The former editor of Waitrose Food Magazine recently adopted a plant-based diet for seven days, two years after he joked about killing vegans in a leaked email.

William Sitwell caused controversy after he responded to a pitch from freelance journalist Selene Nelson, who had pitched him a series of vegan recipes, suggesting that instead they run a feature on killing vegans.

Sitwell resigned from his role at the magazine two days later, but the journalist who called him out recently published a book, Yes Ve-gan!, on how to live life as a vegan and challenged him to use it as a guide to try eating like a vegan for a week.

Sitwell agreed and shared his experience in an article featured on The Daily Telegraph, where he revealed that he felt the benefits of the diet after a single week.

Although he admitted he would return to eating animal products, he said he planned to “tread occasionally back on to vegan turf” as his body had welcomed his change in diet.

“I never felt bloated after a meal, I never had indigestion and not a glimmer of acid reflux. Pleasingly, I now feel a little leaner,” he revealed.
