Carbohydrate Needs by Goal
Endurance athletes need 6–10g carbs/kg/day. Strength athletes need 4–7g/kg/day. Moderate exercisers: 3–5g/kg/day. Sedentary individuals: 2–3g/kg/day. Very low carb diets (<50g/day) induce ketosis. Choose complex carbs (oats, rice, vegetables) over refined sugars for sustained energy.
What is the Carbohydrate Calculator?
The Carbohydrate Calculator is a dietary planning tool that helps you determine exactly how many grams of carbs you should eat every day based on your body weight, activity level, and fitness goals. Whether you are trying to lose fat, maintain weight, or build muscle, balancing your carb intake is crucial for energy.
How It Works (Formula)
Carbohydrates provide 4 calories per gram. The calculator first determines your total daily energy needs and then allocates a safe percentage of those calories to carbs based on USDA dietary guidelines or popular diet ratios (like Keto or High-Carb).
$$ \text{Carb Grams} = \frac{\text{Total Calories} \times \text{Carb Percentage}}{4} $$
Divide your carb-allocated calories by 4 to get your daily gram target.
How to Use It
Simply enter your physical stats (age, weight, height) and choose your activity level. Select your primary goal (e.g., weight loss or weight gain), and the calculator will output your recommended daily carbohydrate intake in grams.
