It’s not just contestants who get a hard time from the genius brainiacs on Beat the Chasers.
Titans of trivia The Beast and The Sinnerman drive their tailors spare too.
Both Mark Labbett (The Beast) and Paul Sinha (Sinnerman) like to wear Savile Row suits on set.
But their yo-yoing weights as they battle to keep in trim can lead to wardrobe woes behind the scenes.
An insider says professional Savile Row outfitters William Hunt have to be always ready to cut for the Chasers pair as their weights change quickly.
The source said: “It’s not uncommon for brainiacs like The Beast to gain up to a stone in a short space of time, or lose a stone, which makes our jobs difficult.
“We’re constantly doing readjustments or sometimes having to even organise entire new outfits at the last minute.
"And the Chasers aren’t afraid to speak their minds, so sometimes they will throw a bit of a strop about it.
“Things can get fiery.”
Paul Sinha, 51, has been open about his weight struggles.
The stand-up comedian and Parkinson’s sufferer changed his lifestyle to improve his health and lost two stone after a Type 2 diabetes diagnosis in 2018.
He took part in ITV documentary Fast Fix: Diabetes, where he was put on a diet of 800 calories a day.
His Beat The Chasers co-star Mark, 56, has undergone a dramatic body transformation.
He weighed 29st as a teacher and quiz show contestant in the early noughties before finding fame on The Chase in 2009.
But over the past decade he has managed to shed 10st.
