Natalie, from Crewe, goes to the gym four times a week and has a healthy diet, but is still overweight.

“I would consider myself on the larger side, but I’m fit,” she told the BBC 5 Live phone-in with Nicky Campbell.

“If you look at my BMI I’m obese, but if I speak to my doctor they say that I’m fit, healthy and there’s nothing wrong with me.

“I’m doing everything I can to stay fit and have a long healthy life,” she said.

Richard, from Falmouth, said there is a lot of confusion around BMI.

“When they did my test, it took me to a level of borderline obesity, but my body fat was only 4.9% – the problem is I had a lot of muscle mass,” he says.

In Mike’s opinion, you cannot be fat and fit – he says it is all down to diet.

“All these skinny jabs make me laugh, if you want to lose weight stop eating – it’s easy.”
