"It is with the hope that a somewhat more cheerful outlook on health and continued life may be stimulated in those less than well that this volume is dedicated to the victim himself."
FINANCIAL CONFLICTS
Hay promoted the regimen both as a popular author and as Medical Director of the proprietary Hay System Inc. His books carried the system to a mass readership (the New York Health via Food, 1929, and the Harrap titles A New Health Era, 1935, Weight Control, 1936, and Some Human Ailments, 1937), while its premium delivery was a paid stay at the 'Sanatorium Hotel Headquarters' he ran from Briarcliff Lodge, a luxury hotel at Briarcliff Manor, New York, named as such on the 1935 title page. The conflict is that the man diagnosing the disease (one universal toxic state) also sold the books and directed the proprietary enterprise that sold the cure. The sources here establish his roles as author and as medical director of the named company; they do not document the full financial structure of the Briarcliff Lodge arrangement (a hotel with its own proprietors and staff), so his interest is characterized narrowly, as the books' author and his position directing the enterprise, without attributing the Lodge's proceeds to him.

NOTES

William Howard Hay (1866-1940) was an American physician who, after roughly sixteen years of largely surgical practice, recast himself as the proprietor of a dietary system. By his own account (Introduction, A New Health Era, 1935) he “broke down” with Bright’s disease, high blood pressure, and a dilated heart, and recovered by adopting the regimen he went on to sell. The system, set out in Health via Food (1929) and the mid-1930s Harrap volumes, held that nearly all disease is one acidotic, self-poisoning state caused by wrong eating, and that the corrective is “food separation”: do not eat concentrated starches and concentrated proteins at the same meal, and weight the diet toward base-forming vegetables, salads, and fruit. He framed the payoff in terms of health, restored vitality, and longer life. Hay carried the doctrine into the medical press, defending intestinal autointoxication against its critics in the most sweeping form (Bested, Logan and Selhub, 2013, record him maintaining that autointoxication was responsible for all human ailments). The publicly_disconfirmed status attaches to that system: the autointoxication and acidosis framework was rejected in the early twentieth century, and modern controlled measurement finds no benefit from food separation over an energy-matched mixed diet.
