Reducing IR and NAFLD

This is an abstract from the 2008 AASLD meeting. Rats were fed one of 3 diets for 8 months:

- standard chow (SF) (9% cal for fat)
- high fat (HF) (20% cal from fat)
- HF plus betaine (HF+B) (1.5% betaine in drinking water)

In this high fat diet-induced model of insulin resistance and NAFLD, oral betaine:

- reduced fasting insulin and glucose
- reversed hepatic steatosis
- increased activation of the insulin signaling pathway
- reversed hepatic insulin resistance, as demonstrated by reduced gluconeogenesis and increased glycogen content
