Frequently Asked Questions
How many carbs should I eat per day?
Daily carb intake depends on your diet goals. Standard diets recommend 45-65% of calories from carbs (225-325g for 2000 calories). Low-carb diets use 20-30% (100-150g), while keto diets stay under 10% (20-50g).
What is the difference between total carbs and net carbs?
Net carbs = Total carbs - Fiber. Fiber is not fully digested, so net carbs represent the carbohydrates that affect blood sugar. This is especially important for keto and diabetic diets.
How do I calculate carbs from calories?
Carbohydrates contain 4 calories per gram. To calculate carb grams: (Total Calories x Carb Percentage) / 4. For example, 50% carbs on 2000 calories = (2000 x 0.50) / 4 = 250g carbs.
What is the keto diet carb limit?
The ketogenic diet typically limits carbs to 20-50 grams per day, or less than 10% of total calories. This low carb intake helps your body enter ketosis, burning fat for fuel instead of glucose.
Does activity level affect carb needs?
Yes, more active individuals generally need more carbohydrates for energy. Athletes and those with physical jobs may require higher carb percentages to fuel performance and recovery.
