The ketogenic diet was developed at John Hopkins hospital in the 1920s as a natural cure for epilepsy, when drugs failed. It is a high fat diet restricting carbohydrates. The diet fell out of favor during the anti-saturated fat campaign started in the U.S. and codified into official government dietary advice in the 1970s as a result of the McGovern Report. “Saturated fat is bad” is still official government dietary policy today, due to the influence of the vegetable oil industry which produces their products from the highly subsidized corn and soy bean crops.
The Ketogenic Diet in some form or another has been labeled by many different names in recent times, and started gaining traction again with Dr. Atkins and the low-carb fad diets that became popular about 8 to 10 years ago. Today’s latest fad diet, the “paelo diet” is another example of a diet based on the ketogenic principles.
This diet is not new, however, as it was seen as a therapeutic diet that produced better results than drugs in treating epilepsy way back in the 1920s. Today, the diet is being studied in the medical community with applications to all kinds of diseases. Of course, most of the medical interest in the diet is to try to develop a line of “ketone” drugs to mimic the diet. Ketones, which our body can produce during fasting or “starvation,” are an alternative energy source for those who are insulin resistant. Insulin resistance is increasingly being seen as a major cause of many diseases.
A new report finds fault with the proposed changes, particularly around saturated fat.
Every five years, the U.S. government releases its dietary guidelines for Americans to help men, women and children make the healthiest choices and to provide guidance for national policies and programs regarding nutrition. However, a new report published in the journal The BMJ criticizes the evidence provided for the upcoming 2015 U.S. Dietary Guidelines, arguing that the advice the guidelines use as a foundation is not based in the latest science.

Mice fed a diet high in saturated fat show shifts in their gut microbes and develop obesity-related inflammation.
The types of lipids mice consume affect the composition of their gut microbiota, which influences whether the animals develop obesity-related inflammation, according to a study published today (August 27) in Cell Metabolism. Mice fed a high-lard diet for 11 weeks developed signs of metabolic disease, while mice fed fish oil remained healthy. When the researchers transplanted gut microbes from fish oil-fed mice to antibiotic-treated mice and then subsequently fed the animals lard, the mice were protected from the typical unhealthy effects of the saturated fat.
“This paper, which had nicely controlled conditions, demonstrated that type of fat is really important for shaping microbial communities and their functional dynamics, which in turn impact our health,” said Vanessa Leone, a postdoc studying host-microbe interactions at the University of Chicago who was not involved in the study.
The Cyclic Ketogenic Diet
What constitutes an optimal physique? This is different based on each individual’s unique genetic potential but researchers would agree that we should have a moderate to thin structure and good muscular development.
While many have sought after a thin physique, the mantra of the 21st century is that strong is the new thin! We want to have a good body fat percentage (6-15% for men and 15-30% for women) and have developed well-toned musculature.
Ketogenic Diet and Fat Metabolism:
A ketogenic diet is a very low carbohydrate, moderate protein and high fat based nutrition plan. A ketogenic diet trains the bodies metabolism to run off of fatty acids or ketone bodies. This nutrition plan has been shown to improve insulin sensitivity and reduce inflammation. This leads to improved muscle development and fat metabolism.
The ketogenic diet is built around good fats such as grass-fed butter, coconut products, avocados, nuts/seeds, pasture-raised animal products and extra-virgin olive oil. This diet should also focus on low-carbohydrate fruits, vegetables and herbs as staple components. The fat levels will be between 60-80% of calorie intake.
After decades as a fugitive from ignorant and sometimes corrupt bureaucrats, saturated fats can come in from the cold. A new study fingers trans fats as the real culprit in heart disease.
For decades we’ve been told to cut back on butter, eggs, meat, and cheese for the sake of our hearts. But a new systematic review of the science proves there’s no additional cardiovascular risk from eating saturated fats.
Researchers at McMaster University analyzed the results of 50 observational studies assessing the association between heart disease and either saturated or trans fats.
About one in three Americans now has diabetes or pre-diabetes. That’s nearly 80 million people, the majority of whom suffer from type 2 diabetes – a preventable and, often, reversible condition.
The problem is that many Americans are unaware that the foods they’re eating could be setting them up for a dietary disaster, and this isn’t their fault. Public health guidelines condemn healthy fats from foods like butter and full-fat dairy and recommend whole grains and cereals – the opposite of what a person with diabetes, or any person really, needs to stay healthy.
For the last 50 years, Americans have been told to eat a high complex carbohydrate, low saturated fat diet. Even diabetics have been told to eat 50 to 60 percent of their daily calories in the form of processed carbs!
Research, including a new study involving dolphins, again suggests that this movement away from traditional full-fat foods is contributing to the rising rates of diabetes and metabolic syndrome across the globe.
