Beyond Diet and Exercise: The Link Between Environmental Obesogens and Weight Gain



The global obesity epidemic is a complex issue with many contributing factors. While diet and exercise are undeniably important, a growing body of research suggests there might be more to the story. Enter environmental obesogens, a class of chemicals that may be tipping the scales towards weight gain.


What are Obesogens?

Obesogens are chemicals we encounter in our daily lives that can disrupt our body's natural metabolic processes. This disruption can lead to:

  • Increased fat storage

  • Disrupted appetite regulation

  • Altered gut microbiome

  • Impaired insulin sensitivity


Forever Chemicals

Environmental obesogens are called "forever chemicals" because of two key characteristics:

Extremely Stable: Their chemical structure makes them highly resistant to breakdown. This means they persist in the environment for a very long time, potentially decades or even centuries. They don't readily degrade naturally.

Bioaccumulation:  These chemicals can accumulate in our bodies, typically in our fat cells, and the environment over time. They can be absorbed through various ways like food, water, dust, or even skin contact. Since they don't break down easily, they can build up in our tissues and the environment, posing long-term health risks.


How Obesogens Work


These chemicals can wreak havoc on our hormones, particularly those involved in fat storage and metabolism. For example, some obesogens can mimic estrogen, a hormone that can promote fat cell development. Others can interfere with leptin and insulin, hormones that signal satiety and regulate blood sugar, respectively.


Early Life Exposure Matters

Research suggests that exposure to obesogens during critical developmental windows, such as pregnancy and infancy, can have lasting effects. This early programming can increase susceptibility to obesity later in life.


Common Obesogens and Where We Find Them

  • Bisphenol A (BPA): Found in plastics, linings of canned goods, and some receipts.

  • Phthalates: Used in personal care products, building materials, and food packaging.

  • Organochlorines: Persistent environmental pollutants found in some foods and water sources.

  • Certain pharmaceuticals: Some medications may have obesogenic effects.



What Can We Do?

While eliminating all obesogen exposure might not be practical, there are steps you can take to reduce your risk:

Minimize BPA: Choose BPA-free containers and opt for fresh or frozen foods over canned.

Read labels: Look for phthalate-free personal care products and avoid unnecessary plastics


Eat organic: Opt for organic produce whenever possible to minimize pesticide exposure.

Support research: Advocate for further research on obesogens and their impact on health.


The Bottom Line

Understanding the role of obesogens in obesity is crucial. By acknowledging these environmental contributors, we can move towards a more comprehensive approach to weight management and public health. Remember, a healthy lifestyle is still essential, but being aware of obesogens empowers you to make informed choices to protect your well-being.


Functional Medicine Has The Answers


Functional medicine takes a different approach to weight management than just counting calories. Here's how:

  • Beyond Calories: It looks for underlying issues like hormones, gut health, or nutrient deficiencies that make it harder to burn calories.

  • Personalized Carbs: Instead of just restricting carbs, it considers your individual insulin response and tailors a diet to keep blood sugar stable.

  • Obesogens: It identifies chemicals that disrupt metabolism and helps minimize exposure to them.

  • Mitochondrial Health: It assesses the function of your cellular powerhouses (mitochondria) and recommends ways to improve them, potentially boosting metabolism.

  • Stress Management: It recognizes chronic stress as a weight gain factor and helps you develop stress management strategies.


By addressing these root causes, functional medicine creates a personalized plan for weight loss and overall health.
