The official number, according to people who wear white coats, is around 45 to 65 percent of your daily calories from carbs. If you eat 2,000 calories a day, that’s about 225 to 325 grams. Sounds like a math problem from hell, right? Relax. Think of it this way: it’s roughly three servings of whole grains, two pieces of fruit, and enough vegetables to make a rabbit jealous.
But here’s the kicker—your cousin who runs marathons needs more carbs than your neighbor who “runs” to the fridge during commercial breaks. Your activity level is the real boss here. If you sit at a desk all day, you don’t need the same fuel as a lumberjack or a toddler in a sugar-fueled rampage.
