A full two-thirds of Americans are overweight or obese and childhood obesity has tripled over the past 30 years.
While the American agricultural system may be the envy of many less affluent nations, it also has many unintended consequences. One of them is a food system that promotes cheap food largely devoid of nutrients and chockfull of unhealthy ingredients that has caused obesity rates to skyrocket.
If you’re like most people, you probably do not know that there is NO link between agricultural subsidies and nutrition. This is a major part of the problem.
Directly related to this issue is the fact that the government’s nutritional guidelines are in large part mirrored by these same agricultural subsidies, rather than being built upon sound nutritional science.
The original food pyramid created and promoted by the US Department of Agriculture (USDA), told you that the “base” of your diet should consist of grains, pasta and breads, despite the evidence showing that grains, which break down into sugar in your body, promotes fat accumulation and drives insulin resistance and related diseases, including diabetes, heart disease and cancer.
In short, the reason you’re told to make grains the cornerstone of your diet is because that’s what farmers are paid to grow in the US. There’s a lot of it, and it’s inexpensive compared to healthier foods like vegetables, for which few subsidies are offered.
“We’re not going to undo that unless we buy more directly from farmers and buy unprocessed food,” he says.
And I think that’s a crucial point, really. Imagine if food growers could get most or all of each food dollar instead of it being spent on plastic wrappers and food processing! Then they might actually be able to afford growing something other than corn, soy and wheat, which are three of the unhealthiest staples of the processed food industry...
Intermittent fasting: I prefer daily intermittent fasting, but you could also fast a couple of days a week if you prefer, or every other day. There are many different variations. To be effective, in the case of daily intermittent fasting, the length of your fast must be at least eight hours long. This means eating only between the hours of 11am until 7pm, as an example. Essentially, this equates to simply skipping breakfast, and making lunch your first meal of the day instead
A ketogenic diet: This type of diet, in which you replace carbs with low to moderate amounts of high quality protein and high amounts of beneficial fat, is what I recommend for everyone, and is exactly what you get if you focus on the bottom three tiers of my food pyramid
“All sugars are equal, and are okay in moderation:” The science is overwhelmingly clear on this point: fructose and glucose are NOT metabolized by your body in the same way. For example, while every cell in your body utilizes glucose, thereby burning up much of it, fructose is turned into free fatty acids (FFAs), VLDL (the damaging form of cholesterol), and triglycerides, which get stored as fat. Furthermore, the entire burden of metabolizing fructose falls on your liver, which creates a long list of waste products and toxins, including a large amount of uric acid, which drives up blood pressure and causes gout. It also promotes visceral fat. When you eat 120 calories of glucose, less than one calorie is stored as fat. 120 calories of fructose results in 40 calories being stored as fat. As a standard recommendation, I advise keeping your total fructose consumption below 25 grams per day, or as little as 15 grams a day if you have insulin resistance, diabetes, high blood pressure, heart disease or are overweight
“To lose weight, just expend more calories than you eat:” This outdated advice has been shown to be patently false, as not all calories are created equal. In a nutshell, counting calories will not help you lose weight if you're consuming the wrong kind of calories
“Choosing diet foods will help you lose weight:” Substances like Splenda (sucralose) and Equal or Nutrasweet (aspartame) may have zero calories, but your body isn't fooled. When it gets a "sweet" taste, it expects calories to follow, and when this doesn't occur it leads to distortions in your biochemistry that actually lead to weight gain
“Avoid saturated fat to protect your heart:” The myth that saturated fat causes heart disease began as little more than a scientifically unsupported marketing strategy for Crisco cooking oil. Most people actually need about 50 to 70 percent of their diet as healthful fats from organic, pastured eggs, avocados, coconut oil, real butter and grass-fed beef in order to optimize their health
“When it comes to cholesterol levels, the lower the better, to avoid heart disease:” Cholesterol is actually NOT the major culprit in heart disease or any disease, and the guidelines that dictate what number your cholesterol levels should be to keep you "healthy" are fraught with conflict of interest -- and have never been proven to be good for your health. Meanwhile, bringing your cholesterol levels down too low can have significant health ramifications, from mood disorders and violence to, ironically, heart disease
Perhaps one of the most powerful scientific discoveries to emerge in the past several years is that the old adage “a calorie is a calorie” is patently false. The research clearly demonstrates that even if you control the number of calories you eat, if those calories come primarily from fructose and grains, you are at increased risk of obesity and pre-diabetes, which includes both insulin and leptin resistance, fatty liver, high blood pressure and high triglycerides. Insulin and leptin resistance in turn form the foundation for virtually every chronic disease you can think of, including heart disease and cancer.
The answer, therefore, is to turn the conventional food pyramid on its proverbial head, and dramatically reduce or eliminate virtually all grains and sugars, especially fructose. This in and of itself will go a long way toward preventing accumulation of excess fat. However, to be truly effective, you want to make sure you’re replacing those refined carbs with vegetables and healthful fats.
Now you’re entering into a diet that will allow your body to shift from burning carbs to burning fat (or ketones) as its primary fuel. At this point, weight loss is not the only benefit you’ll reap. Compelling research shows that this type of diet, also referred to as a ketogenic diet, is an effective prevention and even treatment strategy for cancer.
Intermittent fasting is another powerful key that will help you transition your body from obtaining the majority of its fuel from glucose stored as glycogen in your muscles and liver, to the fat stored in your tissues. This is one of the most effective ways I know of to burn off excess body fat and eliminate sugar cravings. These are all things that are well within your power to do. Next, I urge you to become involved with changing the system that has brought us to this unfortunate point in our evolution.Growing sprouts in your home is a powerful way to eat very healthy and inexpensively.
Changing your shopping patterns by supporting local agriculture will not only help improve your health, it will also help improve the environment and bring back our rural communities. One way to get involved is to simply buy more food from your local farmers. It is important to understand the impact you have when you spend your money on processed factory food.
