Why is “per gram” the relevant metric? It should be something more like “per unit ‘satiating power’” (to the extent that such a thing can be defined). If drinking a half-litre bottle of Coke doesn’t make me less hungry than before¹ but eating a cone of ice cream makes me feel full, if I want to reduce my calorie intake it makes more sense to forgo the former even if it weighs several times as much.
Other than due to the water, CO2, and caffeine, which I could also get from a bottle of sparkling water and a shot of espresso.
That makes sense. I think calories per gram is a reasonably good metric, but there are probably much better ones.
I think the principle still holds: low fat or low carb diets work (when they do) because it is a simple way to help a consumer modify their diet using the lowest hanging fruit based on some reasonable logic (i.e. cut fat ‘cuz generally high calories, or cut carbs cuz’ Americans generally eat lots of them). You don’t have to think about it, and once you form the habit, it’s relatively easy to stick to.
I agree with the rest of your comment, but:
