      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.

          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.

              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:

              They refer to actual research I could not yet access due to paywalls. I will try to find it.

                  I think 4kg over 3years is a huge difference for many people. Not for morbidly obese maybe. Anyway, here it matters that difference exists.

                  There are many ways to make this difference in energy balance, by changing the kind of food eaten, while keeping the same intake volume, by changing the intake volume, or by adding an additional activity, like brooming.

                  Reducing intake by 100kcal by changing volume while maintaining composition is always going to be carbon wasteful. Do we agree on this?

                  There are many advisable ways to reduce the carbon effect. By changing the kind of food eaten, for sure. But also, but replacing manual brooming with less carbon-consuming process. One way does not cancel the other, does it?

                  By the way, we should be clear that instead of brooming one should not go for a run on something. Conversely, replacing some of the health-motivated physical activity with brooming is not a bad idea at all, that’s a large part of the reason I still do it. Still, both sport and manual brooming are somehow wasteful.
