Sure, it’s also just my intuition but trying to lose weight myself and watching friends try to lose weight and 15 minutes of light activity per day does nothing to your energy balance. To actually use weight I have to cycle hours spending like 2000kcal couple times a week. The 100kcal is 5% of your average daily intake. If you’re very active it will even less. Depending on your diet you can excrete more calories then that. Your body will just compensate by adjusting metabolism and you will not have to eat more not to lose weight. With electric bike it’s definitely possible to get in the range when you will have to adjust your diet but I don’t think it’s the case with brooming. Average person will be able to swipe couple days a week without actually eating more, that’s why I think it’s ‘free’. But maybe we have to do some experiments. Do you have a broom?
My weight goes up and down by some 10% every couple of years, I cycle and run (ultramaraphons) and climb and more, and I track and analyse both food and spending with common tools and myself. Which is why I am acutely aware of how at least my body behaves in this respect. And I see people around me who do similar things.
Your point seems to be based on the idea that if it is 5%, it is the same as zero, because metabolism compensates (?). I do not know if this is the case at all or if this is relevant enough to change this 5% number. If this is the case, it is a factor, but it is something peculiar.
Instead, I find, that while a single 10hr trail run spends days worth energy of usual activities, several 5% factors each day, which grow from habits like brooming or taking a walk instead of taking a bus, quickly exceed, or at least strongly contribute to, extreme individual spendings. Also while a long event seems to cause immediate weight loss, it is almost entirely water. So it is a bit hard for me to believe these small spendings are zero. In fact, I find that people often underestimate how simple habits change weekly calorie spending. At least for me, these things make much of a difference in the weight change.
And yes, I have some brooms, and I broom for some 15min a day probably, plus maybe 1h per week.
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.
