Mo Gilligan spent 28 days eating only fried chicken — 84 meals — for a Netflix documentary, Big Chicken: A Fast Food Conspiracy, released August 5, 2026. He gained weight fast and became severely depressed. "What turned into a dream quickly became a nightmare," he told interviewers. The film follows Gilligan from South London to the United States to investigate how chicken became the world's most consumed meat — global per-capita consumption has more than quadrupled since 1961 — and what it costs in health, environmental, labor, and cultural terms. Gilligan, a Black British comedian, also set out to challenge a century of racist stereotyping that linked Black identity to fried chicken, tracing how American racists weaponized a dish rooted in Black American cooking through minstrel shows and films like The Birth of a Nation.

1. The Real Costs Don't Show Up in the Price (Amy Fairman, River Action UK; Magaly Licolli, labor activist)

Cheap chicken is cheap because the real costs land on rivers, workers, and animals — not on the price tag.

This chicken's flavor comes from additives, not the bird. Mark Schatzker, a food and flavor writer featured in the documentary, found that modern industrially farmed chicken contains almost no natural flavor: "You're tasting what they put on chicken." A single Popeyes sandwich contains 142 ingredients, mostly additives.

Rivers are paying the environmental bill. UK farms raise around 24 million chickens at any given time in the River Wye catchment alone. About 70% of the Wye's phosphate pollution comes from agriculture, with levels peaking closest to chicken farms. Natural England downgraded the river to "unfavourable – declining" in 2023. In October 2025, River Action UK filed what it called the largest environmental pollution claim ever brought in the UK — over 4,500 claimants — targeting chicken suppliers Avara Foods and Freemans of Newent, plus Welsh Water. Amy Fairman, River Action's head of campaigns, welcomed the documentary: "This documentary connects the dots between the food on our plates and the health of our rivers."

Workers are paying too. Human-rights activist Magaly Licolli, documented in the film, found that workers at some US poultry facilities wear diapers because management denies bathroom breaks on the production line.

2. But British Farmers Say They're Being Lumped In (Will Raw, NFU Poultry Board Chair)

Britain's chicken farmers meet high standards — and the documentary doesn't make that distinction.

Not all chicken is the same. Will Raw, the NFU's Poultry Board Chair, argues that Britain's farmers produce chicken to some of the highest animal welfare and environmental standards in the world. Raw says treating British farms the same as US industrial operations misrepresents the UK industry entirely.

Wye farmers have a stake in the river too. Raw has been direct: "British chicken farmers who live and work throughout the Wye catchment embrace its beauty every single day" and have voluntarily invested in infrastructure to prevent nutrient runoff.

Restricting UK farming without cutting imports just shifts the harm abroad. Raw argues that raising UK standards further without addressing cheap imports simply moves environmental harm to countries with weaker protections. The NFU is reviewing the documentary and says it will take any steps necessary to ensure reporting remains accurate, fair, and compliant with relevant regulations.

3. The Film Has Its Own Credibility Problem, Though (Benji Wilson, The Telegraph)

The stunt-eating format doesn't prove what it claims — and Gilligan backed down when the evidence might've been real.

Eating 5,000 calories a day makes anyone sick. Benji Wilson, reviewing for The Telegraph, notes the 28-day health decline was "entirely predictable" and covered "well-trodden ground." The experiment proves extreme eating is bad, not that chicken specifically is the culprit.

Super Size Me already collapsed this genre's credibility. Wilson draws the comparison to Morgan Spurlock's 2004 film. Spurlock never disclosed his heavy drinking during filming — his liver damage may have been alcohol-related, not McDonald's-related — and he never released daily food logs. Wilson calls Super Size Me "the once-celebrated documentary whose credibility has largely collapsed in the years since its release."

Gilligan backed out at the critical moment. When animal rights activists invited him into a Lincolnshire chicken farm for undercover footage, Gilligan declined, telling them: "My girlfriend wouldn't let me come with you." Wilson calls this the documentary's failure — Gilligan "chickens out" at precisely the moment new evidence might have landed.

Where This Lands

This fight isn't with the chicken industry — it's over what counts as honest filmmaking. River Action UK has legal claims and river data that stand independently of any 28-day eating stunt. Will Raw and the NFU are right that British farms don't map onto US industrial operations, but the Wye's "unfavourable – declining" rating suggests something has gone wrong locally regardless. Benji Wilson's genre critique has real teeth — the stunt-eating format borrows from a documentarian who hid a key variable. Gilligan does one thing Super Size Me never tried: tracing how American racists turned a dish rooted in Black American freedom into a caricature, then franchised it back as the cheapest food on the block. That part of the argument isn't a stunt, and it doesn't need a 28-day diet to land.
