How many carbohydrates should I eat?

There is no one-size-fits-all amount of carbohydrates that people should eat. This amount can vary, depending on factors such as your age, sex, health, and whether or not you are trying to lose or gain weight. On average, people should get 45 to 65% of their calories from carbohydrates every day. On the Nutrition Facts labels, the Daily Value for total carbohydrates is 275 g per day. This is based on a 2,000-calorie daily diet. Your Daily Value may be higher or lower depending on your calorie needs and health.

Is it safe to eat a low-carb diet?

Some people go on a low-carb diet to try to lose weight. This usually means eating between 25 g and 150 g of carbs each day. This kind of diet can be safe, but you should talk to your health care provider before starting it. One problem with low-carb diets is that they can limit the amount of fiber you get each day. They can also be hard to stay on for the long term.
