Frequently asked questions
What is the AMDR?
The Acceptable Macronutrient Distribution Range — a evidence-based range set by nutrition science bodies for each macronutrient, wide enough to accommodate different healthy eating patterns rather than prescribing one ideal number.
Is going below this range automatically bad?
Not necessarily — some approaches (like ketogenic diets) deliberately go below the AMDR for specific goals. The range reflects a 'works well for most people in most cases' guideline, not an absolute floor.
