I've had the epiphany that my body is a living vessel of energy production (and consumption), just like all other energy sources and associated forms of consumption or re-allocation around me.
My body produces sometimes a huge amount of energy (in one form or another - kinetic, heat - even electrical), but it's not being put to use for other things a lot of the time and quite a bit of energy wastage is occurring.
Is there no significant consequence to how we use our bodies' own generated energy - from a resources sustainability point of view - or are there considerations one can put into use in terms of harnessing one's body energy for external power consumption purposes?
It is of course healthy for our own bodies, to expend energy (i.e. to exercise), and no doubt more sustainable to use our own energy to power production of other things like transport (in the way of riding a bike instead of burning fuel, so long as what we ate was more sustainable to produce than the fuel we would consume in the automobile).
But what other ways can one use one's own body energy wisely, and in general what principles / themes can one explore to put it into practice?
Is there even some advantage in being mindful of not taking in too much energy (coming into your body) in the first place? (I.e., not consuming too much biomass resource in the first place?) And to extend that, maybe even more mindful diet and lifestyle (eating more efficiently energy absorption-wise, i.e. having a smart diet for better nutrient, protein and carbohydrate absorption rates, as well as getting good sleep and probably better-balanced exercise), is a relevant factor here? (A poor diet and lifestyle meaning you are a poorer - i.e. less efficient - medium of energy production/consumption?)
