      Max Wishnofsky asked in a 1958 report, “What is the caloric equivalent of one pound of body weight gained or lost?”
      • Wishnofsky M.
      Caloric equivalents of gained or lost weight.
      Am J Clin Nutr. 1958; 6: 542-546
      After a thoughtful analysis of the existing literature, Wishnofsky concluded that “the caloric equivalent of one pound of body weight lost” or “gained will be 3,500.” Fifty years later and with thousands of citations in the scientific literature and the lay press, Hill and his colleagues repeated the often-used statement “an energy deficit of approximately 3,500 kcal is needed to lose 1 lb of body weight” in the authoritative textbook, Modern Nutrition in Health and Disease.

      Hill and colleagues are not alone, with the same rule of thumb posted more recently on the Mayo Clinic,

      and countless other websites. But Wishnofsky's Rule as applied is inaccurate, leaving many counseled patients wondering why their prescribed weight loss is far less than expected, even when they rigorously adhere to their registered dietitian nutritionist's recommendations.
