On top of that though is you have to get over your intellectual ideas of how much food you think you need to eat.
I know how much food I need to eat in order to survive and maintain a healthy weight. But if I eat that amount of food, I'm still hungry.
Doesn't matter what I eat. I'll eat a diet high in protein and fiber, moderate in fat, and low in sugar and starches, which is supposed to be the recipe to feel full without eating empty calories, but it doesn't work. 16 oz steak paired with an 8 oz portion of green beans or broccoli, and I still get the munchies just 2 hours later.
I should probably go to a doctor and ask about Ozempic or something. I did successfully lose about 50 pounds doing keto and brought my A1C from 6.8 down to 5.4, but I damn near lost my sanity because I was always hungry. I've gained it all back and started to get some of diabetic symptoms again.
if some unknown element was making everyone's internal thermostat aim for more food it would explain a lot.
Science and capitalism have created incredibly delicious foods that are nutritionally lacking, hyper optimized for (against?) our now mis-aligned reward system. In the west, calories are not scarce and the most delcious foods are far from the most nutritious. It will take a long time for our genes to catchup.
Mass producing delicious, cheap, but low nutrition food is profitable. Companies have gotten very good at it. That's the real big change.
we got the abundant food and the largely car bound live cycles and it still kept getting worse for decades after that point. I suppose it could be generations growing up only knowing this and so habituated to it more?
The "public presence" of society has diminished due to the internet. You no longer need to put effort into constantly looking your best because social media helps curate your appearance. Going to Walmart is now so relaxed that you can wear pajamas. Putting on your "best appearance" occurs elsewhere in curated ways (i.e. facebook/instagram posts and careful selfies). You can "partition" your social life so that the people shopping at walmart see pajama-you while the Tinder matches see someone totally different.
