How many carbs should I eat per day?

General guidelines: Balanced diet: 45–65% of calories (225–325g at 2,000 cal). Low-carb: 100–150g/day. Very low-carb/keto: <50g/day, often <20g net carbs. Athletes doing intense training need 6–10g/kg body weight. The Dietary Guidelines for Americans recommend 130g/day as the minimum for brain function.

What is the difference between net carbs and total carbs?

Net carbs = Total carbs − Fiber − Sugar alcohols (with adjustments). Fiber and most sugar alcohols don't significantly raise blood sugar. Total carbs are what's listed on nutrition facts. Keto dieters track net carbs. Diabetics and those managing blood glucose should track both and understand their individual glycemic response.
