One dietitian reads this inbox, and it is me. Corrections are the most useful thing you can send, and they get acted on.
Corrections and disagreements
This is what I most want to hear about. If a number looks wrong, a citation does not support the claim it is attached to, or a guideline has been superseded by something newer, tell me. Sports nutrition moves, and a site whose whole argument is that it shows its work has no business being out of date. Every correction gets checked against the source, and when it holds up the page is fixed and its review date updated. You do not need to be polite about it.
Questions about the equations
If something on the methods page is unclear, or you want to know why one equation was chosen over another, ask. Those questions are genuinely interesting to me and the answers usually end up improving the page for everyone.
What I cannot do by email
I cannot give you individual nutrition advice, and I will not answer a question that amounts to asking for a personal plan. That is not me being precious about it. Doing it properly needs an assessment, your history, and usually your labs, and doing it improperly on the basis of two sentences in an email helps nobody and could genuinely set you back.
If you want individual care, find a registered dietitian licensed in your state through the Academy of Nutrition and Dietetics directory. If a calculator here returned something that worries you — a very low target, or a low energy availability flag — that is a good reason to make that call rather than to push on alone.
Press, permissions and reuse
Happy to talk about sports nutrition generally, and happy for teachers, coaches and clinicians to use these calculators with the people they work with. If you want to reproduce a chunk of the written content somewhere, ask first and I will almost certainly say yes with an attribution line.
Response time
This site is not my day job, so give it a few business days. Corrections jump the queue.
