Initial Weight Loss, Anthropometric Parameters, and Proinflammatory Transcript Levels in Patients with Class I...

Area of Science:

• Obesity research
• Metabolic syndrome
• Genetics and personalized medicine

Background:

• Effective weight loss interventions are crucial for managing obesity.
• Identifying early predictors can optimize therapeutic strategies for weight management.
• The role of the FTO rs9930506 gene variant in weight loss response requires further investigation.

Purpose of the Study:

• To investigate early predictors of successful weight loss in individuals with class I obesity.
• To assess the impact of the FTO rs9930506 gene variant on weight loss outcomes.
• To examine the relationship between changes in inflammatory markers (IL-6, TNF-α, NF-κB) and weight loss effectiveness.

Main Methods:

• 106 subjects with class I obesity participated in a 12-week weight loss program.
• Anthropometric and body composition were measured using bioelectrical impedance analysis (BIA).
• Gene expression of inflammatory markers in white blood cells (WBCs) and adipose tissue (AT) were analyzed.

Main Results:

• The FTO rs9930506 variant did not influence weight loss or reduce proinflammatory markers.
• Initial weight loss after 4 weeks was the strongest predictor of 12-week weight loss success.
• Changes in anthropometric parameters were linked to carbohydrate metabolism, not inflammatory markers.

Conclusions:

• Early weight loss achievement is a key indicator of long-term weight management success.
• The FTO rs9930506 variant does not appear to affect weight loss outcomes in this cohort.
• While WBC gene expression reflects AT changes, inflammatory markers are not associated with weight loss effectiveness.
