Wellmania is a comedy series that follows a food writer with an unhealthy lifestyle who ends up forced to reevaluate her choices and improve her habits.

The new series is based on the book Wellmania: Misadventures in the Search for Wellness by Brigid Delaney, who is also one of the creators of the Netflix comedy, alongside Benjamin Law.

The official plot for Wellmania is: "When food writer and human tornado Liv has a major health crisis, she is forced to rethink her ‘live fast die young’ attitude. After she scores a once-in-a-lifetime job that will catapult her into the American mainstream, a series of unfortunate events in Australia sees her banned from re-entering the States unless she fixes her health. 

"Throwing herself body-first into a wellness journey, she tries everything from the benign to the bizarre in an attempt to get well quickly and reclaim her old life."

Comedian Celeste Barber leads the cast as Liv, and there's a great line-up of talent who play her nearest and dearest who are around her as she takes on the fitness challenge.
