  It's popular because it's thermodynamics but it completely ignores that our body doesn't know how to count calories. It only knows how to count macro nutrients and how full your stomach is and palatable food is engineered to avoid the feeling of satiation.

    So much this. Simple self experiment: If you are super hungry, try compare: 1. Eat a bowl of plain steamed rice (in hot water can make it go down easier) - you will very very quickly become satiated and stay that way, probably on less than a small bowl. 2. Eat cake, croissants, stuff that is sweet but not too sweet that you can keep eating it... initially you will stop, but then you will feel hungry again and keep going back for more - you can just keep eating on this stuff, even though the energy density is way higher. The other difference is the speed at which the energy is released, the rice will keep you going through the day, your body gradually extracting energy from it... the cake and stuff get's absorbed almost instantly and so your body has nothing to do but make fat with it - the only way your getting that energy back is through ketosis, which wont happen so long as you keep eating cake. It makes a lot of sense when you start to think about how things have been modified from their natural state, even orange juice is kinda bad in this sense - you can drink a glass of orange juice pretty easily, but there is no way you will be able to eat the number of oranges it took to make it in a single day.

      Not explanatory. White rice has a high GI and brown rice still has a moderately high GI.

>It’s true that people eat more calories today than they did in the 1960s and 70s, but the diﬀerence is quite small. Sources have a surprisingly hard time agreeing on just how much more we eat than our grandparents did, but all of them agree that it’s not much. Pew says calorie intake in the US increased from 2,025 calories per day in 1970 to about 2,481 calories per day in 2010. The USDA Economic Research Service estimates that calorie intake in the US increased from 2,016 calories per day in 1970 to about 2,390 calories per day in 2014. Neither of these are jaw-dropping increases. A 20% increase in food intake seems huge. The data I could find on weight over the same period puts people at only 15% heavier, so this seems to be underselling the difference.

  Increased calorie intake and conversion to fat is the problem but why do humans increase their calorie intake and decide to convert their calories into fat? What button are they pressing that says "I want to be fat!".

    Funny Wild speculation time: In ancient times, when the times got rough, there was always a pre-crisis-phase, aka you witnessed something traumatic, but were not yet impacted by it yourself. Stressing yourself out and triggering that "horror"-phase (movies/ evening news) makes your body go into the "binge" for reserves during crisis mode. Testable Hypothesis: End of the World screaming makes you fat, Continuous bored calm and mental safety feelings make you thin.

      Should be able to see a significant uptick in BMI across the population between 2019 and now if this is the case...

        A correlation between BMI and media consumption would be rather blatantly obvious i guess.

That was an interesting read. I just left this comment in the site (maybe it would interest somebody here too): "Have somebody checked a correlation between breast feeding vs. infant formula in early infancy and hungry feelings in adulthood (or weight as a proxy of that)? It’s just an random idea, but it seems to me that the timeline of increasing obesity and increasing of use of infant formula could be correlated."

  It is an interesting idea, but Australia has a breast feeding rate of around 90% and a large obesity problem
