What made humans 'the fat primate'?

Interesting side note: I went deeply ketogenic and lost 25 pounds over the first half of the year. I have never been this low, and also, this is the first time I have seen the puckery appearance of excess skin after a loss.
At the time I just shrugged it off. I had done it for health, I’m not a teen any more, I figured it was to be expected. But now, these patches are changing and shrinking themselves. Which means it wasn’t excess skin after all. It was excess body fat, unevenly distributed. In Carnivore circles, it is held to be that this is the source of the excess skin after weight loss problem. If people were able to lose down to where they should optimally be: they would not have so much of this problem. After millenia of agriculture, what do we know about how we are supposed to work? With adolescence, my body changed, I got a weight problem, and it was all hormones and carbs, seems to me. Now I am approaching a body weight that is what I probably should have weighed as a teen. This is a tribute to Jean (cotonpal) who I think was the one who told me, at the beginning of my low carb journey, that goal weights are only suggestions; that I might be surprised. She’s right. I am! |
While it's fascinating to compare how different species store fat, it's also fascinating to compare how different species use fat, and that informs us that different storage methods in different species have usually evolved to ensure that species survival under the most typical survival scenarios. Humans use endogenous fat when food is not plentiful. If it were easier to access as an energy source, and if it were accessed before glycogen, it wouldn't be there during the challenging times we really need it. Fast forward to today's conditions where food is plentiful, the interpretation of what is healthy food is backwards, and the processed food available makes obesity and disease possible because humans weren't designed to be healthy in an environment where feeding is constant and "food" choices include metabolic land mines.
Yes, I would answer, there are ways to enable weight loss, but they don't come in a pill or by targeted gene manipulation, they happen when one transitions eating and the stuff eaten for better compatibility with how the human metabolism and related energy use operates. We can do this naturally. |
My own personal theory.
Fruit and other sugar/carb crops ripen right before the starvation season. The starvation season in temperate climates is winter and in the tropics the dry season. Humans who developed a taste for these fattening foods, liked to overeat them, and also could put on fat quickly had enough reserves to get them to survive the starvation season. Those that did not make it, did not get a chance to pass those genes on. Today's problem is agriculture plus canning, refrigeration, freeze drying, chemical preservation, and fast global freight travel. Those foods are no longer only available right before the starvation season, but are in your grocery store all year long. In January a person in Washington State can go to Safeway and get a ripe apple. That person can get them in July before the local ones ripen too. They are in the store 365 days a year. Add to that the fact that for eons, we have been selectively breeding most fruits and vegetables for taste, and that means high sugar. The original apples were more like modern crabapples than the apples of today. So why are we fat? We eat foods that should be eaten before the starvation season all year long, and in addition, we have eliminated the starvation season. We unknowingly did this to ourselves. That's my take anyway. It's non-scientific, but it seems logical to me. Bob |
I agree, Bob. We didn’t know how it worked and we messed with it anyway.
As always, I blame Ancel Keys. Bad scientist. |
