Homeopathy or homoeopathy is a pseudoscientific system of alternative medicine. Its practitioners, called homeopaths, believe that a substance that causes symptoms of a disease in healthy people can cure similar symptoms in sick people; this doctrine is called similia similibus curentur, or "like cures like". All relevant scientific knowledge about physics, chemistry, biochemistry and biology gained since at least the mid-19th century contradicts homeopathy. Homeopathic remedies are typically biochemically inert, and have no effect on any known disease. Its theory of disease, centered around principles Hahnemann termed miasms, is inconsistent with subsequent identification of viruses and bacteria as causes of disease. Clinical trials have been conducted and generally demonstrated no objective effect from homeopathic preparations. The fundamental implausibility of homeopathy as well as a lack of demonstrable effectiveness has led to it being characterized within the scientific and medical communities as quackery and fraud.
A macrobiotic diet is a fad diet based on ideas about types of food drawn from Zen Buddhism. The diet tries to balance the supposed yin and yang elements of food and cookware.

James Tyler Kent (1849–1916) was an American physician best remembered as a forefather of modern homeopathy. In 1897 Kent published a massive guidebook on human physical and mental disease symptoms and their associated pseudoscientific homeopathic preparations entitled Repertory of the Homeopathic Materia Medica, which has been translated into a number of languages. It has been the blueprint to many modern repertories used throughout the world and even remains in use by some homeopathic practitioners today.
A fad diet is a diet that becomes popular for a short time, similar to fads in fashion, without being a standard dietary recommendation, and often making unreasonable claims for fast weight loss or health improvements. There is no single definition of what is a fad diet. The term fad diet encompasses a variety of diets with different approaches and evidence bases, and thus different outcomes, advantages, and disadvantages.

It incorporates primarily the scientific fields of nutrition and dietetics. Furthermore, clinical nutrition aims to maintain a healthy energy balance, while also providing sufficient amounts of nutrients such as protein, vitamins, and minerals to patients.

Gabriel is an American medical doctor, homeopath, and spiritualist and practitioner of holistic medicine. In 1976, Cousens legally changed his name from Kenneth Gabriel Cousens to Gabriel. Cousens advocates live foods therapy, a nutritional regimen which he says can cure diabetes, depression and other chronic degenerative diseases. He is the founder of the "Essene Order of Light", a spiritual organization based upon teachings from the Jewish Kabbalah, the Torah, and modern interpretations of the Essenes. The Essenes are a mystical group from the second century B.C.E. who lived in community, eschewed materialism and grew their own food. The modern Essene movement was founded by Edmond Bordeaux Szekely, a religious scholar who promoted a simple holistic lifestyle of meditation and raw vegan eating and published several books on the Essenes in the early 20th century. Essene Order of Light is taught by Cousens at "Tree of Life Foundation," an organization directed by Cousens and headquartered at its "Tree of Life Rejuvenation Center" in Patagonia, Arizona. Cousens has authored nine books and tours internationally promoting his ideas on food and his spiritual beliefs.

Obesity medicine is a field of medicine dedicated to the comprehensive treatment of patients with obesity. Obesity medicine takes into account the multi-factorial etiology of obesity in which behavior, development, environment, epigenetic, genetic, nutrition, physiology, and psychosocial contributors all play a role. As time progresses, we become more knowledgeable about the complexity of obesity, and we have ascertained that there is a certain skill set and knowledge base that is required to treat this patient population. Clinicians in the field should understand how a myriad of factors contribute to obesity including: gut microbiota diversity, regulation of food intake and energy balance through enteroendocrine and neuroregulation, and adipokine physiology. Obesity medicine physicians should be skilled in identifying factors which have contributed to obesity and know how to employ methods to treat obesity. No two people with obesity are alike, and it is important to approach each patient as an individual to determine which factors contributed to their obesity in order to effectively treat each patient. Physicians specializing in obesity medicine may choose to obtain board certification by the American Board of Obesity Medicine.
