The address for everything — corrections, questions, licensing, or a note that a schedule did not work — is [email protected].
Mail is read once a day on weekdays. Corrections with a source or your own records attached are answered first; general questions may take a few days.
What is useful to include
If you are writing about a specific entry, name it and quote the line you are asking about. Numbers are easier to check than paragraphs.
- The entry title, or the URL.
- The line or figure you think is wrong, and what you think it should be.
- A source if you have one, or the records you kept if you tested the schedule yourself.
- Your body weight and the weather, if the problem was that a plan did not fit you — it changes the arithmetic.
What we cannot do
We cannot give individual medical or dietetic advice, and we cannot tell you how much you personally should drink. That depends on your medication and your kidney and heart function, which we cannot see. Ask your clinician.
We also do not accept sponsored placements inside plans or recipes. If a product appears in an entry, it is because it is the ordinary tool for the job, not because anyone paid for it.
Privacy of your message
Email sent to [email protected] is kept so that corrections can be tracked and, where useful, published. If you would rather your note not be quoted, say so in the first line and it will not be.
