Results include activity level. Weight loss calculations apply a mild calorie reduction.

Educational use only. Medication needs should be reviewed with a healthcare professional.

Estimated macronutrient breakdown

Carbohydrates — g Carbohydrates have the greatest impact on blood glucose.
Protein — g Protein supports muscle maintenance and satiety.
Fat — g Fat provides energy without directly raising blood glucose.

Macronutrient targets are estimates and may require individual adjustment.

Note: Activity level is included in the calorie calculation.

Use the calculator above to estimate daily calorie needs based on your personal details. Accurate inputs for age, body size, and activity level improve the reliability of results. Calorie targets should be interpreted alongside blood sugar patterns and clinical guidance.

How many daily calories does your body need?

Daily calorie needs vary based on age, body size, activity level, and metabolic rate. People with lower activity levels generally require fewer calories to maintain weight, while higher activity increases daily energy needs. For individuals with type 1 or type 2 diabetes, calorie balance can influence blood sugar patterns and medication needs.
