A place to discuss problems of car centric infrastructure or how it hurts us all. Let's explore the bad world of Cars!

Don't follow people you disagree with into multiple threads or into PMs to insult, disparage, or otherwise attack them. And certainly don't doxx any non-public figures.
4. Stay on topic
This community is about cars, their externalities in society, car-dependency, and solutions to these.

In the absence of a flair system on lemmy yet, let’s try to make it easier to scan through posts by type in here by using tags:
Maybe your basal metabolic rate will change because you bike more.
Since you'd have to bike like 30 miles a day for calories from biking to surpass calories from basal metabolism, small changes is basal metabolism will mater a lot
I'm still having a hard time understanding your point. Sure, becoming more fit and replacing fat with muscle may slightly increase your basal metabolic rate but I feel like were onto "I don't use plastic straws" levels of insignificance.
If you're biking a few miles to work each day and this ends up being such vigorous exercise that you increase your basic metabolic rate by 50 calories a day or so, you're still using nowhere near the amount of energy and creating far less pollution than would have been required to drive to work. Small changes in basal metabolism will mean very little.
My point is that measuring energy use from exercise isn't very meaningful since energy use by animals is so complicated. It seems wrong to say that exercising more increases your carbon footprint.
Maybe studies that meaure the effects long term energy in response to increased exercise. But either way, some amount of exercise is necessary for human health. Biking to work instead of running on a treadmill is clearly carbon negative. Or maybe people biking to work will cause them to get a wasteful biking hobby where they buy a new carbon fiber bike every year.
I see.
Well, I think that the take away message here is that, on average, the energy required for a person to ride their bike (ebike or entirely human powered) to work is so small that the signal gets lost in the noise of normal human metabolism, especially if we take peoples' exercise routines into account.
On the other hand, driving to work has a large, easily quantifiable energy requirement. It is very obviously costly and unsustainable.
