Carbs vs fats: which diet is better for your heart? oxford launches new study
NCT ID NCT05973539
First seen May 24, 2026 · Last updated Jun 22, 2026 · Updated 8 times
Summary
This study from the University of Oxford looks at how eating a diet very high in either carbohydrates or fats (65% of calories) changes blood fat levels and liver fat in 60 healthy adults. Participants will follow one of two diets for a short time, and researchers will measure changes in triglycerides and liver fat using blood tests and MRI. The goal is to understand which diet composition may lower the risk of heart disease and diabetes, and whether a person's genes play a role.

Active substance
Diet: eucaloric diet enriched in either carbohydrates or fat (both contributing to 65% total energy intake)
What this could lead to
If successful, this study could help identify which diet composition is better for heart and metabolic health, and how genes influence that.
What could go wrong
This is a small, early-stage observational study (60 participants) that does not test a treatment. Results may not apply to everyone and won't directly change medical practice.
