Secret Eaters presenter Anna Richardson has revealed that she had her own encounter with the scales.
The 42-year-old, who has also hosted You Are What You Eat, experienced a wake-up call while filming a series of Supersize Vs Superskinny.
"I was filmed doing all these diets and I had to get on some scales for the first time in seven years. I had my own Secret Eaters moment where I was faced with the fact I was a damn sight heavier than I thought I was," she said.
Anna and her no-nonsense team are back to uncover the furtive foodies in a second series of Secret Eaters, which films overweight eaters.
"The only reason anyone's overweight is because they take in too many calories, end of story," she explained.
"What I find fascinating is the level of their self-delusion, and I've been there myself because I'm a dieter, and I've struggled with my weight and thought, 'It's not my fault'."
While Secret Eaters "is a sort of comedy-spy-diet show", the aim isn't to humiliate anyone.
"No one wants to laugh at overweight people because it's a huge issue, it's an epidemic in this country," Anna said. "I've been overweight myself and still struggle with my weight, so I hope the tone is absolutely bang on, which is 'Listen - I'm not a skinny person looking at you and thinking you're just a fat slob'."
She added: "I'm looking at them going, 'I've been there, I understand this is difficult. We are here to affect change for you. We're on your side'."
:: The second series of Secret Eaters begins on Channel 4 on March 28.
