Frequently Asked Questions – Carbohydrate Calculator
General recommendations range from 45-65% of total calories from carbohydrates, or 3-7g per kg of body weight. For a 2000-calorie diet, this equals 225-325g daily. However, needs vary greatly based on activity level, goals, and health conditions. Athletes may need 8-12g/kg, while those managing diabetes might benefit from lower amounts.
Simple carbs are quickly digested and absorbed, causing rapid blood sugar spikes (fruits, dairy, table sugar). Complex carbs take longer to digest, providing sustained energy and better blood sugar control (whole grains, vegetables, legumes). Aim for 70-80% complex carbs and 20-30% simple carbs, with simple carbs mainly from whole food sources.
Timing depends on your goals: For exercise performance, eat 15-30g carbs 30-60 minutes before workouts and 20-50g within 30 minutes after. For weight loss, emphasize carbs earlier in the day and limit them 3 hours before bed. For blood sugar control, pair carbs with protein and fiber, and eat smaller, frequent portions throughout the day.
Exercise significantly increases carb needs. Endurance athletes may need 8-12g/kg body weight, strength trainers need 4-7g/kg, and recreational exercisers need 3-5g/kg. High-intensity and long-duration activities require more carbs for energy and recovery. Sedentary individuals can maintain health with 3-4g/kg of mostly complex carbohydrates.
Carb management is crucial for diabetes, but elimination isn’t necessary. Focus on consistent intake (30-45g per meal for most people), choose low glycemic index foods, pair with protein and fiber, and monitor blood glucose response. Some benefit from lower carb approaches (50-130g/day), while others do well with moderate amounts. Work with healthcare providers to find your optimal range.
