Breatharianism and Extreme Fasting

Breatharianism is the most dangerous fringe diet, claiming humans can live on sunlight and air alone. Multiple deaths have been directly attributed to breatharianism—at least 4 documented fatalities—yet charismatic leaders like Jasmuheen continue to promote it. Even the most extreme fasting protocols on this list, such as the Lion Diet (rank #10), acknowledge that some caloric intake is necessary; breatharianism rejects even that small concession. This is not a diet trend—it is a documented cause of death, with post-mortem reports consistently showing starvation as the primary cause.
