Obesity is associated with gut dysbiosis characterized by decreased microbial diversity and an increased Firmicutes/Bacteroidetes ratio, which contributes to obesity through disrupted energy homeostasis, lipid synthesis, and chronic inflammation.
Your gut bacteria play a significant role in how your body handles energy and stores fat. While diet and exercise are crucial, the types of bacteria in your gut can influence your risk of obesity through mechanisms like energy extraction and inflammation. Maintaining gut health through a diverse diet may support metabolic health, but it is not a standalone cure for obesity.
In this review, we have summarized that the microbial diversity was significantly decreased and the Firmicutes/Bacteroidetes ratio was significantly increased in obesity. The altered gut microbiota and associated metabolites contributed to the progression of the disease by disrupting energy homeostasis, promoting lipid synthesis and storage, modulating central appetite and feeding behavior, as well as triggering chronic inflammation

More from this paper
- Altered gut microbiota in obesity increases digestible energy uptake from food through enhanced expression of nutrient transporters and fermentation enzymes, leading to increased caloric absorption.Moderate
- Gut microbiota alterations in obesity contribute to chronic low-grade inflammation through increased lipopolysaccharide (LPS) translocation, which triggers immune responses and insulin resistance.Moderate

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
