How to use the Carbohydrate Calculator
Estimate a daily carbohydrate target from energy needs and the selected carbohydrate share. It includes Maintain, Gradual loss, Gradual gain workflows, so choose the one that matches the values you actually know. Use it to understand an educational estimate and the inputs behind it, not as a diagnosis or treatment decision.
Step by step
- For the Carbohydrate, enter weight, height, age, gender, activity. Keep each value in the unit displayed beside its field.
- Review the selected Carbohydrate workflow and inputs, then read carbohydrate target in the result panel.
- Change one Carbohydrate assumption at a time to compare scenarios. Use Reset to restore this tool's worked example values.
How the calculation works
Mifflin–St Jeor or Katch–McArdle BMR, activity expenditure, goal adjustment, and nutrient allocation.
Worked example
In the Carbohydrate worked example, weight 75 kg, height 175 cm, age 35 years, gender Male produces carbohydrate target of 291.9 g/day. Mifflin–St Jeor BMR × activity with maintenance adjustment. Review the displayed units before comparing the result.
Understanding the result
The Carbohydrate reports carbohydrate target. Use it to understand an educational estimate and the inputs behind it, not as a diagnosis or treatment decision. Educational estimate only; it cannot diagnose a condition or replace advice from a qualified health professional.
How to check the answer
Check the Carbohydrate estimate by confirming the units and supported ranges for weight, height, age. Compare carbohydrate target with another published method or direct measurement when available, and ask a clinician before using it for a health decision.
Common questions
What does the Carbohydrate calculate?
Estimate a daily carbohydrate target from energy needs and the selected carbohydrate share.
Which Carbohydrate inputs have the biggest effect?
carbohydrate target responds directly to weight, height, age, gender, activity. Change one input while holding the others constant to see its effect.
Is the Carbohydrate result exact?
Educational estimate only; it cannot diagnose a condition or replace advice from a qualified health professional. Recheck weight, height, age and use carbohydrate target only for a decision where that level of precision is appropriate.
