A 1937 review in The Philippine Journal of Science described the book as a "startling revelation of the different diet fads and medicinal frauds that are now found in the market... In this book one will find many popular diets in vogue in America, criticized severely and their inconsistencies and dangers clearly presented."

In 1935, Malmberg authored Diet and Die, a book critical of fad diets. The book criticized dietary fads, pseudo-scientific nutrition claims and quack remedies. Malmberg critically examined the ideas of fasting, naturopathy, vegetarianism, low-protein diets, Gayelord Hauser's Eliminative Feeding System, Hay diet, mucusless diet and many others.
