Worldwide obesity is growing exponentially. In 2016, 650 million people were classified as obese. However, not only do we now know what causes obesity, but we also know what to do to prevent it.
The Homeostatic Theory Of Obesity
The new theory of obesity is known as The Homeostatic Theory Of Obesity which has plenty of credible evidence and studies to back it up. It can be explained as follows.
We all have an innate “set weight” which the body tries to maintain by triggering different mechanisms. Consequently, if we consume more calories, then the body triggers mechanisms that decrease hunger and increases energy expenditure and if we consume less calories then the body triggers mechanisms that increase hunger and decrease energy expenditure.
There is a hormone called insulin which regulates metabolism.
Under normal circumstances, high insulin levels encourage the body to store sugar (glycogen) and fat and low insulin levels encourage the body to burn sugar (glycogen) and fat. However, sustained high levels of insulin increases the storage of fat and sugar which increases our “set weight” which ultimately causes obesity and Type 2 Diabetes.
In addition, prolonged cortisol stimulation (for example through stress or sleep deprivation) raises glucose levels and subsequently insulin levels.
In order to create resistance to something, there are two components; high level of something and constant stimulation. Consequently, prolonged levels of high insulin creates insulin resistance which again leads to obesity and Type 2 Diabetes.
How To Lose Weight
- Minimise added sugars.
- Minimise refined grains.
- Moderate protein consumption.
- Increase consumption of natural fats.
- Avoid snacking.
- Increase consumption of fibre which decreases food intake and slows down food absorption.
- Intermittent fasting ― by cycling between low and high levels of insulin, the body never gets a chance to adapt. This is the most efficient strategy to decrease insulin levels.
Summary
The new theory of obesity is known as The Homeostatic Theory Of Obesity. It posits that the body tries to maintain an internal homeostasis (set weight). However, eating and lifestyle behaviours can lead to prolonged high insulin levels which ultimately leads to obesity and Type 2 Daibetes.
By gaining a deep understanding of how obesity develops, we empower ourselves with the knowledge not only on what steps to take to reverse obesity, but also on how to prevent.
