Estimate how many carbs (grams per day) you need based on your age, gender, height, weight, and activity level. This calculator uses Mifflin–St Jeor to estimate daily calories and applies the AMDR guideline (45–65% of calories) to recommend a carbohydrate range, a midpoint target, and per-meal suggestions. Works with US (ft/in, lb) and Metric (cm, kg) units. Perfect for planning balanced nutrition, training fuel, or weight-management goals on thekey2wellbeing.com.
