Overview

• The one‑off film airs Monday, Oct. 6 at 8pm on Channel 4 and channel4.com.
• Joe Wicks partners with Dr Chris van Tulleken, building on van Tulleken’s Ultra Processed People.
• The programme features a satirical ‘KILLER’ protein bar made with legally permitted ingredients that the film says are linked to harms including cancer, diarrhoea, stroke and early death.
• Channel 4 says selling the bar to the public is intended to hold the government to account and push for changes to food laws.
• Promotional materials cite research linking ultra‑processed food to 14% of premature UK deaths, trail a spoof teleshopping advert, and note Wicks expects backlash.
