Healthy thinking and positive outlook are essential features to ensure overall wellness.

Given the important role of health throughout life, scientific research has, from very early on, been focused on factors that could affect health. The genetic background has been acknowledged to be crucial to an individual's health. For example, heritability estimates for type 2 diabetes mellitus (T2DM) range from 20% to 80%. High estimates for the heritability of obesity have also been proposed (typically >70%). However, the exposure to an obesogenic environment is necessary for the development of T2DM and obesity, suggesting that the genetic background is important, but several other environmental/lifestyle factors may also exert a cumulative effect on human health.

The genetic background is important, but several other environmental/lifestyle factors may also exert a cumulative effect on human health.

Lifestyle choices and the way the individuals conduct their lives have recently received great attention, since these factors are modifiable and, therefore, may be subject to intervention and improvement. Lifestyle factors that may affect health include habits, attitudes, tastes, moral standards, economic level, activities, interests, opinions, and values. It is a constellation of motivations, needs, and wants, influenced by factors such as culture, family, reference groups, and social class. Many unhealthy lifestyle choices, such as poor diet, physical inactivity, tobacco use, excessive alcohol intake, and excessive stress have been associated with the development of many chronic diseases. Therefore, scientific research on the lifestyle factors that may have negative (unhealthy lifestyle) or positive (healthy lifestyle) effects on health has intensified over the last decades.

Even small changes toward healthy lifestyle choices can translate to significant benefits in the prevention and treatment of chronic diseases.

The findings are very encouraging; even small changes toward healthy lifestyle choices can translate to significant benefits in the prevention and treatment of chronic diseases. The clinical significance is so obvious that a few years ago the first professional organizations to promote lifestyle changes as a means to prevent and treat diseases were formed. In 2004 the American College of Lifestyle Medicine (ACLM) was formed to provide education and certification to health professionals who wanted to use lifestyle changes as the foundation of a transformed and sustainable health‐care system. According to the ACLM, “Lifestyle Medicine is the use of a whole‐food, plant‐predominant dietary lifestyle, regular physical activity, restorative sleep, stress management, avoidance of risky substances, and positive social connection as a primary therapeutic modality for treatment and reversal of chronic disease.”

Soon after the ACLM was formed, many similar organizations were formed (e.g., Lifestyle Medicine Global Alliance, European Lifestyle Medicine Council, European Lifestyle Medicine Organization, British Society of Lifestyle Medicine, Australasian Society of Lifestyle Medicine), demonstrating the global realization of the benefits of lifestyle medicine.

Wellness is the holistic integration of an individual's physical, mental, and spiritual health.

The “Six Dimensions of Wellness” are physical, occupational, social, intellectual, spiritual, and emotional wellness.

Healthy thinking and positive outlook are essential features to ensure overall wellness.

Several parameters such as the genetic background and environmental and lifestyle factors affect human health.

Lifestyle choices, as modifiable factors, may have negative (unhealthy lifestyle) and positive (healthy lifestyle) impact on health.
