Out in the Hunter Valley region of New South Wales, Australia, there's a pretty flashy health retreat that even sees visits from overweight or under-healthy Australian celebrities. The Golden Door Health Retreat Elysia can be a healthy spa stay or a gruelling, super-healthy week-long home. You choose whether you simply check in, enjoy whichever aspects of the program you want (and this option includes sugar-free desserts with dinner) or if you sign up for the boot camp version with compulsory activities and (worst of all, we think) no dessert.
