In addition, Marketdata has sponsored seminars exploring the future of the U.S. weight loss market. Mr. LaRosa periodically performs custom research projects and consulting for existing weight loss companies, pharmaceutical companies, advertising agencies, venture capitalists, and entrepreneurs involved in start-ups in the weight loss field.
Marketdata’s diet industry market research has been quoted since 1989 by... The Wall Street Journal, New York Times, Newsweek, USA Today, Forbes, Fortune, Business Week, Entrepreneur, Research Alert, The Bariatrician, Nutrition Business Journal, LA Times, Boston Globe, Chicago Sun Times, as well as dozens of national trade groups, and hundreds of local newspapers nationwide.
Marketdata is the ONLY market research firm to regularly track activities in the U.S. diet/weight loss industry and ALL of its segments: commercial franchises like Weight Watchers and Jenny Craig; medical programs based in hospitals and clinics; diet drugs; diet soft drinks and dinner entrees; diet books and self-improvement cassettes; exercise videos; artificial sweeteners; diet programs offered by health clubs; meal replacement shakes like Slim-Fast; dieter demographics; franchising; "cyberdieting" (web-based diet companies/programs), and more.
Note: Marketdata’s diet industry research is NOT and has never been funded or commissioned by any weight loss company. It is completely unbiased and independently prepared. Marketdata has no financial connections to or interest in any weight loss company.
Marketdata knows the most about this market because we were the first to analyze and define this market in 1989. Marketdata’s research was used as background for 1990 Congressional hearings about the industry’s marketing practices, and it has been quoted extensively in all national periodicals. Mr. LaRosa speaks with journalists and writers every week of the year who seek information on weight loss trends and programs, and Marketdata has more "inside" contacts than anyone. The company is unsurpassed in its ability to obtain hard-to-find information via phone interviews, detailed research, analysis of company press releases and UFOC Franchise documents, etc. Most competitors in this market are private firms, with no annual reports, and, there is no national trade association or magazine covering the industry. In addition, only four publicly owned competitors exist within the industry -- Weight Watchers, Nutri-System, eDiets.com, and Medifast.
