Frequently Asked Questions
How is my daily calorie need calculated?
The calculator uses the Mifflin-St Jeor equation for basal metabolic rate, then multiplies by an activity factor to estimate total daily energy expenditure, and finally applies your weight goal to reach a daily calorie target.
Can I customize the macro split?
Yes. Choose a preset split or adjust the carb, protein and fat sliders directly; the other two adjust so the split always totals 100 percent.
Does this tool store my data?
No. All calculations run entirely in your browser and nothing you enter is uploaded or stored.
