Body for Life is a 12-week diet and exercise program, and also an annual physique transformation competition. It was created by Bill Phillips, a former competitive bodybuilder and owner of EAS, a manufacturer of nutritional supplements. It has been popularized by a bestselling book of the same name.
The first annual Body for Life competition was held in 1996. (It was then called the "EAS Grand Spokesperson Challenge".) Entrants write about their experience of the program, and send this to EAS along with their 'before' and 'after' swimsuit photos. Prizes vary each year, but in 2005 the first prize was US$1,000,000.
Body for Life makes use of principles that have been widely known in bodybuilding. Its differences are in the way it has been packaged and marketed so as to appeal to consumers and be understood by the public. It supports an extensive ancillary industry of gyms, nutritionists and personal trainers.
