Does the Microbiome Affect Obesity? Improve Gut Health and Lose Weight with a Long Island Registered Dietitian Nutritionist (RDN)
In my blogs over the past several months, I discussed how a healthy microbiome affects gut health and influences numerous aspects of health such as digestion, immunity, metabolism, and even brain function. Research shows that the microbiome also plays a critical role in the onset and progression of obesity and obesity-related diseases.
How does the microbiome affect obesity?
Dysbiosis, or an imbalance in the gut microbiota, can disrupt normal body functions and lead to health problems—including difficulty managing weight. On the other hand, a healthy, diverse microbiome can actually help you lose weight. By supporting digestion, nutrient absorption, and appetite regulation, healthy microbiomes are critical for sustainable weight management.
The microbiome affects body weight through multiple ways:
- Energy extraction and absorption
- Appetite and satiety signaling
- Inflammation
- Metabolic regulation
- Gut-brain axis communication
Our growing understanding of the gut microbiota opens new possibilities for revolutionary advancements in weight management and overall well-being.
What causes dysbiosis?
Dysbiosis refers to a disruption in the balance between beneficial and harmful bacteria in the gut. It can be caused by a combination of dietary, medical, and environmental factors:
1. Diet
- Low-fiber diets: Starve beneficial gut bacteria
- High-sugar, high-fat diets: Feed harmful bacteria
- Processed foods: Promote microbial imbalance
- Food additives: May negatively impact gut health
2. Medications
- Antibiotics: Kill both good and bad bacteria
- Antacids and other medications: Can alter microbiome composition
3. Environmental and Lifestyle Factors
- Infections
- Inflammation
- Genetics
- Diet
- Antibiotic drug use
