Dr. Siegal's Cookie Diet operates as a relatively focused, family-owned business. While its brand recognition is widespread due to its long history and media exposure, the core company, Dr. Siegal's Direct Nutritionals, LLC, is described as a profitable and debt-free entity.Its operations are centered on the production and distribution of the specific diet cookies, originally formulated by Dr. Sanford Siegal, and now managed with his son, Matthew Siegal, as CEO. The business model initially relied on Dr. Siegal's own medical practice and a network of clinics, but expanded to direct-to-consumer sales via CookieDiet.com and partnerships with major retailers like Walgreens and GNC.Despite its broad reach, the company remains specialized in its niche of hunger-suppressing diet products, maintaining a relatively lean operation focused on its signature cookie formula. It's a "small" company in the sense of being closely held and focused on a particular product line, rather than a sprawling, diversified corporation.
