If food was sold by the calorie, it might help people make better food choices.
If only people understood you shouldn’t base your eating choices on calories solely. Like, there are SO MANY MORE parameters you should take into account.
Also, well, it’s kinda bullshit for those working manual labour/physical jobs (which where I am are generally paid the least). You get those who are burning through the most calories (construction workers, cleaners, etc) being the least able to afford high-calorie food like carbs, and you can bet your ass that if there isn’t rock-solid and consistently enforced legislation or strong unions helping, their companies won’t step in to help.
