The Food and Nutrition Board of the Institute of Medicine recommends eating at least 130 grams of carbohydrates each day. However, when you’re on a low-carb eating plan, you’ll have to scale back -- drastically in some cases. Each diet plan is different, and cutting out carbs too much means that you won’t get the glucose your body relies on for fuel. Because low-carb eating can be dangerous for your health, see your physician for a checkup beforehand.
Daily Carb Allowance
Some plans require you to go through different phases, making you cut back to as few as 20 grams of carbohydrates daily to start. As you continue to meet your weight-loss goals, you can slowly add a few more grams each day. Generally though, the maximum amount of carbohydrates you can have is 100 grams a day while following a low-carb diet.
