Negative Press

There’s been a slew of negative press in the last few months calling fad diets out for being negative among other things. The other issue I have is lumping the Keto lifestyle in with other diets without doing the proper due diligence.

I was sent an article recently that quoted a prominent American cardiologist as saying that the Keto lifestyle can increase the risk of cardiovascular disease (CVD) and all-cause mortality. (For reference)

I generally steer clear of these types of articles because the people like this specific cardiologist who ran the American College of Cardiology will generally adhere to the standard american diet view and find a way to down something that is low carb.

He mentions the Lancet study completed and published in Aug 2018. Here’s a rebuttal arguing that the science is flawed: Zoe Harcombe is an incredible resource and she dissects the science of studies like this with such finesse. I truly admire her dedication. Back to the flaws; One of the reasons that Zoe Harcombe states is the reliance on people reporting their own food intake and not being strictly Keto which is 70%+ of fat. There is strong science that says that 30-60% fat is not good for you which is why being Keto is defined as staying above 70%. You do not enter a state of nutritional ketosis below 60% fat and therefore do not reap the benefits of such a state.

The other study he mentions is actually just a review study of 17 others. Most of the data they’re analyzing is referring to Low Carb and High Protein diets. The accepted percentage to deem something as “high” is above 33% of the caloric intake coming from a specific macronutrient. That would mean these people are eating at least 33% of their calories in the form of protein which is not suggested on Keto either. It should be around 20-25% when Keto which is considered a moderate protein intake.

Basically, Keto ends up getting lumped into anything that is “low carb” where low carb essentially can mean anything that is less than 50% of calories from carbs. This is the danger when reading anything that refers to a scientific study measuring results including a low carbohydrate diet. It is very important to review their methods and data. The conclusions of the study and the interpretation of a writer summarizing the study may not always jive.

I would encourage everyone to take some time to read up on the topic and definitely question articles that come out until you’ve taken the time to really look at the studies they are referencing.
