Most healthy adults do well with about 45–65% of their daily calories from carbohydrates, which is roughly 225–325 g of carbs per day on a 2,000-calorie diet.

Quick Scoop

  • General guideline: Carbs at 45–65% of your daily calories.
  • For a 2,000-calorie diet: about 225–325 g carbs per day.
  • Absolute minimum for brain function: about 130 g carbs per day for adults.
  • Many adults with diabetes are advised to stay near 135–200 g carbs per day , personalized to their plan.
  • Quality matters: favor whole grains, vegetables, fruits, and legumes, and aim for at least 25 g fiber per day as an adult.

How to adjust for your goal

  • Weight loss: many people feel best somewhere around 130–200 g per day, focusing on high-fiber “slow” carbs rather than sugar and white flour.
  • Very active / athletes: often do better toward the higher end of the range (e.g., 50–65% of calories) to fuel training.
  • Diabetes, prediabetes, or other conditions: carb goals should be individualized with a clinician or dietitian; generic numbers may not be safe.

Simple example (2,000 calories)

  • 40% carbs → about 200 g/day
  • 50% carbs → about 250 g/day
  • 60% carbs → about 300 g/day

Quick “good carb” checklist

When you look at your plate, try to make most carbs come from:

  • Whole grains (oats, brown rice, whole‑wheat bread).
  • Vegetables and fruits (aim ~400 g/day for adults).
  • Beans and lentils for extra fiber and protein.

If you tell me your age, weight, height, activity level, and goal (lose, maintain, gain), I can sketch a more tailored daily carb range for you.
