CLINICAL EVIDENCE & GUIDANCE

Frequently Asked Questions

Why are food labels standardly set to 100g?

International Codex Alimentarius regulations mandate 100g or 100mL standards so consumers can compare nutrient density between competing food products without package bias.

How does the portion scaling formula work?

Multiplication factor = Weighed Serving (g) ÷ Reference Serving (g). Each nutrient (calories, protein, carbs, fat) is multiplied by this scaling factor.

Why is weighing food in grams better than using cups or spoons?

Volume measurements like cups or spoons have up to 40% margin of error due to settling and packing density, whereas a digital gram scale is exact.
