Adipostat

Adipostat

A hypothetical mechanism and set-point region that may reside in the ventromedial, lateral, and paraventricular nuclei of the hypothalamus and possibly elsewhere, which regulates body fat within a narrow range based on intake and energy expenditure. It appears (assuming this simplistic entity actually exists) to maintain the metabolic status quo, and modify behaviours traditionally perceived as voluntary—e.g., eating and physical activity—as well as metabolic activity to compensate for changes in diet.

After finding abnormal levels of a substance called adipsin in overweight rodents, researchers in Boston said last week that adipsin may be a contender for the adipostat title, as well as a marker to differentiate among obesities due to defects in genes, metabolism or just plain will power.
