Every message reaches a person, not a ticket queue. Because BMRScope is small, telling us which tool you used and what you expected is the fastest way to a useful reply.

The tool behind this page is BMRScope, a basal metabolic rate calculator. Questions usually involve understanding why two BMR calculators disagree or a number that came out differently than expected, and both are useful to hear about.

Where to write

You can reach us directly at support@bmrscope.com. We aim to reply within one to two business days.

What to include

• Which tool you were using, or the page address.
• The values you put in (your weight, height, age, sex and body-fat percentage), to whatever precision you remember.
• The result you got and the result you expected.
• Your device and browser if something rendered incorrectly.

If your question is about setting a calorie baseline before a diet, say so in the first line — it helps us find the right answer for BMRScope faster.

When a number looks off

Accuracy matters more here than anything else. The method BMRScope uses is stated on the tool's own page — Mifflin-St Jeor weights weight, height, age and sex into a single linear equation, while Katch-McArdle works from lean body mass instead — showing all three makes the disagreement between models visible rather than hiding it — so a result that looks wrong usually means an input sat outside the model's assumptions, or a rounding boundary was hit. Send us the value you expected and the tool you used, and we will verify it against the formula.
