Area of Science:

Metabolic Regulation
Endocrinology
Gastroenterology

Background:

Bile acids (BAs) are recognized as metabolic regulators.
Bariatric surgery shows potential for improving insulin sensitivity via BAs.
The physiological role of BAs in metabolic health requires further elucidation.

Purpose of the Study:

To analyze serum BA composition and gut-derived hormone levels after lifestyle-induced weight loss in metabolic syndrome (MetS).
To investigate the impact of a telemonitoring-supervised weight loss program on metabolic parameters and BA profiles.

Main Methods:

Randomized controlled trial with 74 men (45-55 yr) with MetS.
Intervention: 6-month lifestyle-induced weight loss program via telemonitoring.
Measurements: Serum BA profile, FGF-19, GLP-1, clinical parameters, body composition before and after intervention.

Main Results:

Lifestyle intervention significantly improved insulin sensitivity.
Serum levels of BAs and GLP-1 decreased; FGF-19 remained stable.
Serum BA composition shifted towards an increased 12α-hydroxylated/non-12α-hydroxylated ratio.

Conclusions:

Lifestyle modifications improve metabolic control in individuals with MetS.
Weight loss through lifestyle changes reduces serum BAs and GLP-1.
The study demonstrates a shift in BA composition linked to improved metabolic health.
