Britain’s Fat Fight
9pm, BBC One
The UK spends more money on treating obesity and diabetes than it spends on the police, the fire service and the judicial system combined. Which suggests that Jamie Oliver’s 2005 challenge to British eating habits was largely in vain. Hugh Fearnley-Whittingstall (above) is having a try now, attacking sneaky marketing strategies, attempting to persuade Newcastle upon Tyne to tighten its belt collectively and learning why obesity is a class issue. Watchable and well-intentioned, even if it feels as if we have all been here before. Phil Harrison
Britain’s Brightest Family
8pm, ITV
The trivia quiz comes to a close, with the Curtis and Collier families hoping to win a trip to Nasa headquarters. Primary-school-level questions aside, the strangest thing about this format has to be the hothousing atmosphere: children taking on adults, both sides administering constant stink eye, is weird. Hannah J Davies
The Assassination of Gianni Versace
9pm, BBC Two
Ryan Murphy’s retelling of the events leading up to the murder of Gianni Versace concludes with all the innate class of a queue of traffic rubbernecking a car crash. As Andrew Cunanan basks in his infamy, glued to the TV screens reporting what he has done, the manhunt closes in. Ben Arnold
Benidorm
9pm, ITV
It is tempting to see it purely as a sort of TV equivalent of sheltered accommodation for light entertainment performers, but Benidorm, which is now 10 series old, clearly continues to find an appreciative audience. Tonight, Monty hunts for a job and Kenneth bricks himself when builders inadvertently brick him in. Jonathan Wright
Me and My Addiction
9pm, Channel 5
The conceit of Me and My … is the simple, effective one of drawing testimony from people with direct experience. Tonight’s focus is drug addiction. It is a shame that the programme feels obliged to stir in celebrity guests, but the point that addiction lurks as a trap in any walk of life is a fair one. Andrew Mueller
Rich Kids Go Skint
9pm, 5Star
Tonight, Sepii, the daughter of an Iranian multimillionaire, goes to live with the Hussains, who are on benefits even though the father works. They are able mentors, but appalled that Sepii is so pampered that she doesn’t brush her own hair. Lessons are learned, but inequality isn’t properly interrogated. David Stubbs
