Alejandro Junger

Alejandro Junger is a Uruguayan-born American cardiologist and functional-medicine physician, best known as the creator of the Clean programme of dietary detox. His book Clean 7 outlines a week-long protocol combining diet, fasting, sleep, supplements and stress reduction to reset the body's energy, immunity and digestion.

Trained in cardiology at Lenox Hill Hospital in New York, Junger practised at the levels of heart disease and chronic illness before founding the popular Clean programme that has guided millions. His approach — treating the gut, the brain and inflammation together — helped bring functional wellness practices into mainstream medicine.
