A Simple Hack to Tell If a Food Is Actually High in Protein

I recently came across this protein trick and wanted to see what you all think.

Take the grams of protein per serving and add a zero to it. If that number is greater than or equal to the total calories per serving, it’s supposedly a high-protein food.

For example:
Tuna – 16g of protein, 110 calories. Add a zero → 160. Since 160 is greater than 110, it qualifies as high protein.
Kodiak Pancake Mix – 15g of protein, 220 calories. Add a zero → 150. Since 150 is less than 220, it’s not as protein-dense as it might seem.

In theory, this seems like an easy way to tell if something is actually high in protein or just high in calories with protein—but is this really a good measure? Would love to hear your thoughts!
