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

Weight loss can either occur unintentionally because of malnourishment or an underlying disease, or 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 increase in exercise is called cachexia and may be a symptom of a serious medical condition.

A dietary supplement is a manufactured product intended to supplement a person's diet by taking a pill, capsule, tablet, powder, or liquid.

A supplement can provide nutrients either extracted from food sources, or that are synthetic (in order to increase the quantity of their consumption).

The classes of nutrient compounds in supplements include vitamins, minerals, fiber, fatty acids, and amino acids.

Dietary supplements can also contain substances that have not been confirmed as being essential to life, and so are not nutrients per se, but are marketed as having a beneficial biological effect, such as plant pigments or polyphenols.

Animals can also be a source of supplement ingredients, such as collagen from chickens or fish for example.

These are also sold individually and in combination, and may be combined with nutrient ingredients.

The European Commission has also established harmonized rules to help insure that food supplements are safe and appropriately labeled.

A systematic review is a scholarly synthesis of the evidence on a clearly presented topic using critical methods to identify, define and assess research on the topic.

A systematic review extracts and interprets data from published studies on the topic, then analyzes, describes, critically appraises and summarizes interpretations into a refined evidence-based conclusion.

For example, a systematic review of randomized controlled trials is a way of summarizing and implementing evidence-based medicine.

In nutrition, biology, and chemistry, fat usually means any ester of fatty acids, or a mixture of such compounds, most commonly those that occur in living beings or in food.
