how many proteins and carbs should i have in a day?
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 Nutrition Facts label shows total carbohydrates, which includes starches, fiber, sugar alcohols, and naturally occurring and added sugars.
Rice University recommends that active adults get up to 1.2 grams of protein per kilogram of body weight and that athletes intending to build muscle mass get up to 1.8 grams per kilogram. A scoop of protein powder has about 20 grams of protein, and a 3-ounce grilled chicken breast has 26 grams.
