Diet-Fit Rankings
We score every product in our database against the published rules of 10 popular diets, then rank the best high-protein picks for each. Same USDA data, same transparent methodology — pick your diet and see what actually fits.
Scored on calories per gram of protein (≤5 cal/g is elite, like nonfat Greek yogurt and white fish), with a bonus for high absolute protein per serving (≥25 g).

Frequently Asked Questions
What is a diet-fit score?
For each product, we compute a 0–100 score for how well it fits a given diet's published rules — Keto, Paleo, Whole30, Mediterranean, DASH, vegan, and more. Scores come deterministically from the same USDA macros and ingredient list behind every Labelgrade. No proprietary "score brewing"; the rules are documented.
Are these rankings free?
Yes — all ten ranking pages are free to browse. Labelgrade Premium adds the diet-fit scores directly on every individual product fact sheet (so you see all ten diets the moment you open any product), plus the seven advanced diets beyond the three free binary ones.
Is this medical or dietary advice?
No. A diet-fit score tells you whether a food matches a diet's rules — not whether that diet is right for your body. For personal health decisions, especially around diabetes or blood pressure, consult a registered dietitian or physician.
