TV tonight: a jaw-dropping film about Trump's female fans

Unreported World
7.30pm, Channel 4

Why do so many women support Donald Trump? This eye-opening, jaw-dropping film sees Karishma Vyas visiting California in search of answers. What she finds is both pitiful and terrifying. Paranoia reigns supreme (“If we meet like this next year, we may be arrested”). Racism and homophobia are as natural as breathing. And Straight Pride events and movements such as TradWives barely conceal a loss of purpose and agency as time overwhelms the antiquated attitudes on display. Watch-through-your-fingers fascinating.

The Truth About Fat
7.20pm, PBS America

“Fat is a feat of evolution,” says one boffin in this myth-busting doc. Sumo wrestlers, hunter-gatherers and supermodels are all studied in order to draw surprising conclusions about fat as a sophisticated, dynamic organ of the human body, which we can’t necessarily control. Jack Seale

Travel Man’s Greatest Trip: Arts and Crafts
8pm, Channel 4

With Joe Lycett primed to take over as Travel Man and planes largely off-limits, what better time to celebrate Richard Ayoade’s minibreaks? This penultimate episode sees Lycett himself visit Amsterdam, while Katherine Ryan is Ayoade’s companion at a minuscule museum in New York. Hannah J Davies

Diana: A Mother’s Love
8pm, Channel 5

Channel 5’s Princess Diana week continues, this time with an investigation into her parenting strategies. She was clearly and understandably desperate to shield her sons from the stifling attention – and overbearing tradition – that comes with royal life. But was she able to prepare them for what lay ahead? PH

Jack Whitehall’s Sporting Nation
8.30pm, BBC One

The last episode in this series celebrates British sporting failure. Oh, where to begin? Perhaps with Archie Gemmill scoring Scotland’s greatest ever World Cup goal, in vain? Or with Derek Redmond’s untimely hamstring twang? Or even with Eddie “The Eagle” Edwards? Heroes, one and all. PH

Code 37: Sex Crimes
9pm, More4

A DJ is brutally raped after a set. That means Detective Hannah Maes (Veerle Baetens) and her team of sexist-but-slowly-learning male colleagues must spend an uncomfortable amount of time on Ghent’s techno scene. Perhaps an NYC field trip and a Flemish-language Law & Order: SVU crossover is now in order? Ellen E Jones

Film choice

American Gangster 10.45pm, ITV Ridley Scott’s glossy crime drama tells the true-life story of Frank Lucas, the Harlem hood who made a fortune smuggling heroin from Vietnam in the coffins of US soldiers.
