-consumption can lead to insulin resistance, a precursor to Type 2 diabetes.
Put all of these carb-related problems together and you have what medical researchers dub "metabolic syndrome." According to the Times, 25 percent of Americans now exhibit at least three of the major symptoms of the syndrome, which include elevated triglycerides, low HDL cholesterol, fat bellies, and high blood pressure.
Now, oversimplification runs both ways. Not all fat is "good": the fat from feedlot beef and factory-farm pork and chicken, which are fed loads of carbohydrates, has a different nutritional profile, higher in heart-disease-linked Omega-6 fatty acids, than those that eat their natural diets and forage on pasture, which are rich in Omega-3s. (The Eat Wild website collects the scientific literature on the differences.) And not all carbs are "bad": complex carbohydrates from whole-plant-based foods cause less of a spike in blood sugar than do refined carbohydrates, i.e. processed foods.
Says Dr. Walter Willett, chairman of the department of nutrition at the
of Public Health:
"If Americans could eliminate sugary beverages, potatoes, white bread,
pasta, white rice and sugary snacks, we would wipe out almost all the problems
we have with weight and diabetes and other metabolic diseases." Harvard
I should know: I've lost a ton of weight in my middle age and turned my cholesterol readings around by giving up carbs and embracing a diet heavy in pastured meat, eggs, and cheese. I still enjoy salads and green vegetables out of our garden. But I blow up like a balloon if I try even a little dessert. I can't eat bread. Beer is strictly taboo.
I know it sounds looney, but fat keeps me slim -- or what passes for slim in my universe.
Turns out the only two macro-nutrients essential for human survival are protein and fat. Carbs in the form of grains and sugar are a very recent innovation in evolutionary terms, yet Americans may be consuming twice as much of them as they should, thanks in part to decades of medical advice and food marketing urging us to cut back on fat.
Meanwhile, a growing movement says we should abstain from meat to save the environment. Does this latest science not create a real dilemma for those advocating a more plant-based diet? What does it mean for our Dietary Guidelines for Americans, which place carbohydrates at the foundation of healthful eating? And what about the orange juice, chocolate milk, and sugary cereals that most schools feed kids for breakfast every morning?
Times avoids the question
vegetarians everywhere must be asking: what about whole grains and legumes, the
bedrock of a thrifty, non-meat diet? L.A.
I predict that in 2011, the nutritious-diet wars will shift to implicate spelt and lentils.
