The Dietary Guidelines recommend 45-65% of daily calories from carbs. For a 2,000-calorie diet, that's 225-325g. Low-carb diets typically range from 20-130g daily.
No. Carbs aren't inherently fattening. Excess calories cause weight gain. Complex carbs (whole grains, vegetables, fruits) provide energy, fiber, and nutrients essential for health.
Simple carbs (sugar, white flour) digest quickly, causing blood sugar spikes. Complex carbs (whole grains, vegetables, legumes) digest slowly, providing sustained energy and fiber.
Net carbs = total carbs minus fiber and sugar alcohols. Since fiber isn't digested, it doesn't raise blood sugar. Net carbs matter most for low-carb and keto diets.
Yes. Carbs 1-2 hours before exercise provide energy. Choose easily digestible options like fruit, toast, or oatmeal. Avoid high-fat or high-fiber carbs right before intense exercise.
Best sources: vegetables, fruits, whole grains (oats, quinoa, brown rice), legumes (beans, lentils), and sweet potatoes. These provide fiber, vitamins, and sustained energy.
