Acting deputy editor Rebecca Frank will oversee the health pages, which will cover conventional medicine, emotional health and alternative remedies.
Editor Alison Pylkkanen said: 'Fashion will be included in the mix as and when appropriate.' Health fashion items, such as trainers, will be reviewed along with holiday clothes, such as swimwear, on a seasonal basis, she said.
Zest is redistributing the eight-to-ten fashion pages among beauty, travel and food. The changes will also see an increased emphasis on beauty products.
Pylkkanen added: 'We want to make it more accessible. Readers want to get to the reward quickly. Everyone is interested in health; it's like a new religion, a big part of conversation for women.'
Frank, formerly features editor, is covering deputy editor Linda Bird's maternity leave.
