The recommended daily carbohydrate intake varies depending on factors like total calorie needs, health goals, and individual conditions, but general guidelines are as follows:

• For a typical adult consuming about 2,000 calories per day, carbohydrates should make up about 45–65% of total calories, which translates to roughly 225 to 325 grams of carbs per day

• The minimum amount recommended by the Institute of Medicine to meet basic energy needs, particularly for brain function, is 130 grams of carbohydrates per day

• For weight loss, a lower carbohydrate intake is often advised, typically around 100 to 150 grams of carbs per day , which may help reduce hunger and promote fat loss

• Very low-carb diets usually contain less than 50 grams of carbs daily, but these are generally not recommended for long-term health due to limited dietary variety and fiber intake

• People with diabetes or other health conditions may have individualized carb goals, often ranging from 130 grams to about 250 grams per day, depending on their glucose control and treatment plans

In summary, most adults should aim for about 225–325 grams of carbohydrates daily on a standard diet, with at least 130 grams to meet essential energy needs. Lower intakes between 100 and 150 grams may be suitable for weight loss or blood sugar management, but individual goals may vary.
