Ramadan fasting positively impacts gut bacteria, increasing Bacteroides and Firmicutes. This dietary change also improved lipid profiles and reduced BMI, suggesting health benefits.
Area of Science:
- Microbiology
- Human Nutrition
- Metabolic Health
Background:
- Investigating the physiological effects of Ramadan fasting on gut microbiota and metabolic markers.
- Understanding the impact of intermittent fasting on specific gut bacteria and serum metabolites.
Purpose of the Study:
- To examine the influence of Ramadan fasting on gut bacteria (Bacteroides and Firmicutes).
- To assess changes in serum butyrate concentration and lipid profiles during Ramadan.
- To evaluate alterations in body mass index (BMI) and food intake.
Main Methods:
- Studied 30 healthy individuals before and after Ramadan.
- Measured serum butyrate, lipid profile, and fasting blood sugar (FBS).
- Utilized RT-PCR for gut bacteria quantification and food records for dietary assessment.
Main Results:
- Serum butyrate levels significantly increased (0.23 to 0.46 mM).
- Bacteroides and Firmicutes populations rose by 21% and 13%, respectively.
- Significant reductions observed in BMI, LDL, HDL, and total cholesterol.
Conclusions:
- Ramadan fasting promotes beneficial gut bacteria, Bacteroides and Firmicutes.
- These microbial shifts may contribute to improved health outcomes.
- Further research is warranted to confirm these findings.
