Your Set Point
When body weight and fat levels fall below your set point, your body activates defense mechanisms to maintain body weight and fat in order to prevent starvation, even in people with obesity.
Everyone’s set point is different and can be changed. It appears that the body regulates fat set points similarly to how it regulates other body functions such as blood glucose, cholesterol, and blood pressure. Set points are affected by genetic, developmental, and environmental factors. Changes in any of these factors can lead us to an elevated set point for body fat storage. For example, changes in chemicals and nutrients contained in our foods can affect our brains in ways that increase the amount of food we eat and increase our body fat set point.
Additionally, as you gain weight, your set point is increased and your body works to defend the higher set point. Your body is smart, and it adapts when new things come its way. But, sometimes it’s not for the better.
