How the Estimate Works
- Resting energy uses the adult Mifflin–St Jeor equation.
- Activity multipliers estimate total daily energy expenditure.
- Goal adjustments are intentionally moderate.
- Macronutrients remain within broadly accepted adult distribution ranges.
- Fruit and vegetable guidance uses a minimum 400-gram daily reference.
Important: Individual needs can differ substantially. Consult a registered dietitian or qualified clinician for symptoms, medications, pregnancy, chronic disease, athletic competition, or therapeutic diets.
