Carbohydrate Intake Calculator (AMDR)

Your carb range at the accepted 45–65% of calories, with the 130 g brain-minimum explained.

At 45% of calories (g/day)
At 65% of calories (g/day)
RDA floor (brain glucose) (g/day)

The 130 g RDA isn't an endorsement of any diet — it's the average glucose the adult brain consumes daily, which the liver can also synthesise from protein on lower-carb plans. Within the wide 45–65% fence, carb quality (whole grains, dal, fruit vs refined flour and sugar) predicts outcomes far better than the percentage.

Formula

range = calories × 45–65% ÷ 4 kcal/g; RDA = 130 g
Sources: Institute of Medicine — DRI 2005 (carbohydrate RDA and AMDR); Reynolds A et al., Lancet 2019 — carbohydrate quality
