Yeah, they are very physically active and they simply don't have enough food to get overweight ("intermittent fasting was part of the culture, not because it is fashionable but because of food scarcity" - from the article). No special diets, no special exercises. Very healthy hearts. And life expectancy about 50 years...

Somehow this reminds me of aquarium fish. One of the most common causes of death is overfeeding. In their natural environment they never have too much food, so their instincts are to eat as much food as they can fit inside their bodies. And then some.

Which just goes to underscore what I've always advocated: I don't care who you are, or what ailment you've got. If I put you on a desert island and provided you with only health food you had to forage for you'd lose weight. The fast food restaurant is the greatest curse on American culture in the history of the nation.

We are fat, fat, fat, with no end in sight. Saw a mom feeding her obese 8 ~ year old son a caffe latte moch choca yah yah da da. And she had one too.

BP of 106/60 at 73. High carb, moderate protein, lacto-ovo-pisco diet. Other than not eating meat, no particular reason, I just eat what makes me feel good. I don't count anything except TSS. Main thing is don't eat too much, eat natural, organic foods, wide variety. Ride lots. Lift weights some. Enjoy being alive.

I wouldn't limit criticism to fast food - all restaurant food in the US is terrible in that it caters to the decadent. Way too much food, almost no vegetables, low quality fats. My wife and I split a restaurant meal and that's not really satisfactory either because it's still too much bad stuff, not enough good stuff. We very seldom eat anything but our own cooking. I look at a restaurant plate and think, "My god, one person is supposed to eat this stuff?!" Horrible.

I think it's a little short-sighted to only look at diet in terms of carb's, fat and protein. You have to look deeper into each and see what other nutrients it's bringing with it.

None are uniquely bad for you, they just either have the nutrients your body needs, or they don't. So I try to eat more of the stuff that's more nutrient dense per Calorie and ignore the fat, carb or protein proportions of my diet.

For cycling, I do concentrate on consuming mostly carbs during the ride. After the ride I'll continue the carbs and add in some protein for another 20 to 30 minutes before going back to normal stuff.

Well these are the maro-nutrient so they are the most important in our daily diet. Actually, it is possible to survive without carbs, but it would be more difficulty and generally unhealthy to live long without at least supplementing many of the valuable vitamins and minerals most of them contain.
