Carb Acceptable Macronutrient Distribution Range (AMDR)

Carb AMDR is 45–65% of daily calories for everyone over 2 years of age, see US Dietary Guidelines for Americans 2020–2025. 

Use our free Key Nutrients RDA Calculator app to calculate your AMDR.

Use our Carb Counter & Tracker:

• to lower carb intake to prevent or manage diabetes
• to support a healthy carb intake based on whole carbs rather than refined carbs
• to support a low-carb, low-carb high-fat (LCHF) or keto diet.

Carb provides fuel (glucose for conversion to ATP) for energy

• Avoid refined carbs such as white flour, sugar & processed foods, which cause blood sugar spikes, insulin resistance and inflammatory immune responses — they promote inflammatory diseases.
• Choose whole carbs (wholegrains, vegetables, fruits, legumes), which stabilize blood sugar and feed healthy gut bacteria — they protect from inflammatory diseases.
