Weight Watchers plans to offer its dietary services in the workplace so that employees can be helped to shed weight and adopt a more healthy lifestyle.

Employees working at firms that take on the Weight Watchers' at work programme will be given advice on healthy eating at classes held during their lunch hour or immediately after they finish work.

Employers that have signed up so far, include Waitrose that provides a Weight Watchers club for employees at its head office in Bracknell.
