Katie Hopkins has never been one to shy away from sharing her beliefs but after saying that fat people are lazy and have no-one to blame but themselves, she’s decided to put her money where her mouth is by putting on weight just to show how easy it can be to lose it.

The former Apprentice contestant has piled on almost four stone - taking her from 8 stone 8lb to nearly 12 stone - for TLC documentary Katie Hopkins Journey to Fat and Back.

Katie unveiled her fuller figure to ITV’s This Morning hosts Holly Willoughby and Philip Schofield, and admitted her new size had left her “exhausted”.

“It’s really hard to be fat. Carrying this around is exhausting. Feeling my stomach sitting on top of my legs is exhausting,” she revealed.

“Everyone wanted me to put my money where my mouth is. This was that and I used my body to show that we eat too much don’t move enough.

"Britain is eating its way to obesity and struggling to do anything about it. But in the vast majority of cases, the solution is simple.

"Overweight people should eat less and move more and stop blaming everyone else for problems they can control.”

A spokeswoman for the TLC said: "Katie has been very outspoken about her prejudices towards overweight people.

"This documentary will confront her attitudes and put her beliefs to the test by following her own physical and emotional journey as she gains and loses weight, whilst exploring the broader issues of body image in our society."

Katie also revealed that she will start to lose the weight, which she has gained from gorging on chocolate, sweets and takeaways, from September 8.
