A fad diet is a diet that is popular, generally only for a short time, similar to fads in fashion, without being a standard scientific dietary recommendation, and often making unreasonable claims for fast weight loss or health improvements; as such it is often considered a type of pseudoscientific diet. Fad diets are usually not supported by clinical research and their health recommendations are not peer-reviewed, thus they often make unsubstantiated statements about health and disease.
A dietitian, medical dietitian, or dietician is an expert in identifying and treating disease-related malnutrition and in conducting medical nutrition therapy, for example designing an enteral tube feeding regimen or mitigating the effects of cancer cachexia. Many dietitians work in hospitals and usually see specific patients where a nutritional assessment and intervention has been requested by a doctor or nurse, for example if a patient has lost their ability to swallow or requires artificial nutrition due to intestinal failure. Dietitians are regulated healthcare professionals licensed to assess, diagnose, and treat such problems. In the United Kingdom, dietitian is a 'protected title', meaning identifying yourself as a dietitian without appropriate education and registration is prohibited by law.
A nutritionist is a person who advises others on matters of food and nutrition and their impacts on health. Some people specialize in particular areas, such as sports nutrition, public health, or animal nutrition, among other disciplines. In many countries, a person can claim to be a nutritionist even without any training, education, or professional license, in contrast to a dietitian, who has a university degree, professional license, and certification for professional practice.

Health psychology is the study of psychological and behavioral processes in health, illness, and healthcare. The discipline is concerned with understanding how psychological, behavioral, and cultural factors contribute to physical health and illness. Psychological factors can affect health directly. For example, chronically occurring environmental stressors affecting the hypothalamic–pituitary–adrenal axis, cumulatively, can harm health. Behavioral factors can also affect a person's health. For example, certain behaviors can, over time, harm or enhance health. Health psychologists take a biopsychosocial approach. In other words, health psychologists understand health to be the product not only of biological processes but also of psychological, behavioral, and social processes.

Nursing in the United Kingdom has a long history. The current form of nursing is often considered as beginning with Florence Nightingale who pioneered modern nursing. Nightingale initiated formal schools of nursing in the United Kingdom in the late 19th and early 20th centuries. The role and perception of nursing has dramatically changed from that of a handmaiden to the doctor to professionals in their own right. There are over 700,000 nurses in the United Kingdom and they work in a variety of settings, such as hospitals, health centres, nursing homes, hospices, communities, and academia, with most working for the National Health Service (NHS). Nurses work across all demographics and requirements of the public: adults, children, mental health, and learning disability. Nurses work in a range of specialties from the broad areas of medicine, surgery, theatres, and investigative sciences such as imaging. Nurses also work in large areas of sub-specialities such as respiratory, diabetes, neurology, infectious diseases, liver, research, cardiac, and stoma. Nurses often work in multi-disciplinary teams but increasingly are found working independently.

Preventive Nutrition is a branch of nutrition science with the goal of preventing, delaying, and/or reducing the impacts of disease and disease-related complications. It is concerned with a high level of personal well-being, disease prevention, and diagnosis of recurring health problems or symptoms of discomfort which are often precursors to health issues. Preventive nutrition may assist in prolonging the onset of non-communicable diseases and may allow adults to experience more "healthy living years" later in life. The need for preventive nutrition continues to grow as the overweight and obese population numbers steadily rise within the childhood to adult populous, as the numbers have increased over the last 40 years. To educate the public about preventive nutrition, each social structure has its own way of communicating what preventive nutrition is within its own society, this is done through either a public health forum, government programs and policies or nutritional education. In the United States, preventive nutrition is taught to the public through the use of the food pyramid or MyPlate initiatives.
