Metabolic Analysis

Based on your male, 30-year-old profile with moderate activity level, your TDEE is 2556 calories. For weight maintenance, you should consume 2556 calories daily with 319g of carbohydrates (50% of calories). This standard carb approach provides balanced energy throughout the day.

🍎 Important Notes

  • • Individual carb tolerance varies - adjust based on energy levels
  • • Monitor blood sugar response to optimize carb choices
  • • Consider timing carbs around workouts for best results
  • • Consult a nutritionist for personalized meal planning
  • • Focus on nutrient-dense, whole food carb sources

How it works

A carb calculator sets a daily carbohydrate target from your calorie needs and the share of calories you want from carbs. Since each gram of carbohydrate provides 4 calories, you convert the carb calories to grams by dividing by 4.

Daily carbs

Carb grams = (total calories × carb%) ÷ 4
total calories
your daily calorie target
carb%
share of calories from carbs (e.g. 50%)
÷ 4
calories per gram of carbohydrate

Worked example

  • 2,000 calories/day
  • 50% from carbs
  1. Carb calories = 2,000 × 0.50 = 1,000
  2. Grams = 1,000 ÷ 4

≈ 250 g of carbs per day.

Good to know

  • Mainstream guidance puts carbs at ~45–65% of calories; low-carb and keto diets go much lower.
  • Prioritize fiber-rich whole-food carbs over refined sugar for steadier energy.
  • Carbs, protein, and fat all need to fit the same calorie budget, so raising one lowers the others.
