In "Why We Eat (Too Much)" by Dr. Andrew Jenkinson, the set point theory is a central concept for understanding weight regulation and obesity.
The set point theory posits that each person’s body has a predetermined weight range, regulated by the hypothalamus in the brain, that it naturally tries to maintain. This set point acts like a thermostat, adjusting physiological processes to keep weight stable.
The body uses multiple mechanisms to maintain weight around this set point, including hormonal signals, appetite control, energy expenditure, and metabolic rate. When weight deviates from this set point, the body adjusts these mechanisms to bring the weight back to the set point range.
Your set point is influenced by:
Hormones, such as leptin, insulin and ghrelin
Genetics (inherited traits related to metabolism, appetite, and fat storage)
Environment and lifestyle (diet, physical activity, stress levels, and sleep patterns)
You can reset the set point can be achieved by a nutrient-dense diet: Eating whole, unprocessed foods helps regulate hormones and supports metabolic health. Focus on a balanced diet rich in vegetables, fruits, lean proteins, and healthy fats.
Additionally, lowering the intake of refined carbohydrates and sugars can help reduce insulin levels, making it easier for the body to burn fat.

By understanding and addressing these factors, you can work towards lowering your set point, which can lead to sustainable weight loss and better long-term health.
