Changes in bioelectrical and non-bioelectrical variables associated with overweight after a weight-loss program based...

Area of Science:

• Human Physiology
• Microbiology
• Nutritional Science

Background:

• Overweight and obesity are significant health concerns associated with various physiological dysregulations.
• Bioelectrical impedance analysis (BIA) is a non-invasive method to assess body composition and fluid status.
• Intestinal microbiota plays a crucial role in host metabolism and overall health.

Purpose of the Study:

• To evaluate the impact of a 6-day microbiota-focused weight-loss intervention on clinical and BIA variables in overweight women.
• To assess if changes in bioelectrical impedance analysis (BIA) parameters reflect underlying physiological shifts.
• To explore the relationship between intestinal microbiota modulation and improvements in overweight individuals.

Main Methods:

• A 6-day intervention combining a liquid diet, probiotics, psyllium, bentonite, and trans-anal irrigation was administered.
• 12 overweight women were divided into control and experimental groups; 8 lean women served as a reference group.
• 42 clinical and BIA variables were measured at baseline and over 10 weeks, including gut microbiota composition (Firmicutes/Bacteroidota ratio, Akkermansia muciniphila).

Main Results:

• All 42 measured variables showed favorable changes, moving towards those of the lean reference group.
• 32 of these changes were statistically significant, indicating a robust response to the intervention.
• Improvements were observed in both non-BIA clinical variables and BIA-derived parameters.

Conclusions:

• A multimodal, microbiota-oriented protocol led to consistent and clinically meaningful improvements in overweight young women.
• The observed changes in BIA parameters appear to correlate with physiological alterations.
• Further research with larger sample sizes and longer durations is recommended to validate these promising findings.
