Nutrition is the science that interprets the interaction of nutrients and other substances in food in relation to maintenance, growth, reproduction, health and disease of an organism.

It includes food intake, absorption, assimilation, biosynthesis, catabolism and excretion.

Alternative medicine or fringe medicine are practices claimed to have the healing effects of medicine but which are disproven, unproven, or impossible to prove, or are excessively harmful in relation to their effect; and where the scientific consensus is that the therapy does not, or can not, work because the known laws of nature are violated by its basic claims; or where it is considered so much worse than conventional treatment that it would be unethical to offer as treatment.

Alternative therapies or diagnoses are not part of medicine or science-based healthcare systems.

Alternative medicine consists of a wide variety of practices, products, and therapies—ranging from those that are biologically plausible but not well tested, to those with known harmful and toxic effects.

Contrary to popular belief, significant expense is paid to test alternative medicine, including over $2.5 billion spent by the United States government.

Almost none show any effect beyond that of false treatment.

Perceived effects of alternative medicine may be caused by placebo; decreased effect of functional treatment (and therefore potentially decreased side effects); and regression toward the mean where improvement that would have occurred anyway is credited to alternative therapies; or any combination of the above.

Alternative treatments are neither the same as experimental medicine, nor traditional medicine — although the latter, when used today may be considered alternative.

Health is the level of functional and metabolic efficiency of a living organism.

In humans it is the ability of individuals or communities to adapt and self-manage when facing physical, mental or social changes.

The World Health Organization (WHO) defined health in its broader sense in its 1948 constitution as "a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity." This definition has been subject to controversy, in particular as lacking operational value, the ambiguity in developing cohesive health strategies, and because of the problem created by use of the word "complete".

Other definitions have been proposed, among which a recent definition that correlates health and personal satisfaction.

Weight loss, in the context of medicine, health, or physical fitness, refers to a reduction of the total body mass, due to a mean loss of fluid, body fat or adipose tissue and/or lean mass, namely bone mineral deposits, muscle, tendon, and other connective tissue.

Weight loss can either occur unintentionally due to malnourishment or an underlying disease or arise from a conscious effort to improve an actual or perceived overweight or obese state.

"Unexplained" weight loss that is not caused by reduction in calorific intake or exercise is called cachexia and may be a symptom of a serious medical condition.

is commonly referred to as slimming.

Physical exercise is any bodily activity that enhances or maintains physical fitness and overall health and wellness.

It is performed for various reasons, including increasing growth and development, preventing aging, strengthening muscles and the cardiovascular system, honing athletic skills, weight loss or maintenance, and also enjoyment.

Frequent and regular physical exercise boosts the immune system and helps prevent "diseases of affluence" such as cardiovascular disease, type 2 diabetes, and obesity.

It may also help prevent stress and depression, increase quality of sleep and act as a non-pharmaceutical sleep aid to treat diseases such as insomnia, help promote or maintain positive self-esteem, improve mental health, maintain steady digestion and treat constipation and gas, regulate fertility health, and augment an individual's sex appeal or body image, which has been found to be linked with higher levels of self-esteem.

Childhood obesity is a growing global concern, and physical exercise may help decrease some of the effects of childhood and adult obesity.

Some care providers call exercise the "miracle" or "wonder" drug—alluding to the wide variety of benefits that it can provide for many individuals.

Aside from the health advantages, these benefits may include different social rewards for staying active while enjoying the environment of one’s culture.

Many individuals choose to exercise publicly outdoors where they can congregate in groups, socialize, and appreciate life.
