Comparison

THE FAD vs. Keto

A rigid macro framework vs. a flexible inflammation score — and why they aren't actually in competition.

Keto asks you to restructure your entire diet around a macronutrient ratio. THE FAD doesn't require any specific diet at all — you can eat keto, vegetarian, Mediterranean or anything else, and THE FAD simply scores the inflammatory signals within whatever you're already eating.

DimensionKetoTHE FAD
Core ruleVery low carbohydrate, high fatNo food is banned — quality and pattern matter more than macros
FlexibilityStrict macro ratios required to stay in ketosisFlexible — any eating style can score well or poorly depending on quality
Sleep, alcohol, exercise, stressNot part of the frameworkAll tracked and weighted into the score
SustainabilityCan be hard to maintain socially and long-termDesigned for realistic, imperfect, everyday tracking

Can you do both?

Yes. A well-formulated keto diet — built around vegetables, quality fats and unprocessed protein — can score well on THE FAD. A poorly-formulated one heavy on processed meats and low on fibre may not. THE FAD doesn't take a side on keto; it just shows you the inflammatory cost of how you're doing it.
