Leptin (from Greek λεπτός leptos, "thin"), the "satiety hormone", is a hormone made by adipose cells that helps to regulate energy balance by inhibiting hunger.

Leptin is opposed by the actions of the hormone ghrelin, the "hunger hormone".

Both hormones act on receptors in the arcuate nucleus of the hypothalamus to regulate appetite to achieve energy homeostasis.

In obesity, a decreased sensitivity to leptin occurs, resulting in an inability to detect satiety despite high energy stores.

The thyroid gland, or simply the thyroid, is an endocrine gland in the neck, consisting of two lobes connected by an isthmus.

It is found at the front of the neck, below the Adam's apple.

The thyroid gland secretes thyroid hormones, which primarily influence the metabolic rate and protein synthesis.

The hormones also have many other effects including those on development.

The thyroid hormones triiodothyronine (T3) and thyroxine (T4) are created from iodine and tyrosine.

The thyroid also produces the hormone calcitonin, which plays a role in calcium homeostasis.

Metabolism (from metabolē, "change") is the set of life-sustaining chemical transformations within the cells of living organisms.

The three main purposes of metabolism are the conversion of food/fuel to energy to run cellular processes, the conversion of food/fuel to building blocks for proteins, lipids, nucleic acids, and some carbohydrates, and the elimination of nitrogenous wastes.

These enzyme-catalyzed reactions allow organisms to grow and reproduce, maintain their structures, and respond to their environments.

The word metabolism can also refer to the sum of all chemical reactions that occur in living organisms, including digestion and the transport of substances into and between different cells, in which case the set of reactions within the cells is called intermediary metabolism or intermediate metabolism.

A dietary supplement is intended to provide nutrients that may otherwise not be consumed in sufficient quantities.

A vitamin is an organic compound and a vital nutrient that an organism requires in limited amounts.

An organic chemical compound (or related set of compounds) is called a vitamin when the organism cannot synthesize the compound in sufficient quantities, and it must be obtained through the diet; thus, the term vitamin is conditional upon the circumstances and the particular organism.

For example, ascorbic acid (one form of vitamin C) is a vitamin for humans, but not for most other animal organisms.

Supplementation is important for the treatment of certain health problems, but there is little evidence of nutritional benefit when used by otherwise healthy people.
