Making “Low Carb” A Murderer – Part 2 of 2 – Broken from the start

Broken from the start

(This is part 2 of a 2 part series examining a study posted in The Lancet in August 2018 suggesting that low carb diets will increase your chance of dying early. This series will highlight the conduct surrounding the study by the researchers and those who reported on it in the media [Part 1], as well as the technical limitations and flaws of study itself [Part 2].) 

In Part 1, we investigated the social and scientific impact of observational studies and the scientists who report them. Specifically, we looked at this study published by The Lancet Public Health: Dietary carbohydrate intake and mortality: a prospective cohort study and meta-analysis 

The key takeaways were:

  • The Lancet Study is in no way relevant to any modern low carb diet (ie. What the world considers a low carb diet or a ketogenic diet)
  • The review process for submitting scientific papers to journals leaves wiggle room for legitimate papers to have a mix of fact and author interpretation of data, as long as the author uses the correct language to distinguish the two. Sometimes this can lead to both misinterpretation of theory as fact by readers (including media outlets).
  • Scientists (researchers in general) are humans, at the end of the day, with  career, personal and team based motivations. Whether they believe they are doing the right thing or not, their motivations might add an unwarranted bias into scientific literature.
  • Everyone should learn to examine studies from various angles in order to come to their own conclusion. Don’t just listen to MY interpretation of it. Try to consider potential motivations of the authors, spot misleading information and behavior, acknowledge your own own biases as a reader, and maybe even try your hand at analyzing the technical details of a study.

In part 2, we will be doing just that. We will critically look at how the study was designed and how the author’s interpreted the data. Here are some of the points we will touch upon:

  • Review of what an epidemiology study’s actual purpose is
  • Where the Lancet study’s data came from
  • Whether or not their data is reliable
  • The supposed impracticality, suggested by the author, of directly studying low carb diets against mortality
  • The real long-term effects of low carb diets in contrast to all other diets

Making “Low Carb” a Murderer – Part 1 of 2 – Mischief & Manipulation

(This is part 1 of a 2 part series examining a study posted in The Lancet in August 2018 suggesting that low carb diets will increase your chance of dying early.

A comprehensive guide on spotting shoddy science, by example.

On August 16, 2018, The Lancet published a paper, titled Dietary carbohydrate intake and mortality: a prospective cohort study and meta-analysis 

Immediately, people started reaching out to me with links from news sites saying things like “New study finds that popular low carb diets could shorten life.” Before reading the study, I already knew what kind of study it was… I considered this my call to action. Although the world is more open-minded than ever towards reconsidering stale public health recommendations, it’s evident that there is still a need for guides that can help keep minds open and progress on track.

This is my analysis and response towards the study and the researchers who were involved. This is my attempt at teaching the average Joe/Jane (maybe that’s you) to critically assess studies for themselves and come up with their own takeaways.

The Ketogenic Diet and the Silent Observer

It’s been almost 5 years since I’ve touched this blog.

Why now? Let’s take a step back.

I started my ketogenic journey way back about a decade ago. If you’ve read my article “Journey to Blogland”, you have the low-down of where my dieting story began. I’ve been varying degrees of curious, hopeful, skeptical, downright obsessed, underconfident, overconfident, and everything in between for the last 12-14 years.
