OMAD is personal. Your health comes first.

OMAD is not right for everyone.

People who are pregnant, under 18, have a history of eating disorders, take glucose-lowering medication, or have medical conditions should speak with a qualified healthcare professional before starting any fasting protocol.

OneMealADay.com is for tracking, education, accountability, and community — not medical advice. Listen to your body, and avoid extremes.
