Lose A Stone In 21 Days With Michael Mosley

In the first episode, Michael runs a series of tests to find out just how badly lockdown has affected his volunteers' health, before creating a bespoke diet plan for the 21 days.

It is week two of their very low-calorie diet and the volunteers' tempers are beginning to fray, but Michael gets them doing high-intensity work-outs and yoga.

A look at the links between the brain and comfort eating, and snoring and weight. And a sustainable low-calorie, low-carb, high-protein diet with recipes and tips.
