Slimming World is to lose its editor and publisher Christine Michael who has been offered a book deal.
Michael has worked on the diet and fitness title for four years, but now plans to freelance and focus on completing her book.
Her departure follows recent investment which saw the editorial team expand and the frequency increase from six to seven issues a year.
Recent signings include assistant editor Sarah Davison, assistant subeditor Nicola Raphael, art assistant Nicola Duffy and production and design developer Nikki Potts.
Slimming World recorded its highest circulation (267,304) to date in the last ABCs and is in the process of looking for a new editor to oversee the day-to-day running, as well as the ongoing series of public health initiatives.
The title has given its backing to university research projects in nutrition as well as Slimming on Referral – a partnership which offers free slimming to referred patients.
Michael said: “The magazine is in great shape and has loads of potential, as issues surrounding weight, healthy eating and fitness are of such enormous national interest.”
Slimming World launched in 1998 for members of Slimming World – a company founded 35 years ago which runs more than 5,000 weekly slimming groups nationwide.
The magazine expanded its distribution to the news-stand last year.
