US residents in 1992 spent an estimated $30 billion a year on all types of diet programs and products, including diet foods and drinks.
Between $33 billion and $55 billion is spent annually on weight loss products and services, including medical procedures and pharmaceuticals, with weight loss centers garnering between 6 percent and 12 percent of total annual expenditure.
