Lose a Stone in 21 Days with Michael Mosley

(Channel 4, 9pm-10pm)

Given all the fridge-raiding many of us have been doing in recent months, this feels like January programming as we try to burn a few post-lockdown calories. As a nation we’ve consumed far more and exercised less and, as a result, piled on the pounds. Here, doctor Michael Mosley devises a lifestyle intervention that will make us feel good while it overhauls our health, as he puts five volunteers on a very low-calorie diet for three weeks in an attempt to help them get their health back on track. In the first episode Michael runs a series of tests to find out just how badly lockdown has affected his volunteers’ health.
