How It Works

Daily carbohydrate grams are calculated from your total calorie target and chosen diet type. Carbs provide 4 calories per gram. On a 2,000-calorie Balanced diet (45% carbs): 2,000 × 0.45 ÷ 4 = 225g carbs per day.

Quick Reference

Tips & Shortcuts

Choose complex carbs (oats, sweet potato, legumes) over refined carbs (white bread, sugar) for better blood sugar control and satiety.

Fiber is a carbohydrate that is not digested — it does not raise blood sugar and does not need to be counted for keto.

Carb timing matters for athletes: consume most carbs around training for performance and recovery.

Common Mistakes

Cutting carbs to zero without medical guidance

Very low carb diets can cause fatigue, nutrient deficiencies, and hormonal disruption if not planned carefully. Start with moderate reduction.

Ignoring fiber in carb counts

Fiber supports gut health, satiety, and blood sugar stability. Aim for 25–35g of fiber daily within your carb allowance.

Frequently Asked Questions

Recommended ranges: Ketogenic under 50g/day net carbs; Low-carb 50–100g; Moderate 130–225g; Standard 250–300g. The right amount depends on goals, activity, and metabolic health.

Net carbs = total carbs minus fiber minus sugar alcohols. Fiber and most sugar alcohols do not significantly raise blood sugar.

Excess total calories cause weight gain, not carbohydrates specifically. Refined carbs are easy to overconsume. Whole food carbs provide fiber that supports satiety.
