Liver FatFOSNCT05962190
Short-term Fat Overfeeding on the Effects of Liver Metabolism
A study testing Diet in people with Liver Fat and Cardiac Function, run by University of Oxford at 1 site in United Kingdom.
Trial summary
Despite work showing the overconsumption of saturated fatty acids (SFA) to be metabolically deleterious, debate continues about whether there is a link between SFA and cardiovascular disease risk. Read more about this study

About this study
Official title: The Effect of Short-term Overconsumption of Specific Dietary Nutrients on Liver and Adipose Tissue Metabolism.
Despite work showing the overconsumption of saturated fatty acids (SFA) to be metabolically deleterious, debate continues about whether there is a link between SFA and cardiovascular disease risk. To explore this, we are undertaking a human in vivo parallel-design study, comparing two isocaloric high-fat diets; one enriched with SFA and the other enriched with unsaturated fatty acids (UFAs), to determine the impact of dietary fat composition on postprandial metabolism, liver fat, cardiac fat and cardiac function.
Read the detailed description
The investigators will recruit men and women with no medical condition or relevant drug therapy that affects lipid, glucose or liver metabolism.
Purpose and design:
The investigators are asking the research question: "How does the amount and type of fat consumed, influence liver fat content, cardiac function and postprandial fatty acid and liver fat metabolism when someone is not gaining or losing body weight?"
To address this research question investigators want to undertake detail physiological studies, in a parallel dietary intervention, where individuals will have an MRI/S scans to assess liver fat, cardiac fat and cardiac function, along with a postprandial study day to assess how their metabolic response to a experimental test meal, before and then 28 days after consumption of a eucaloric, high fat intervention diet that will be either enriched in saturated or unsaturated fat.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
DietBehavioural
High fat (~60% of total energy intake) diet enriched with either SFA or UFA
| Study group | Role | What they receive |
|---|---|---|
| High fat, high SFA | Experimental | ~60% of total energy is from fat, of which ~45% is from SFA, ~55% is from PUFA Receives: Behavioral: Diet |
| High fat, high UFA | Experimental | ~60% of total energy is from fat, of which ~25% is from SFA, ~75% from UFA Receives: Behavioral: Diet |
What is being measured
The primary outcome is the main question the study is designed to answer.
Liver fat
Changes in intrahepatic triglyceride, as measured by MRI
Measured: Pre- and after approx 28 days of consuming interventional diet
Secondary outcomes (1)
Postprandial plasma biochemistry
Changes in postprandial plasma triglycerides, glucose, insulin over 6 hours following consumption of a standardized experimental test meal
Measured: Pre- and after approx 28 days of consuming interventional diet
