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.

One of the main intriguing things about this group of people is that they do not eat particularly well.

> That heart health is in spite of the fact that they consume between 2,433 to 2,738 calories per day ... strangely, their diets aren’t incredibly healthy, though we can still learn a thing or two from their lifestyle.

Yeah very strange they do a breakdown of what percentages each diet has, but not the overall caloric intake. If you consume 5000 calories a day, it really does not matter how healthy your macros are. I wonder what the results would show if they did a similar study but compared people of similar body compositions. Who has the healthiest population of people with a BMI of ~20.

After a quick Google I found several older articles that do mention the caloric intake of the Tsimané [1]. It is curious that the BBC article left that out.

Another fact about Bolivians ... they are, on average, the shortest people in the world. https://www.worldatlas.com/articles/countries-with-the-short...

Oh! Short stature, mountainous country near the equator - means the least gravity affecting their circulation! Natural heart-healthy situation!

Do astronauts have better hearts? Was this studied in the twins experiement we saw a while ago?

"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.

>Most of the rest comes from family farms growing rice, maize, manioc root (like sweet potato) and plantains (similar to banana)

these aren't refined, but they arguably aren't the healthiest for you

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.

Converting carbs into fat is fairly inefficient. It comes at about a 40% calorie loss. So you can put on fat eating carbs alone but it’s not easy. More often than not we eat carbs together with fat so your body will very happily just directly store the fat and burn the carbs for energy. This is why things like french fries or pizza are so fattening.

But if you eat just proteins and fat, the fat is not stored (see e.g. keto diet)

How can this be explained?

Yeah, comparing with Americans seems designed to overstate the effect. If you instead compared with e.g. some European country where the obesity rate is much lower, it would yield a better idea how the two diets compare if the caloric intake was about the same in both cases.

Short heart-to-brain distance may also predict an ability to handle high G-forces as a fighter pilot. https://fightersweep.com/1411/agsm/

Upper level athletes eat 5000 calories a day just fine, though they tend to have better macros

I’d guess it’s because in that case you don’t produce much insulin which is starting to be called the fat storage hormone.
