Xand van Tulleken and Helen Lawal oversee proceedings as three more pairs road test some of the most popular and talked about diets. Drag queens Jordan and Thomas have one week to drop a dress size ahead of their next performance, best friends Earl and Vince go on six-week faith-based diets to slim down before a forthcoming church celebration, and mums Maria and Jules want to lose weight for a kayaking trip in three months. Xand also investigates whether infrared can make people lighter and if it is possible to offset snacks by exercising at work.
