🥗 Calorie / Macro Calculator
Estimate BMR, TDEE, daily calories, and protein/fat/carbohydrate targets from transparent assumptions.
Health estimate note
- Nutrition outputs are planning estimates, not medical advice or eating-disorder treatment guidance.
- Health conditions, medication, pregnancy, minors, and eating-disorder history require professional guidance.
Calorie and macro checks
Validates adult-oriented height, weight, and age ranges, labels the activity multiplier and goal delta, and returns copyable estimate/debug summaries.
Why it is useful
It helps plan nutrition targets for weight maintenance, gain, loss, or training goals with transparent assumptions.
How it works
The browser applies common BMR/TDEE formulas and splits calories into protein, carbohydrate, and fat targets.
Best input
Use current body measurements and an honest activity estimate for a realistic starting point.
Health tip
Track real outcomes over time and adjust gradually rather than treating one estimate as fixed truth.
Privacy note
Inputs are processed locally in your browser.
Important limitation
Nutrition calculators are educational estimates, not medical advice. Health conditions, medication, pregnancy, and eating-disorder history require professional guidance.
Quick answers
Are macro targets exact?
No. They are starting estimates that should be adjusted from real progress.
Which activity level should I pick?
Choose the level that matches your average week, not your best training day.
Common Use Cases
Plan daily nutrition for weight goals
Calculate target calories and macronutrient splits based on activity level and body composition goals.
Adjust macros when changing training or diet
Recalculate protein, carbs, and fat targets when switching workout styles or dietary approaches.
