I firmly believe that the mainstream nutrition organizations base their recommendations on outdated, highly flawed science.
Eventually, these guidelines will change. The "experts" will be forced to abandon the low-fat nonsense that is hurting more people than it helps.
There is no excuse to continue to promote a diet that is proven to be 100% ineffective in the long term, when it is clear that there is another way of eating that works much better.
In the above, family physician explains how the low-carb diet is scientifically proven to be much more effective against metabolic syndrome, obesity and type II diabetes than the low-fat diet.
It is important to realize the massive significance of this... because these are the biggest health problems in the world.
Humans have been evolving for millions of years and it takes thousands of generations for any meaningful changes to happen in our genome.
However... obesity, cardiovascular disease, type II diabetes and all the lifestyle-related diseases that are plaguing humans today are relatively new.
Even though some of these diseases existed before, they have reached epidemic proportions in the past few decades.
Some people like to blame these diseases on the fact that humans are living longer and that they are primarily caused by old age.
But teenagers are getting them too, so that idea doesn't make sense.
Given that the obesity epidemic started only a few decades ago, it seems clear that it is caused by changes in the environment.
Some people have pointed the finger at labour saving devices or the increased availability of food, that we're simply eating too much and exercising too little.
Obviously, these things matter somewhat... but the key, I think, is the unhealthy foods that we are eating and the harmful effects they have on the biochemistry of our bodies.
I personally don't believe that any one macronutrient is to blame. There are both good carbs and bad carbs, in the same way as there are both good fats and bad fats.
The hypothesis that carbs per se "cause" obesity doesn't make sense, because many populations have thrived eating (healthy, unrefined) carbs as a large percentage of calories.
However, even though carbs don't cause obesity, studies show that removing them can reverse it.
The cure doesn't have to be the opposite of the cause.
The biggest health problems in the world are the so-called diseases of civilization.
These include metabolic syndrome, obesity, type II diabetes and cardiovascular disease.
Most cases of these diseases are 100% preventable.
The mainstream health organizations focus primarily on treating the symptoms of these diseases.
However, there is plenty of evidence that they can be prevented and even reversed using simple lifestyle measures that involve changes in diet and increasing exercise.
Most of the health organizations tell us to eat a low-fat diet... the same diet they've been pushing for the last 30-40 years.
However, since the year 2002, over 20 randomized controlled trials (the gold standard of science) have been published that clearly show that low-carb diets are (, , ).
These diets focus on removing sugar and starches and replacing them with foods higher in protein and fat.
Despite the propaganda against such diets... they consistently lead to much better health outcomes than low-fat diets, which have actually been proven to be 100% ineffective in the long run (, , ).
Low-carb diets lead to more weight loss and they improve all the major risk factors for disease... including blood sugar, insulin levels, HDL cholesterol, triglycerides, LDL pattern and blood pressure (, , ).
Even though low-carb diets aren't any sort of magical solution to our problems, they are at the very least a whole lot better than the diet that is still recommended today.
What we really need is a paradigm shift. The cornerstone of mainstream nutrition guidelines was the idea that saturated fat raises cholesterol and causes heart disease.
Now that this has been proven to be false, the scientific foundation for these guidelines has crumbled.
Until we see a paradigm shift, these preventable diseases will continue to advance and claim more lives, each and every year.
