## The 5 Ranking Dimensions

1. **Protein Efficiency** — Grams of protein per 100 kcal. Measures how well a product delivers protein relative to its calorie cost.
2. **Value** — Price per 10 g of protein, converted across 25 currencies using live FX rates. The real cost of hitting your protein target.
3. **Leanness** — Protein-to-fat ratio. Higher means more muscle fuel, less filler fat.
4. **Low Carb** — Net carbs per serving. Surfaces products that won't spike your macros.
5. **Fiber** — Fiber per serving. An often-overlooked factor in satiety and gut health.

## XRay Score

The XRay Score (0–100) is a weighted composite of all five dimension percentiles, calculated within each product category (bars vs bars, powders vs powders). A score of 85 means the product outperforms 85% of products in its category. Protein Efficiency and Value carry the most weight.
