Are Endocrine Disrupting Chemicals and Your Gut Biome the Reasons Why You are Fat?




About  35 percent of American adults battle with obesity.

When we think of getting fat, most of us blame the conventional calories in/calories out theory.

If you have tried to lose weight by manipulating  the above equation but have failed,  you might want to consider two other factors:

  1. Your gut biome
  2. Endocrine Disrupting Chemicals (AKA- EDCs or Obesogens)



Your Gut Biome

Your gut flora is affected by your environment, diet and lifestyle choices. If your microbiome is thrown out of balance, dysbiosis results, which can result in a number of illnesses or conditions, with obesity being one of them.

Some Common Causes of Dysbiosis

Refined carbohydrates Genetically engineered (GE) foods Agricultural chemicals, such as herbicides and pesticides. Glyphosate
Conventionally raised meats and other animal products Gluten Drugs such asAntibiotics

Proton pump inhibitors(Acid blockers)


Chlorinated and/or fluoridated water Stress Pollution


Lean microbes

Scientists took gut microbes from 4 sets of human twins in which one was lean and the other obese, and then introduced the microbes of each twin into different groups of mice and observed weight and metabolic changes in the mouse groups when fed the same diet.

Mice populated with microbes from a lean twin stayed slim, whereas those given microbes from an obese twin quickly gained weight.

The “lean” and “obese” microbes had different measurable effects on the body’s metabolism.

The researchers were curious about the impact that a typical American diet would have on these obesity-fighting microbes, so repeated the experiment feeding the mice a diet high in saturated fats and low in fruits and vegetables.

On the high-fat diet, the lean mice’s bacteria weren’t able to colonize in the obese mice, and the mice developed obesity.

These results show that expanding gut microbe diversity can help improve health and weight loss when done in conjunction with a balanced diet.  i.e. eating a healthy diet encourages microbes associated with leanness to become incorporated into the gut microbiome.



Endocrine Disrupting Chemicals (AKA- Obesogens)

There is growing interest in the possible health threat posed by endocrine-disrupting chemicals (EDCs). EDCs are substances in our environment, food, and consumer products that interfere with hormone biosynthesis, metabolism, or action, resulting in a deviation from normal homeostasis and reproduction.

Endocrine disruptors have effects on reproduction, cancer, neuroendocrinology, thyroid, metabolism, obesity, and the cardiovascular system.

Numerous studies implicate EDCs as a significant concern to public health due to their effect on estrogenic, androgenic,and thyroid hormones as well as  stress hormones and  neurotransmitters.

EDCs represent a broad class of molecules such as organochlorinated pesticides and industrial chemicals, plastics and plasticizers, fuels, and many other chemicals that are present in the environment or are in widespread use.

How many EDCs  are you exposed to every day?
