Obesity continues to be a global health crisis, increased by an overabundance of food and the body’s natural sensitivity to energy deficits. Bariatric surgery, such as the Roux-en-Y gastric bypass, offers long-term weight loss, but its mechanisms remain unclear. Likewise, vagus nerve stimulation has been explored as a potential treatment for obesity, but it has shown varied results.
During my thesis I focused on three different interventions:
1. Roux-en-Y gastric bypass: Energy intake reduction and weight loss in rats was mainly explained by pre-surgery weight and cumulative energy intake. A high fat diet was associated with less disruption in daily activity and body temperature after surgery. However, we also found that the high fat with added sucrose diet had a major impact on ingestion rate and led to higher glucose levels after a meal.
2. Ileal Transposition: Weight loss was observed, partly due to increased energy expenditure during digestion and a temporary reduction in energy intake.
3. Vagus nerve stimulation: While not leading to weight loss or improvements in glucose regulation in type 2 diabetic rats. It did result in faster glucose processing in healthy rats offering promise for future type 2 diabetes prevention strategies.
