So all I’m saying it’s not just energy conservation. Human body is not a machine where input=output. Some of the food you eat is excreted unprocessed and your metabolism can just slow down. So if you’re just using 5% more energy per day your body can speed up digestion a bit and get more colaries out of the same food or it can slow down more during the night and you will get a better sleep. There’s a limit to it of course but your body will deal with 5% change without using it’s energy stores.
I hear you, but scientists specifically study how metabolism adapts, for example the study you quote. And, as far as I see so far, they find that the adaptation just does not work like you think it does. You may choose to insist on your intuition despite empirical evidence against it. But I hope you realise this can lead to your expectations, based on this intuition, clashing with reality.
How does it work then? As I understand it depriving body of calories causes it to be more efficient with the calories it gets. What I’m missing? Maybe what you are still missing is that this effect will change depending on amount of calories we’re talking about? I doubt there are studies measuring the effect of 100 calories deficit because it would be negligible. Of course if we get into real diet/moderate exercise the effects will change. Is this why you think the effect is different overall?
Sorry for the long silence.
The adaptation works in reaction to large persistent changes, not small 100 restriction as you are proposing.
This also makes sense intuitively, large changes cause reaction while “slow and steady” achieves long term goals.
There are, apparently, discussions referencing just the 100 reduction effect:
Maybe you’re right, maybe the metabolism changes will not kick in with 100 calories reduction.
Stil, even if all this is true (I mean, no need to get into the paywalled details) we’re taking 4kg over 3 years which in many cases will be totally insignificant. Many people will not start eating more because they lost 4kg. But even if they will then, as this article says, eating 100 calories more doesn’t require actually eating ‘more’ food, just a different one. Get a potato instead of a salad, get different type of bread, or a normal butter instead of ‘diet’ one. Figuring out if those changes are carbon negative or positive would be incredible difficult as they would depend on the specific products you’re changing, where do you buy it and so on but my bet is they will be close to 0. I still think it would take way more than that to offset the carbon footprint of a Rumba.

They refer to actual research I could not yet access due to paywalls. I will try to find it.
No problem, we’re all busy here.
