The Dietary Guidelines for Americans recommends that carbs provide 45–65% of your daily calorie intake for all age groups and sexes (1Trusted Source).
According to the Food and Drug Administration (FDA), the Daily Value (DV) for carbs is 300 grams per day when eating a 2,000-calorie diet (2).
Some people reduce their daily carb intake with the aim of losing weight, cutting down to around 50–150 grams per day.
Research has shown that low carb diets can be part of an effective weight loss strategy.
This diet restricts your intake of carbohydrates — including sugars and starches like bread and pasta — and replaces them with protein, healthy fats, and vegetables.
