The Weight Watchers program was founded in 1963 and has been growing and going strong ever since. The main foundation of the program is budgeting and keeping track of food and exercise using a "points" formula. They recently revamped the program and launched a new system called PointsPlus™. Members attend meetings and have regular weigh-ins or they can choose an independent approach using Weight Watchers Online. Prices to join vary by area or the online program costs about $5.00 per week when you join for at least 3 months.
