Find your recommended daily carbohydrate intake based on your energy needs and dietary guidelines
Carbohydrates are the body's primary energy source, and the Dietary Guidelines for Americans recommend that 45-65% of your total daily calories come from carbohydrates. This calculator estimates your Total Daily Energy Expenditure (TDEE) and then calculates carbohydrate needs at three common intake levels within the recommended range.
BMR is calculated using Mifflin-St Jeor, then TDEE = BMR × Activity Factor. Carb grams at each percentage = (TDEE × percentage) ÷ 4, since carbohydrates provide 4 calories per gram.
Yes, physically active individuals generally benefit from consuming carbohydrates at the higher end of the recommended range (55-65% of calories). Carbs provide the glycogen your muscles need for energy during exercise and aid in recovery after intense workouts.
Both approaches can be healthy depending on individual needs and food choices. The quality of carbohydrates matters more than the quantity. Whole food sources like fruits, vegetables, whole grains, and legumes are preferable to refined sugars and processed grains regardless of your total carb intake.
