Junk Clickbait Headlines Mischaracterize Interesting Study

Per USA Today: "Low-carb diet linked to early death, medical study suggests"

"Cutting carbohydrates might also cut lifespan by up to four years, according to a new medical study."

Wow - it sure seems like the keto diet contingent has it all wrong... Until you look at the study, here:

thelancet.com/journals/lanp...

"both low carbohydrate consumption (<40%) and high carbohydrate consumption (>70%) conferred greater mortality risk than did moderate intake, which was consistent with a U-shaped association (pooled hazard ratio 1•20, 95% CI 1•09–1•32 for low carbohydrate consumption; 1•23, 1•11–1•36 for high carbohydrate consumption). However, results varied by the source of macronutrients: mortality increased when carbohydrates were exchanged for animal-derived fat or protein (1•18, 1•08–1•29) and mortality decreased when the substitutions were plant-based (0•82, 0•78–0•87)."

So, what we see is that too much animal-based nutrition is what is at fault, and that substituting plant-based protein or fat for carbs does in fact increase longevity.

Interesting article. I like the Lancet and think they publish quality stuff, so I am surprised by the misleading headline.

However, the article linked at the bottom of that article, said, "Such differences in risk associated with extreme differences in intake of a nutrient are plausible, but observational studies cannot completely exclude residual confounders when the apparent differences are so modest."

I periodically log the food I eat for a week or 2 to find out where my calories are coming from and figure I'm about a 75% adherent to Keto, which puts me halfway between a 20% max allowed by keto and the 50% minimum cited in this study. I feel good about my 75% theory.

There's good data going back 30 years supporting calorie restricted diets on longevity.

So, if sugar is bad for PWP, and I think it's the worst thing we can do, then getting 50% of our calories from carbs, seems to me to be too much sugar??

The headline came from USA Today and not the Lancet. I will edit the posting to clarify that.

Both sugar and complex carbohydrates all get lumped together under the same category, which is problematic. Complex carbs do get turned into sugar slowly, but therein lies a huge difference. Simple sugars are absorbed very quickly and wreak havoc with blood sugar regulation.

Not all vegans follow either a low carb or a calorie restricted diet.

Sure.., no need to :)

Then your comment has nothing to do with the subject

May be because I am just a simple vegan with Parkinson's... And regarding this subject I had in mind how we use only plant-based proteins and etc...

But vegans, as a group, do not necessarily refrain from carbs which is the main point being made.

Indeed. Unless a vegan restricts their calories to 85% from Avocados and Coconut oil I can't see how they can go low carb.
