Set Point Theory: What You Should Know


Weight maintenance and management can be challenging. Obesity affects more than 42% of adults and 18.5 percent of children and adolescents in the United States.

Obesity and overweight may be associated with a number of health risks, including the following:

  • Diabetes mellitus
  • Hypertension
  • A stroke
  • Cardiovascular disease.

Numerous people attempt numerous diet programs in an attempt to lose weight.

According to set point theory, our bodies are hardwired with a predetermined weight baseline. Our weight and the extent to which it varies from that set point may be constrained by this theory.

According to the theory, some of us have higher weight set points than others and our bodies struggle to maintain these ranges.

Is there a fixed point at which the human body weight is regulated?

Recent research body weight is influenced by a variety of factors. Weight is influenced by inherited characteristics, the environment, hormonal, psychological, and genetic factors. Additionally, weight is determined by the amount of energy expended in comparison to the amount consumed in calories.

The set point model is predicated on the concept of a genetically determined weight range that is regulated by biological signals. The body has a regulatory system that maintains a steady-state, or set point, condition.

Your brain’s hypothalamus receives signals from fat cells. At specific times, hormones such as leptin, which regulates hunger, and insulin are released. Additionally, your metabolism is constantly adjusting upward or downward in response to a variety of signals.

According to the set point theory, your weight may fluctuate temporarily but will eventually return to its normal set range. The signaling system aids in weight maintenance.

However, it’s critical to recognize that some scientists believe the set point concept may not be particularly useful for comprehending human body weight.

Is it possible for a set point weight to change?

Are you wondering why our weight continues to climb beyond a few pounds despite the fact that we have a set point?

According to some researchers, one reason may be that the reactive signal system becomes inefficient over time, resulting in the development of leptin and insulin resistance, which causes us to gain weight.

External factors also play a role in weight gain over time. The normal body’s set point gradually adjusts upward, according to set point theory.

When we attempt to lose weight, our bodies slow our metabolism in order to maintain the higher set point weight. This can make weight loss more difficult.

A second theory of weight is known as the “settling point” model. This concept implies that our weight is influenced by a variety of factors. Weight fluctuations over time are influenced by how we navigate our food choices in conjunction with our biological characteristics and energy balance.

In general, evidence suggests that weight is not determined by a single factor but rather by a complex set of internal and external signals — a combination of environmental and biological factors.

Can we adjust the weight of our set point? Yes, in accordance with set point theory.

To reset our set point to a lower level, proponents of set point theory recommend a gradual approach to weight loss goals. A gradual 10% weight loss approach combined with consistent maintenance at each stage can assist the body in adjusting to the new lower set point.

Is surgery capable of altering your set point?

A single study in rodents, Trusted Source has demonstrated promise for maintaining weight loss following weight loss surgery. It is unknown whether this would translate to humans, as lifestyle factors such as diet and exercise influence weight.

In some cases, studies indicate that weight loss surgery is effective at maintaining a permanently lower weight range over the long term.

According to scientists, the success of Trusted Source surgery is contingent on a complex set of behavioral and physiological factors. Weight loss is rapid immediately following surgery due to the extreme calorie restriction.

The body adjusts to the decrease in energy intake (fewer calories) over time by slowing metabolism and adjusting leptin signaling. Additionally, if surgery is not accompanied by an active lifestyle, according to set point theory, weight may eventually shift upward to the pre-surgery set point.

The set point theory and binge eating

We’ve discussed weights above and below a set point, but what about weights below the set point?

According to set point theory, after a period of time, your body will attempt to compensate for decreased calorie intake by sending signals (hunger pangs) and slowing your metabolism in an attempt to restore you to your normal set point.

Someone suffering from an eating disorder may become obsessed with food, hunger, and weight, creating a negative feedback loop. This can also result in a binge eating disorder and a cycle of fad diets.

According to set point theory, your body and brain are engaged in a battle to regain a set point weight. As a result, it is more beneficial to make small weight adjustments rather than strict calorie restrictions combined with high energy expenditure from exercise.

Consult your healthcare provider if you have any questions or concerns about disordered eating.

The Takeaway

There is still a great deal we do not understand about how and why our weight changes. Scientists believe that it is critical to understand individual factors. All three factors contribute. Genetics, hormones, and the environment all play a role.

The set point theory is just one concept that researchers are examining in order to gain a better understanding of body weight. There are numerous reasons why some of us struggle with weight loss.

Weight loss programs that are effective must strike a balance between the importance of individual genetic markers and other factors.

Eating a balanced diet and leading an active lifestyle have been shown to aid in weight management.

Do not be discouraged if you have struggled to maintain your weight. It is not a dial that can be adjusted up or down to the desired level.

If you’re interested in losing weight, your healthcare provider can assist you in developing a plan that’s right for you. Additionally, there are blogs and apps that utilize cognitive behavioral models to assist with weight loss.

Suggestions for weight management:

  • Ask experts and your healthcare provider questions
  • Proceed slowly.
  • Experiencing various strategies
  • Positivity
  • To set attainable objectives
