Simple nutrition and fitness estimators for planning: BMI, calories, protein, macros, and hydration targets.
These tools are for planning and education. They estimate values using common formulas (for example, Mifflin-St Jeor for BMR). Results vary by age, body composition, activity tracking quality, and local clinical guidance.
Not medical advice: ToolFest does not diagnose, treat, or prescribe. If you have a condition, are pregnant, or have dietary restrictions, consult a licensed doctor or registered dietitian before acting on estimates.
