Can you quantify how many grams per day "low fat" was for you? Were you consuming eggs, fish, dairy or olive oil? Were you consuming any processed foods?

Actually, the representation of the ancestral diet being primarily meat is incorrect - outside of a few examples where there just weren’t many plants available. Largely, humans ate what they happened upon. Meat was a scarce byproduct of another predators meal. Ie we ate what the big cats left behind. Furthermore, the ultra refined and concentrated foods we now eat didn’t exist until very recently. The amount of sugar…

Humans evolved during the ice age. There were no vegetables in large enough quantities to feed the human brain's massive growth over the past million years. Every single paleolithic cave art depicts animals and hunting techniques. Fossil evidence from millions of years ago show bone scrapes on zebra and reindeer bones in human caves. We evolved to hunt wooly mammoths twice the size of elephants for goodness sake. We…

Cooking is very likely the reason humans suddenly had access to far more calories to support a larger brain. The idea that an organ like the brain that feeds directly on glucose was supported by animal fat and protein just doesn’t hold up to serious scrutiny.

The rise of obesity in the US tracks very closely with the massive increase in cheese & chicken consumption. Sugar consumption actually plateaued years earlier.

So if i switch to tofu and beef, i won't get fat?

I doubt you’d be able to stomach enough tofu to gain weight eating that alone. You’d have to eat 10 cups a day just to hit a maintenance level of about 2000 calories.

It would be a lot easier on fatty cuts of beef at 330 calories for 100g.

> 45 years of eating low-fat high complex carbs Can you quantify how many grams per day "low fat" was for you? Were you consuming eggs, fish, dairy or olive oil? Were you consuming any processed foods?

Main source of my fat intake was from olive oil which was about 2 tablespoons per day (in salads). dairy, in the form of low fat yogurt (1-2 times per week) and eggs (max 2-3 eggs) was always on very limited quantities during the week, With the exception of (small fishes) fish which was only consumed durring the weekends and not more than 3 times per month, no other meat or poultry was consumed in my home. basically the majority of weekdays we were eating dishes with legumes (lentils, kidney beans, chickpea) green beans, peas, olive-oil based vegetable dishes, potatoes, brown rice, whole grain breads, salads which always were present in the table, and of course plenty of fruits. i was basically eating as vegetarian my entire life.

No processed foods, fast foods or sweets were allowed on my home, as a family, we were always very health conscious people.

storing dietary fat works best when you eat carbs, because then your body will run on carbs and carbs will spike your insuline to signal the body to store the fat. Also the insuline spikes and drops make you crave more carbs...

I agree that you won't get fat if you're limiting calories intake, I was just saying all dietary fat isn't always stored and carbs do have an impact in fat absorption.

I'm currently losing the stubborn fat I've had for all my life, just a few pounds I couldn't get rid of: only a low carb higher fat diet has finally worked for me (my BMI is normal).

Also I'm 47 (not the killer)

That was one of the earliest GI measurement studies, though the term GI was invented later.

The problem with GI-based (or GL which takes quantity into account) is that insulin levels at 2 hours isn’t a good proxy for health. One really needs to measure the integral of the insulin level over 24 hours or more (which would involve lots of starving subjects). The best proxy we have for the overall insulin response over time is just net carbs.

Until recently, everyone has lived near the border of starvation, and not had an opportunity to get obese. Since the agricultural revolution, carbs are what we have been able to mass produce, and therefore breed ourselves to greater numbers on. That it probably hasn't been the ideal diet for us is a distant secondary concern. Now that we're finally overproducing food, we actually are getting obese on the carb diet. C…

I think the Venus of Willendorf and her equally thicc cousins are, if you'll excuse the expression, ample proof that some people had an opportunity to get obese long before the agricultural revolution.

Didn't someone put a theory out that the Venus of Willendorf was not venerating the Fat Goddess, but rather what someone sees when they look straight down at their body?

(cuz cave people didn't have good mirrors and all)

There is no such clinical evidence. For example, the Sami of North Scandinavia have a 40% lower cancer rate than Swedish people do (who are pretty healthy by Western standards), despite getting the bulk of their calories from reindeer meat. https://www.ncbi.nlm.nih.gov/m/pubmed/19186763/ The modern cow is not fundamentally different from the ancient Aurochs, or reindeer or bison that used to be consumed in large quan…

Diet has relatively little influence on cancer. Diseases much more closely correlated with diet like diabetes and atherosclerosis are most effectively prevented with a plant based diet. Tribes like Inuit and Masai that eat mostly wild meats show advanced atherosclerosis at early ages and suffer from short lifespans. Of course if you're eating supermarket meat then your diet is nothing like any kind of ancestral hunte…

I'd love to see your clinical research cited sources.

Meanwhile meat has not changed much at the cellular level in tens of millions of years. The only fundamental difference between modern meat and ancient meat is that our ancestors ate the whole animal, organs and all, and that's relatively rare in modern American diet.

Cooking is very likely the reason humans suddenly had access to far more calories to support a larger brain. The idea that an organ like the brain that feeds directly on glucose was supported by animal fat and protein just doesn’t hold up to serious scrutiny.

The brain is incidentally 60% fat. And all the glucose the brain requires can be synthesized from lactic acid. There are entire societies that live off of 99% meat. They live their entire lives with almost no vegetable intake whatsoever, and their brains develop and function perfectly normal. In contrast, consuming too much glucose can wreak all sorts of havoc on the brain, spurring excessive consumption, type 2 diabetes, and has been linked with Alzheimer's.

There are all sorts of theories!

Olga Soffer points out that the woven clothing on the figurines is often incredibly detailed, and suggests they may have been some kind of fashion doll [1]. Mandy Weston speculates that they may be bobbins used for weaving [2]!
