HBO Max is digging into the life of the late Gwen Shamblin Lara, who founded a wildly popular Christian diet program and later, the Remnant Fellowship Church in Tennessee.

The Way Down: God, Greed and the Cult of Gwen Shamblin,a new five-part series debuting on the streamer this month, follows Shamblin Lara’s rise to fame as an influential religious leader who convinced her followers that God had given her “the key to permanent weight control,” which she reveals in the trailer is “a matter of the heart.”

“After rising to fame with her Weigh Down Workshop, a Christian-based diet program that preached slenderness as next to godliness, Gwen Shamblin Lara founded the Tennessee-based church,” the series' official synopsis reads, perHBO. “Despite a carefully curated image, Lara and the church soon fielded accusations of emotional, psychological, and physical abuse, and exploitation for their alleged cult-like practices.”
