Im not buying this crap
people just want an excuse to be fat
The podgy dad has a better immune system, is less likely to suffer from heart attacks or prostate cancer and, weirdly, is apparently more attractive to women.
I am very skeptical: there are no chunky supercultures.
The on thing I have read is that some fat gives you a reserve if you ever get ultra sick or suffer trauma.
And you know this, how? Have you seen any indications of avg weight/height/BMI/% of body fat among these cultures? I believe the average longest-lived, the Okinawans, were
short, the male averaging around 4'10". I've seen other studies indicating that one possible common attribute of long-lived people past 100 were that they were short.
The thing is - these super cultures books such as the Blue Zones miss a ton of confounding possibilities. If I remember, the one thing about the blue zones identified in the book were that
they had a very mild climate, with a longer growing season, with little, or minimal winter weather, and typically lived in a more remote locale, hilly or mountainous.
Hey, I admit we don't know everything about them. But are you suggesting that the Hunza, Okinawans, Tarahumara, Abkhinasians and Vilcabambans were overweight in any way shape or form just because I can't produce a BMI chart for them? Yes, I've seen pictures of all of them and they do NOT look like modern Americans. Again, it's possible a little fat may help out and perhaps these people had a little fat around their midsection. 4 of the 5 had LOTS of exercise built into their life and 4 of the 5 ate much lower calorie levels than us. Sorry, but no way they look like modern American if that is what you are saying - I don't believe it. And, if you're not saying that, sorry I missed your point.
I'm not saying that they were overweight, but yes, I've seen pictures and not all I've seen were exactly lean machines, some were pretty solid looking folks, much bigger than me for sure. I think we are looking at different cultures here, for example, I'm including Ikaria, Sardinia, and Costa Rica. Not all of these societies were low-fat, in-fact Buettner describe the majority as moderate fat.
Ikarians for example, routinely ate goat milk/cheese/yogurt, olive oil, fish (average 2x a week), and goat meat a few times a month.
The thing is is that they mostly grew their own food, they lived pastoral rural lives, a lot of socialization, a lot of 'mindless' exercise (walking, gardening, working outside), etc.
I think here in the US we've gotten so obsessed (AND stressed) about the perfect diet or the perfect exercise regimen that we've lot sight of the bigger picture.
