Protein head-to-heads · July 2026
Wheat flour (all-purpose) vs Greek yogurt (nonfat): which protein is cheaper?
USDA macros joined to current US grocery prices, reduced to the two numbers that decide it: dollars per gram of protein, and protein per calorie.
Wheat flour (all-purpose) is 3.0x cheaper per gram of protein ($0.012/g vs $0.035/g), while Greek yogurt (nonfat) is the leaner choice at 16.9 g protein per 100 kcal against 2.8 g. Budget favours one, a calorie cap favours the other.
| Food | $/g protein | 30 g protein costs | You need | kcal that come with it | Protein/100 kcal |

| Greek yogurt (nonfat) | $0.035 | $1.05 | 300 g | 177 kcal | 16.9 g |
Full macros, per serving

A week of protein from each
Hitting a common 100 g/day protein target from wheat flour (all-purpose) alone costs $8.16 a week; from greek yogurt (nonfat) alone, $24.50. That is a gap of $16.34 every week for the same protein. In practice you mix sources: the planner computes the cheapest mix for your exact target and calorie cap, live from the same dataset.
Budget says one, calories say the other
Wheat flour (all-purpose) costs $0.012 per gram of protein against $0.035, so it saves $16.34 a week at a 100 g/day target. Greek yogurt (nonfat) answers a different question: 16.9 g of protein per 100 kcal against 2.8 g, which is what matters once calories, not dollars, are the thing you run out of first.
What the calories cost you
Getting 30 g of protein from wheat flour (all-purpose) brings 1060 kcal with it. On a 2,000 kcal day, three servings would be most of your budget before anything else goes on the plate. That is fine when you are eating at maintenance or building, and it is the reason this food falls apart on a cut no matter how good the price per gram looks.
On a cut these are not comparable
Greek yogurt (nonfat) carries 6.0x the protein per calorie that wheat flour (all-purpose) does. When you are eating at a deficit, that ratio is the whole game: the same 30 g of protein arrives with 177 kcal from one and 1060 kcal from the other. The cheaper option stops being cheaper once you count what you had to give up elsewhere to fit it in.
