So now you’re taking about ‘several 5% factors each day’ which is completely different than 5% per day. Of course that if you keep adding those 5% activities up and get to 20-30% more calories burned daily you will start noticing it. But single 5% activity? I highly doubt it. Metabolic adjustments is a real thing: https://pubmed.ncbi.nlm.nih.gov/15044180/ You can excrete as much as 20% of the calories you consume. Burning 5% calories more can just mean you will shit less often or you will sleep better and use less calories during the night. I really think that the idea that 15 minutes of swiping daily will cause to eat more or lose weight is just silly.
I am talking about the fact that 5% add up, both over a single day and over multiple days, which cannot be neglected since it makes a significant impact over enough time.
You seem to be saying that there is a threshold of spending below which the spending is equal to zero and does not accumulate, right? That would mean that MR adjustment is exactly compensating small increases in energy spending.
Thanks for the link! I read the paper to the best of my ability, I am not a biological kind of scientist, but I do not find an indication in it for this kind of adjustment you are talking about. The main conclusion seems to be that MR adjusts after major weight loss. Even after this adjustment, I would deduce, adding 5% would help to limit weight loss.
Do you have a reference which would support your idea that there is a threshold (I guess you are saying it is somewhere between 5% and 20%?) below which energy spending is exactly compensated by MR and hence does not accumulate?
Seriously, maybe it exists, I just never heard of it.
My statement is based on energy conservation, which is also a clear assumption in the article. The net effect on the intake-spending balance can be modified by MR adjustment, but it just does not seem to work the way you propose it does.
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?
