It is a truth universally acknowledged that Katie Hopkins can talk the talk. But if anyone doubted she could actually walk the walk, here's the proof.
The controversial columnist had pledged to put on at least three stone, because she claimed she was tired of fat people making excuses for not being able to lose weight, and she revealed her changed form to Holly and Phillip on 'This Morning'.
Katie has been eating 6,500 calories a day for the last three months, and the result is evident... she has gone from a size eight in dresses to struggling to get into a size 16, and reveals she is "the most miserable she has ever been in her life".
In her column for the Sun at the weekend, Katie revealed that, "I didn’t cry at my weddings. I didn’t cry giving birth. But gaining weight reduced me to a blubbering wreck.
"I hate everything about being fat. I hate the way it feels. My thighs chafe against each other and are sore, my belly sits on top of my thighs and my boobs get in the way."
But, she reveals, this unhappiness has given her a fresh compassion for her overweight peers.
"I now understand my girlfriends in tears before going out, saying they have nothing to wear," she writes. "They mean they don’t feel nice in anything.
"I understand feeling self-conscious about how you look. I can empathise with being fat because I am fat. And it is hard."
Being Katie, she's found time to make it clear that her experiment has proved what she always believed, that "Spoon-feeding a nation excuses when we are so disastrously overweight is not what we need.
"We are the fattest nation in Europe and we need to digest the cold, hard truth that we are like this because we eat too much and move too little.
"My project was to prove that all the excuses for being fat are nonsense — and it is proving that."
Of course, more than a few people will see this as karma for Katie Hopkins' seemingly inexhaustible supply of contempt for the foibles of others, ranging from the tragic fate of Peaches Geldof to those following Ramadan...
