Key result
Vagotomy reduced parasympathetic activity and fat depots in high-fat diet-fed rats (P < 0.05), and corrected fasting hyperinsulinaemia in younger rats only.
Why the study?
Does vagotomy reduce obesity and metabolic syndrome markers in high-fat diet-fed young and adult rats?
Does vagotomy reduce obesity and metabolic syndrome markers in high-fat diet-fed young and adult rats?
p-value: p=< 0.05
Vagotomy reduces parasympathetic activity and fat accumulation in high-fat diet-fed rats, with younger rats showing a greater metabolic response, suggesting the vagus nerve contributes to obesity development.

Preclinical vagotomy findings in obese rats require validation before human application; leaves open age-specific parasympathetic mechanisms in metabolic disease.
Barella et al. (2014) studied Obesity / Metabolic syndrome. Vagotomy vs. Non-vagotomized rats was evaluated on Parasympathetic activity and fat depots (p=< 0.05). Vagotomy reduced parasympathetic activity and fat depots in high-fat diet-fed rats (P < 0.05), and corrected fasting hyperinsulinaemia in younger rats only.
