Regulation
The regulation of appetite (the appestat) has been the subject of much research in the last decade. Breakthroughs included the discovery, in 1994, of leptin, a hormone that appeared to provide negative feedback. Leptin is a peptide hormone that affects homeostasis and immune responses. Lowering food intake can lower leptin levels in the body, while increasing the intake of food can raise leptin levels. Later studies showed that appetite regulation is an immensely complex process involving the gastrointestinal tract, many hormones, and both the central and autonomic nervous systems.

Famous quotes containing the word regulation:
“Lots of white people think black people are stupid. They are stupid themselves for thinking so, but regulation will not make them smarter.”
—Stephen Carter (b. 1954)
“Nothing changes my twenty-six years in the military. I continue to love it and everything it stands for and everything I was able to accomplish in it. To put up a wall against the military because of one regulation would be doing the same thing that the regulation does in terms of negating people.”
—Margarethe Cammermeyer (b. 1942)
“Nothing can be more real, or concern us more, than our own sentiments of pleasure and uneasiness; and if these be favourable to virtue and unfavourable to vice, no more can be requisite to the regulation of our conduct and behavior.”
—David Hume (1711–1776)
