>That really does seem counter to the low-carb diets that seem to be all the rage among internet communities (also HN). Generally people discussing “low carb diets” really mean managing blood glucose/insulin spikes. So high glycemic carbs, refined sugars, refined carbs. Not all carbs are created equal when we talk about impacts on blood glucose and/or the liver.

Healthy people who are normal weight generally don't need to worry about blood glucose, insulin, liver, or anything else on the molecular level.

> At the age of 45, almost no Tsimane had CAC in their arteries while 25% of Americans do.

> By the time they reach age 75, two-thirds of Tsimane are CAC-free compared with the overwhelming majority of Americans (80%) having signs of CAC.

The article doesn't mention obesity at all. 40% of Americans over 40 are obese[1]. Tsimane obesity rates of adults (>20 years) are 5.6% for women and 1.6% for men[2].

Journalists love writing about dietary composition as if increasing your fish (or whatever) consumption is a magic bullet, but merely changing composition without losing weight is only a moderate improvement (maybe 30% fewer heart attacks, based on that retracted NEJM dietary study[3]).

"The Tsimane get 72% of their energy from carbohydrates. The fact that they have the best indicators of cardiovascular health ever reported is the exact opposite to many recent suggestions that carbohydrates are unhealthy." Refined carbs ARE unhealthy and it's a bit disheartening that they didn't make that distinction in the article.

To add to your point Okinawans once had the greatest life expectancy on Earth and the majority of their diet was carbs too.

Since the introduction of “western diet” post WW2 the majority of their diet is still carbs and yet they now show significant increase of Chronic disease (obesity, heart disease, type 2 diabetes, fatty liver disease and kidney disease) and lowered life expectancy.

Carbs are great if you're actually going to use the energy! The best even! The problem with Western habits is we tend to carb load until we have a tremendous excess of energy which we then use to... sit down for several hours while our body gets busy turning all that unused energy in to fat.

Exactly. Humans are meant to move, and not moving makes us fat. Now that we're extremely sedentary, we literally have no use for the amounts of rice and pasta we consume. We're victims of our own success.

So, what's their average total caloric intake? Hmm... 2400-2700/day[1] which is not in the Lancet article[2], but I did find that in an American Journal of Clinical Nutrition reference[3]. It appears they get lots of exercise, which isn't surprising.

I’d say 8 miles a day has a lot to do with it.

I love the title in the article:

"Is it only diet and exercise?"

Lol. So... they are telling the 'news' that people who eat well, are very physically active, live in close communities with little individual isolation... and they are healthy?

Hold the presses! Seems like BBC had a day where they needed to put in some filler news articles.

This one was quick. It took decades before anyone questioned the war on fat. Looks like the war on carbs is already at that stage.

Give it a few years and we'll start to see the bad affects of too much protein. Mark my words.

People who live a long time don't care about diets. Show me one who did.
