The Dietary Guidelines for Americans recommends that carbohydrates make up 45 to 65 percent of your total daily calories. So, if you get 2,000 calories a day, between 900 and 1,300 calories should be from carbohydrates. That translates to between 225 and 325 grams of carbohydrates a day. You can find the carbohydrate content of packaged foods on the Nutrition Facts label. The label shows total carbohydrates â which includes starches, fiber, sugar alcohols, and naturally occurring and added sugars.
In general, how many grams of carbs per day you should consume is probably going to be in between 500 and 800 calories from carbohydrates, and thatâs typically about 150 to 200 grams of carbohydrates per day â 200 is an upper amount and goes as low as 120, which may be ideal for many trying to trim down.
