According to oncologist David Gorski "Klaper subscribes to the all-too-common claim that a vegan diet is better than any other and supplements that claim with a belief that undergoing fasts, in which one consumes only water, is a major part of the path to health and wellness". Gorski has claimed that Klaper supports multiple pseudoscience medical claims such as acupuncture and naturopathy, and that Klaper also gives "highly dubious advice for cancer patients, even claiming that fasting can shrink malignant tumors. Klaper claims that fasts will clear up inflammation, eczema, arthritis and other issues." "The situation" according to Gorski, is "way more complicated than Dr. Klaper paints it". As a surgeon himself, Gorski is appalled that Klaper claims that fasting encourages "faster wound healing" a statement that Gorski calls "Bullshit!". Gorski has argued that "the product Dr. Klaper is peddling in terms of science is a massive exaggeration based on dubious science, cherry picked cases, and bad evolutionary analogies. Worse, fasts, even when supervised by a physician, are potentially dangerous".
