What We Can Help With
- Calculator feedback. A result looks wrong, a field behaves oddly on your phone, or you would like a feature added. Tell us your device, browser and the numbers you entered.

What We Cannot Help With
We are a calculator and information site, not a clinic. We cannot give personal medical advice, interpret blood tests, build meal plans for a health condition or tell you whether a diet is safe for you. A doctor or registered dietitian can do that properly. If you are unsure, our disclaimer explains the limits of the calculator.
Quick Answers
- How accurate is the calculator? Estimates like these are usually within about ten percent of real needs. Use the result for two to three weeks, watch your weekly average weight, then adjust.
- Why does my result differ from another calculator? Different formulas, activity multipliers and default deficits. The guide on the home page explains the differences.
- Is my data stored? The numbers you enter stay in your browser. Read the privacy policy for details.
- Can I use your content on my site? Short quotes with a link back are fine. For anything larger, please ask first.
