Judge Gary Barlow, 40, was already making sure his acts were fit for the competition by hiring a nutritionist to help Craig Colton shed the pounds.
And now Tulisa Contostavlos, 23, Kelly Rowland, 30, and Louis Walsh, 59, have decided that they want to make sure their acts also stay healthy by getting bosses to hire professional chef Andy Goodyear.
Goodyear will cook the meals at the X Factor house and he told British newspaper the Daily Star: 'They are going to get proper, good food.'
A source added: 'The show is a lot of pressure anyway, so it's good that this is one thing they don't have to worry about.'
