Set point theory can be construed as implying weight regulation in a wide or tight range around the set point, in a symmetric or in an asymmetric manner (i.e. treating weight gain and loss either the same or differently), and may apply to regulation of body fat levels specifically (in a multi-compartment model) or to overall body weight. Set ...
Set point (endocrinology), a term encompassing a number of quantities (e.g. body weight, body temperature) where the endocrine system contributes to regulation and homeostasis. Setpoint (control system), the target value that an automatic control system, for example PID controller, will aim to reach; Set point theory, a theory describing how ...
The brain is able to overcome negative feedback in these localized systems and continuously evaluate the body's internal set-points. By doing so, the body can regulate its resources and energy storage efficiently. Another key component of allostasis is the brain's perception and subsequent adaptation to chronic stress.

Once the person's energy levels fall below a certain threshold, the sensation of hunger is experienced, which is the body's way of motivating the person to eat again. The set point assumption is a negative feedback mechanism. [23] Two popular set point theories include the glucostatic set point theory and the lipostatic set point theory.
The formal scientific definition of theory is quite different from the everyday meaning of the word. It refers to a comprehensive explanation of some aspect of nature that is supported by a vast body of evidence. Many scientific theories are so well established that no new evidence is likely to alter them substantially.
This shows that the body cannot precisely compensate for errors in energy/calorie intake, contrary to what the Set-Point Theory hypothesizes, and potentially explaining both weight loss and weight gain such as obesity. This review was conducted on short-term studies, therefore such a mechanism cannot be excluded in the long term, as evidence is ...
In biochemistry, steady state refers to the maintenance of constant internal concentrations of molecules and ions in the cells and organs of living systems. [1] Living organisms remain at a dynamic steady state where their internal composition at both cellular and gross levels are relatively constant, but different from equilibrium concentrations. [1]
