BMJ Stands Behind Nina Teicholz’ Critique of the US Dietary Guidelines


Here’s another victory for science over dogma. Today, the British Medical Journey has again decided to stand behind science writer Nina Teicholz’ peer-reviewed study from 2015, in which the conclusion was that the American dietary guidelines were founded on a weak scientific foundation, and still fail to be up-to-date with the best science.

Teicholz’ article was heavily criticized by old-school scientists – and 180 angry ones even demanded that the BMJ should retract it. After two independent experts reviewed it again, they have concluded that it is “within the realm of scientific debate”:

We stand by Teicholz’s article with its important critique of the advisory committee’s processes for reviewing the evidence, and we echo her conclusion: ‘Given the ever-increasing toll of obesity, diabetes, and heart disease, and the failure of existing strategies to make inroads in fighting these diseases, there is an urgent need to provide nutritional advice based on sound science.’
– Fiona Godlee, BMJ Editor in Chief

Is It Insulin or Calories that Make Us Gain Weight?

4.6 out of 5 stars5 stars78%4 stars13%3 stars4%2 stars0%1 star3%132 ratings4,574 views
What really matters for weight loss? Calories in and calories out, or are our bodies’ weight carefully regulated by hormones, such as the fat-storing hormone insulin?

In this presentation from the 2015 LCHF Conference in Cape Town I describe why the second explanation – about hormones – makes much more sense. And why the first one – about calories – is a simplistic description that completely fails to address the cause of obesity.

Is Gary Taubes Vindicated?


Gary Taubes, one of the true pioneers of LCHF and best-selling author of Good Calories, Bad Calories, was publically ridiculed in 2002 for writing that obesity isn’t about a caloric imbalance, and that fat is not dangerous.

Fourteen years later, Taubes is still somewhat of a heretic. However, slowly but surely, at least some of his ideas are entering the mainstream. Has Taubes even become vindicated? Here’s a new and interesting article on the topic by the man himself, about his experiences:

The Vindicated: ‘Nutrition Heretic’ Gary Taubes on the Long Road Back From a Big, Fat Public Shaming

To insist that obesity is caused by consuming too many calories is as inane as it would be to say that poverty, for instance, is caused by earning too little money. It confuses a description with an explanation and is [a] profoundly inexcusable error.

How can we change public health policies around the world? What natural industry allies does the LCHF movement have? And what mistakes can we not afford to make?

Antonio Martinez, JD, answers all these questions in this talk from the Low Carb USA conference, and presents a very different angle on the challenges which we face.

Martinez has reversed his own type 2 diabetes using a low-carb high-fat approach.

Fasting and Re-Feeding Syndrome

One of the most severe complications of extended fasting, although fortunately very rare, is called the re-feeding syndrome.

Complications with refeeding were first described in severely malnourished Americans in Japanese prisoners of war camps in World War 2. It has also been described upon treatment of long standing anorexia nervosa, and alcoholic patients. It is important to have an understanding of these syndromes if you are attempting an extended fast – usually defined as greater than 5-10 days at a time.

Re-feeding refers to the period of time immediately after an extended fast when you are just starting to eat again. Breaking a fast properly will help reduce the chance of this complication. The two main syndromes are refeeding syndrome and refeeding edema.

davidblaineIn 2003, David Blaine, the magician, emerged from a 44-day water only fast. Opinions abounded regarding whether or not he was cheating, although he was in plain sight the entire time.

Doctors recorded every measurement they could think of afterwards during his hospitalization. He lost 24.5 kg (25% of his body weight) and his body mass index (BMI) dropped from 29 to 21.6. Blood sugars and cholesterols were normal. Free fatty acids were high (expected during fasting).

As he started to eat again, he developed both refeeding syndrome and edema. His blood phosphorus levels fell dramatically. For precaution, he required a short period of hospitalization and required intravenous replenishment of phosphorus. After that, he was fine. Continue Reading →

Carb vs. Fat Metabolism – The Dr. Ted Naiman Hydraulic Model


What happens in your body when you eat fat or carbs? Here are more awesome and simple illustrations from Dr. Ted Naiman, an “über-geeky mechanical hydraulic model of metabolism”.

Above you can see what happens when you eat a low-carb, high-fat diet. Your body gets its energy from the vast fat stores (in blue, to the right).

But what happens when you add carbs? Continue Reading →


How Fasting Affects Your Physiology and Hormones

In order to fully understand fasting and its benefits, it is useful to review the physiology of what happens to our body when we eat nothing. Here’s a brief crash course.


Glucose and fat are the body’s main sources of energy. Glucose is the most easily accessible fuel source for the body. However, if glucose is not available, the body can adjust by switching to fat metabolism, without any detrimental health effects.

This is simply a natural part of life. Periods of low food availability have always been a part of human history and mechanisms have evolved to adapt to this fact of Paleolithic life. The transition from the fed state to the fasted state occurs in several stages. Continue Reading →
