Depletion of Liver Fat in Type 2 Diabetes

A Parallel Group Randomized Trial Investigating the Effect of Hepatic Fat Depletion Via a Very-low Calorie Diet on Hepatokine Secretion and Function in People With Type 2 Diabetes


Sponsor

Rigshospitalet, Denmark

Enrollment

42 participants

Start Date

Feb 1, 2024

Study Type

INTERVENTIONAL

Conditions

Summary

The aim of this randomized trial is to determine whether liver fat depletion via a short-term (i.e., two weeks) very-low calorie diet will restore the normal exercise-induced secretion of a signaling protein (fibroblast growth factor 21) from the liver in people living with type 2 diabetes. Participants will have their liver fat, body composition, and various markers of metabolic health assessed and then will be randomized to either the very-low calorie diet intervention or a free-living control group for two weeks. Upon completion of the two-week intervention period, participants will redo all of the pre-intervention assessments. The changes in the assessments from before vs. after the intervention period will be compared between the two intervention groups (i.e., the very-low calorie diet group vs. the free living control group).
