Hunger, Eating and Health - Body Weight Regulation: Set Points Versus Settling Points - Set Point and Settling Points in Weight Control
3 important questions on Hunger, Eating and Health - Body Weight Regulation: Set Points Versus Settling Points - Set Point and Settling Points in Weight Control
What is the principle of a settling-point model?
Body weight drifts around a settling point - this is the level where body weight influencing factors reach an equilibrium.
When fat levels increase, changes will occur so further increase is limited until a balance is achieved between all factors that encourage weight gain and those that discourage weight gain.
What is the critical difference between the set-point and settling point?
The set-point theory implies that when weight is gained, it will return to the set-point.
The settling-theory implies that when weight is gained, the negative feedback system limits further increase, and it does not necessarily bring weight back down to its original value.
Pinel suggests a leaky barrel method to explain the settling-point mechanism. How does this mechanism work?
If a leaky barrel is compared to our internal system, the system goed like this; the more food enters the barrel, the heavier it gets and the heavier the barrel gets, it will eventually close the hose on which it leans. However, food is also leaked from the barrel, so the barrel get lighter and more food can enter the barrel.
