Whether you disagree with putting calories on or not, or whether it’s effective for behaviour change, I don’t see an issue with using calories over protein / carbs etc.
I totally understand “calories aren’t everything” and I’m actually a fan of keto / low carb personally. Not unusual to see me eating full fat cream whipped up in a mousse when I want lose some excess pounds 🤣
But, calories are simple and well understood. Pretty much everyone knows - too many and you gain, too few and you lose. And broadly that is true.
Where I this is helpful, is people can have no idea the total calories in their order. It’s easy to assume that it’s one meal, so no way it’ll be a whole day of calories. Because it’s easy to see a starter, Main and dessert as a single meal. Actually seeing that you could use up two full days worth of calories in one meal can be eye opening.
If you’re someone who is already into keto, carb counting, protein, IF, 5:2, whatever… then you don’t need this info. It’s not aimed at helping you.
