“I still get it now, just last week someone called me fat, I get it all the time,” she revealed.
“There’s people who say I look like ‘Desperate Dan’ because I’ve got a big jaw and sometimes that really hurts.”
The star’s revelation comes as part of the new BBC health show, which she hosts alongside Hugh Fearnley-Whittingstall, 55.
Steph previously told how she had been left feeling “upset and embarrassed” on the show after an analysis of her faeces highlighted her poor gut health.
