Clinical Trial Summary

In health,adipose tissue stores fat from the diet. If the fat tissue stops storing dietary fat then this increases the chance of it being stored in the liver, which is related to increased risk of heart disease and type 2 diabetes. It has been suggested that having a diet high in sugars or certain fats, may cause the fat tissue and liver to change how they function; we would like to investigate this in detail.


Description:

This research aims to investigate how the overconsumption of specific macronutrients may effect adipose tissue and liver metabolism and function. Liver and heart fat content and adipose tissue and liver metabolism fasting and postprandial lipid metabolism will be assessed before and after the specific dietary intervention.

Outcome

Type Measure Description Time frame Safety issue
Primary Liver de novo lipogenesis Investigators will utilise stable isotope tracer methodology to measure the change in the contribution of newly synthesised fatty acids to very low density lipoprotein triglyceride Within 21 days after starting the intervention diet
Secondary Adipose tissue metabolism Investigators will measure the change in the expression of key lipogenic genes in subcutaneous adipose tissue Within 21 days after starting the intervention diet
Secondary Liver fat accumulation Investigators will measure the change in the amount of fat within the liver using MRI/S Within 21 days after starting the intervention diet
