I think my body has several set points. I think they are 170 pounds, 240 pounds, 270 pounds and 310 pounds. These are the weights my body always seem to go to naturally when in that range and it resists other weight points. It is very difficult to get my body lower than these set points. It can take me several months to move past one of these set points. But once I do move past them the weight comes off quicker.
Set point theory states that our bodies have a preset weight baseline hardwired into our DNA. According to this theory, our weight and how much it changes from that set point might be limited. The theory says some of us have higher weight set points than others and our bodies fight to stay within these ranges.
Your hypothalamus, which is in your brain, gets signals from fat cells. Hormones like leptin, which regulates hunger, and insulin are triggered at certain times. Your metabolism also constantly adjusts up or down based on a variety of signals.
The set point theory suggests that your weight may go up or down temporarily but will ultimately return to its normal set range. The signaling system helps maintain weight.
Gradually, according to set point theory, the normal body set point keeps adjusting upward.
When we try to lose weight, our body fights to maintain the higher set point weight by slowing down metabolism. This can limit weight loss.
According to set point theory, after a time, your body will fight reduced calorie intake by sending signals (hunger pangs) and slowing down your metabolism to attempt to bring you back to your normal set point.
Can we change our set point weight? According to set point theory, yes.
In order to reset our set point to a lower level, set point theory proponents recommend going slowly with weight loss goals. A gradual 10 percent step-down weight loss approach with persistent maintenance at each stage can help prepare the body to accept the new lower set point.
Set point theory believes your body and brain are in a struggle to regain a set point weight. Based on this, it’s more helpful to implement smaller adjustments to weight rather than strict calorie restrictions with large energy burns from exercise.
